Expert Answers about Trailer Jack


  • Troubleshooting Scissor Jack that Won't Lower When Nut is Turned
  • Are the threads of the main screw turning while the nut is being turned? If so and the jack isn't moving it could be that the barrel nut on the opposite end of the scissor jack has become stripped and now does not allow the jack to raise or lower. If the main screw isn't turning then the problem is that the nut of the screw has some how disconnected from the screw. Either way it sounds like it's time for a new set of scissor jacks. The part # UF48-979032 that you referenced should work...

  • Distance from Trailer Frame to Jack Tube on Pro Series 8K Square Swivel Trailer Jack
  • I went out to the warehouse to measure Pro Series trailer jack # PS1400860383. From the outer square tube to the end of the weld-on pipe that would attach to the trailer it is 2-3/4 inches.

  • Troubleshooting Ultra-Fab Powered Trailer Tongue Jack
  • Some powered tongue jacks like the Husky Brute # HT87247 use the mounting flange that bolts to the trailer frame to make the necessary ground connection. Other jacks like the Ultra-Fab # UF38-944014 use a separate ground wire. Either way that clean bare metal-to-bare metal contact is essential for the jack to operate properly. A weak ground may allow the jack to function under some conditions but it is possible that it may not allow full current to reach the motor. Switches certainly...

  • Best Powered A-Frame Jack Recommendation for Trailers
  • I really like the Husky Brute Jacks like the part # HT87247 as they use ball bearings in the main screw of the jack for a smoother (quicker) operation and because they automatically stop when they reach the bottom or the top of the jack's range. Similar jacks will allow you to over-extend them and damage the threads, but not this one. This jack also has a 4,500 lb lifting capacity so it is more than strong enough for nearly every application. You should note that this figure does not...

  • Purpoose of the Shaft that Sticks Out of the Opposite Side of the Crank Handle of Jack PS1400950376
  • The shaft that comes out of the other side of the jack on the part # PS1400950376 that you referenced is designed for attaching to a follow leg so that the jack can be used as a landing gear set. It would turn with the crank handle. The closest jack we offer to this one that does not have that shaft would be a topwind jack like the part # BD182304.

  • How Does the Bulldog 7.2K Square Jack Mount
  • Bulldog Square Jack # BD180455 is a weld-on application. It would need to be welded to a flat, steel surface. Welding should be performed by a professional welder to ensure the jack maintains its capacity (7,200 pounds).

  • Troubleshooting Powered Trailer Jack that Doesn't Always Power Up and Down
  • Make sure the main ground wire on your trailer harness is connected to a clean metal surface of your trailer frame. It sounds like your jack has a weak ground and because of that it doesn't want to operate consistently. By improving the ground of your trailer harness the jack should start to function normally again.

  • Replacement Drop Leg For Stabilizer Jack On 1994 Eagle Trailer
  • We offer one replacement drop leg for a Fulton stabilizer jack. If you have a Fulton jack on your trailer this may work well for you. This is part # FSJ40324. I have attached a photo of this drop leg that has the dimensions noted you can check out. You would need to measure the dimensions of the upper leg on your trailer to see if this would be a match. If you find it does not match I recommend replacing it with one of the jacks on the attached product page like the Atwood Stabilizer...

  • How to Lubricate the Bulldog Round Topwind Trailer Jack # F1413060334
  • Since you are having problems cranking the Fulton F2 Swing-Up Trailer Jack # F1413060334, I assume you have some rust or corrosion on the inner tube or on the main screw. Also, there could be a possibility that the old and the new lubrication had an adverse chemical reaction. This can lead to rust, pitting, scoring and breakdown of the greases ability to lubricate. I recommend greasing the inner tube, you can use the lithium grease like # L11350 for this, and cleaning out all of the...

  • Recommended Leveling Jack System that Bolts onto Chassis of Mercedes Sprinter Motorhome
  • I recommend using the Leveling Scissor Jack Set, # JSC-30. This set is designed to be bolted or welded to a flat surface on the bottom of a motorhome frame rails or chassis. These 2 leveling scissor jacks with 5,000-lb capacity each will keep your motorhome level and stable. Each adjusts from 5" to 30" inches as your situation requires, and the bow-tie base steadies the jack on soft surfaces. These stabilizers will help prevent your motorhome from rocking back and forth or side to side...

  • Will Atwood Stabilizer Jack # AT82301 Fit 2005 Fleetwood Taos Pop Up Camper
  • The Atwood Stabilizer Jack, # AT82301, is a universal fit stabilizer jack designed to fit nearly all pop-up campers so it should work great as a replacement for the current jacks on your 2005 Fleetwood / Coleman Taos. Just to confirm, I recommend comparing the measurements of the Atwood jack to those currently installed on your trailer. Part # AT82301 has a bracket height measurement of 11-1/2 inches retracted and 17-3/4 inches extended and mounting holes center to center are 3 inches.

Email me back if you can find more info on your landing gear set so that I can see if we have a repair kit for it.

  • Recommended 1200 lb Fulton Swivel Jack for Utility Trailer
  • Are you speaking of an angle-iron type frame, or a C-channel? The Fulton # FTJ120W0301 you referred to which is a weld-on application would be an excellent choice. A bolt-on version is available, part # FTJ12000101. Both jacks are identical except for the way they'd mount to the trailer. If you have an angle iron frame and not the C-channel, I wouldn't use the bolt-on version without boxing out the spot on the trailer frame where you're wanting to install the jack. A piece of square...

  • Motors On Bulldog Landing Gear Move Slightly when Extending/Retracting
  • I think what you are seeing is an example of Newton's third law of motion. The force of the motor turning is causing the housing to move slightly, similar to when you see a car rev its engine and the whole car moves (vertically). But you will want to check to make sure the hardware holding the motors to the legs is all tight. Also make sure that the weight of the trailer does not exceed the capacity of the jacks.

  • Will Fulton Marine Jack Fit Trailer Mounting Plate For Shelby Jack
  • The Fulton jacks are not compatible with a mount used for Shelby jacks. Typically, the Shelby jacks use a mounting plate that is bolted on instead of using a snap-ring like the Fulton Jack, part # FTJ120W0301 uses. We do offer a jack that uses a plate similar to the Shelby mounting plate. It is part # FXP10W0301. This jack has a 1,2000 lb weight capacity and has a 10 inch lift. The plate used for this jack is part # P9012-00. I have attached a photo of the mounting plate with the...

  • Electric A-Frame Jack that can be Mounted Sideways to Allow Tailgate to Open
  • Take a look at the Ultra-Fab Electric A-Frame Jack, # UF38-944014 with 2-1/4 inch outer tube diameter, and # UF38-944016 with 2 inch outer tube diameter. Both of these jacks could be mounted so that the motor housing is facing the front of the trailer or either side of the trailer. Mounting it to the side will give you a little over 2 inches of additional clearance. If this still isn't enough to allow the tailgate to open, it is certainly possible to have a steel plate welded further...

This Pro Series jack may fit on the mount for your Fulton snap-ring jack but depending on its exact age it may not be an exact fit. My contact recommended you use the brand-specific mount for your jack. We also offer pipe-mount type swivel jacks...

  • Recommended Replacement Atwood A-Frame Sidewind Trailer Tongue Jack for 2003 Fleetwood Pioneer
  • We do offer a 2000-lb-rated side-wind A-frame tongue jack from Atwood, their # 273400. This jack fits a standard 3-hole A-frame mount. The jack does not include a foot or wheel but we offer both, either foot plate # 82650 or caster wheel assembly # 80552. Please note that the foot plate does not reduce jack capacity but that the caster wheel does cut the jack's rating to 1000-lbs.

  • Will a Different Brand A-Frame Trailer Jack Fit In Place of a Shelby Jack
  • A-Frame jacks all use the same bolt pattern. Most have slotted holes that allow for a little wiggle room. Some even have more than one set of mounting holes just in case there is a non-standard pattern on the trailer. If you can tell me the capacity you need and if you need a wheel or foot I can make some recommendations. I have included a link to all of the A-frame jacks we carry.

  • Powered Jack and Sliding Tray for Generator Recommendation
  • For your 10,000 lb trailer I would go with the Husky Brute Powered Jack part # HT87247. This jack has a 4,500 lb lift rating that would be more than powerful enough for your setup. I attached an install video for you to check out as well. For a sliding tray it sounds like you are looking for the part # KV-36. You would need to supply the plywood floor for the tray, but the depth of this tray is 36 inches and should work well for you for your generator.

  • Electric Landing Gear Motor Stalls and Clicks when Under Load
  • I have been hearing about this issue a lot lately and it is either the motor or the gear box if not both. The gear boxes and motors are available as replacements for most landing gear systems but to be sure I would need to know the manufacturer and model landing gear that you have. Gearbox # LG-179015 is a likely fit. It will fit Stromberg-Carlson, Lippert, Venture, and Atwood systems. The motor is a little trickier but knowing the manufacture and model of the landing gear will help.

  • Will Ultra-Fab Electric Landing Gear Set # UF17-943010 Fit 2003 Newmar American Star 5th Wheel
  • The Ultra-Fab Deluxe Electric Landing Gear Set # UF17-943010 is identical to many OEM sets supplied by a variety of 5th wheel manufacturers. I checked with Newmar to see if they could confirm the original jacks on their 2003 5th wheels but they could not. However the technician I spoke to said he would be quite surprised if they were not a perfect drop-in replacement. The jack sets includes new brackets in the event they do not fit yours.

  • It is possible to add a caster wheel assembly to the Ultra-Fab Electric A-Frame Jack # UF38-944037. We offer Atwood part # AT80259 that will fit the jack's 1-3/4-inch diameter inner tube. Do note that this wheel assembly is rated for 1000-lbs, while the jack itself is rated for 3500-lbs. This means that if you replace the standard jack foot with this wheel the jack's overall capacity will be reduced to that of the lower-rated wheel, 1000-lbs.

  • A-Frame Jack Recommendation Where Jack Handle Space is Limited
  • While we don't have a jack that has a removable handle I believe I have a solution for you. It sounds like you have limited clearance for using the handle of your trailer jack. A jack like the Pro Series Jack part # PS1401000303 has a handle that allows you to swivel it and get it around obstructions like a propane tank. I attached a review video for you to check out as well.

  • How Does an Electric A-Frame Trailer Jack Get Power
  • A-Frame powered trailer jacks such as # LC285318 get power from a trailer mounted battery and not from AC shore power unless there is a converter than converts the AC power to DC power and it is then connected to the jack. This would be uncommon.

  • What Size Battery Should be Used to Power an Ultra-Fab Electric A-Frame Trailer Jack
  • The 3500 pound Ultra-Fab A-frame jacks such as # UF38-944037 have a 25 amp circuit breaker to handle the draw of the motor so the battery will need to be rated at least that high which usually isn't a problem for 12 volt car batteries. The slow blow fuse is actually a 30 amp. A breakaway battery will not be sufficient since the amp hour rating is too low. You really need an actual car battery.

  • Can 7-Way Operate Powered Trailer Tongue Jack if Trailer Battery is Dead
  • A powered trailer tongue jack like the Stromberg Carlson Camper Jack # JET-3500 is best wired to a dedicated battery on the trailer. If the battery is dead then the trailer's 7-way connector won't be able to deliver enough current to operate the jack. A 7-way 12V circuit is intended to deliver a small maintenance charge to a trailer battery that is in good shape or to pass enough juice for a camper dome light for example, but not to power a trailer jack. The vehicle's 12V feed on the 7-way...

  • Replacement Jack Recommendation for Replacing Shelby 5764A Jack
  • Your Shelby jack that you are looking to replace has a 1,200 lb capacity. The MaxxTow Jack part # MT70149 would be a great replacement jack that has even more capacity at 1,500 lbs. I attached a review video for this jack for you to check out as well.

  • Can a Powered A-Frame Jack Use Trailer Wiring 7-Way as Power Source
  • As long as the 7-way on your 2011 Toyota Tundra has the 12 volt circuit active and you wire the # BD500185 to the 12 volt circuit on your trailer 7-way (the 9:00 pin), the jack would work. It's typically preferred to power the jack off of a battery, but this method will work as well.

  • Will Trailer Valet Handle be Able to Turn on Boat Trailer
  • You would have to mount the Trailer Valet # STC-V211 as far forward on the trailer tongue to be able to turn the jack handle without hitting the boat. Since the trailer valet sticks out further than a traditional jack you should not have a problem.

  • Recommended Replacement Motor For Landing Gear With Atwood 75721
  • It sounds like the clutch in the motor may be failing on your Atwood landing gear. It may be slipping which is causing the clicking sound. Since you said helping the motor with the manual crank helps the gear box will not be the problem. The replacement motor you need is part # AT75367. This will attach directly to the gear box you have and would be a great fit. I called my contact at Atwood and they told me the legs of the landing gear are what the weight capacity is based off of...

  • Can Stabilizer Jacks be Used to Lift RV a Little
  • To answer the last question first, a stabilizer jack such as # JSC-30 would be used until there was just enough tension to keep the trailer or RV from rocking. For actual lifting you would need a different device. So assuming that the RV was level these stabilizers would help prevent it from rocking back and forth or side to side (depending on where they were mounted) while you move around inside. If you were to try to lift weight with them you would have a very hard time because it...

  • Solution for Powering Landing Gear Jack on a Trailer with Dead Batteries
  • Your husband's idea is the one to go with. Using a jumper cable run power and ground from a good vehicle battery to the wiring of the jack so that you can power them. Without knowing what landing gear you have on your trailer it's pretty hard to know if there is a manual override. Most likely there is, but it's hard to say for sure one way or the other.

  • Husky Brute A-Frame Powered Jack Recommendation for a Pioneer Fleetwood Travel Trailer
  • For a powered electric A-frame jack the Husky Brute part # HT87247 would be an excellent option. This jack has a ton of positive reviews from our customers who have tried it. The warranty is 1-year, not 30 days. The screw of this jack uses bearings that reduce noise and wear and operates more efficiently than standard screw systems. Automatic stop prevents damage to gears as well. Most jacks will let you over extend them and damage the threads. This one does not do that.

  • Landing Gear Jack Recommendations for a Livestock Trailer
  • If you are considering a dual jack setup like the part # BD500162 that's what I would recommend. Two jacks will offer more stability and since two jacks will be doing the lifting instead of one the cranking will be a bit easier as well. The easiest to use setup will be a powered landing gear set though as it would only require you to press a button. For that the Bulldog part # BD500161 would be a great option.

  • Why Would a Powered Trailer Jack Only Work When Connected to Tow Vehicle
  • The Electric A-Frame Tongue Jack # JET-3500 grounds through the mounting bracket of the jack. If your trailer isn't hooked up to your tow vehicle when you are trying to use the jack the problem would be that it isn't grounding properly. If you run the ground of your trailer battery to the trailer frame it should work.

  • Dimensions on Atwood Premier Performance Series Power Jack

They were able to tell me that the distance from the mounting plate to the top of the motor box is just over 29-13/16 inches. I was able to go out to our warehouse to measure the distance from the center tube to the rearmost point of the motor box. This distance measured just over 2 inches.

  • Can Shorter Bolts Be Used to Install Trailer Valet
  • You could definitely replace the mounting bolts of the Trailer Valet Swivel Jack and Trailer Mover # STC-V211 with shorter bolts that would fit your trailer. Your best option would be to measure to see how much shorter you would need the bolts to be and then take them with you to the hardware store and pick out a set of nuts/bolts that are the same diameter and the desired length. I would go with at least Grade 5 hardware.

  • Way to Power the Stabilizer Jack JSC-30-IND

  • Recommended Marine Power Jack And Charger For Boat Trailer
  • A marine power jack like part # AT80524 requires a battery that has at lease 10 volts of direct current output to operate. You will want to make sure the battery you plan on using for the jack has at least that much power. The # AT80524 draws from 8 to 45 amps so you want to make sure you have enough battery power. I recommend a battery box like part # DW03189. This is a vented box that measures 17 x 9-3/4 x 10-3/4 inches and includes all of the installation hardware. A 7-way trailer...

This attaches to the trailer frame and is used as a jack with a 15 inch lift and a dolly. This has a 2-speed gear box which can make cranking the handle even easier.

  • Landing Gear Recommendations for 12000 lbs Trailer

These jacks will bolt on to the trailer frame and function independently from one another. This helps to level the trailer when on uneven terrain. I have included a link to the installation instructions for your review.

  • The Robofoot of the Atwood Powered Jack part # AT81069 that you referenced can be removed, but it can not be replaced with a standard foot. If you needed something to like a foot to spread the weight of the trailer out you could use the levelers like part # UF48-979052 with the foot off of the jack.

  • Landing Gear Jacks for a Keystone Cougar 5th Wheel Trailer
  • Bulldog square weld-on jack # BD182513 could potentially be used on a 5th wheel trailer but it really is meant for trailers with exposed frames and doesn't have stops on the outer tube for brackets like landing gear jacks have. If you have brackets already then you would just need to weld on some stops to the outer tube and the heights needed. For a tandem, manual landing gear set you could use # BD500162 which is both legs with the stops already on them, brackets, and connecting rod....

  • Why Does Electric Landing Gear on a 5th Wheel Trailer Go Up But Not Down.
  • If the motor is not running when you are trying to retract the landing gear then there is likely a problem with the switch and it will have to be replaced. We might have the switch but I would need to know the model landing gear you have on your trailer. If the motor is running and it will not go down then there is likely a problem with the gear box, gears in the legs, or a problem with the screw and/or nut inside the jack legs that is not letting it go down. Motors and gear boxes can...

Take a look at the Bulldog Rack-and-Gear Jack with Steel Wheel, # BD162300.

  • Replacement A-Frame Jack for 6750 lb Travel Trailer
  • From your description, it sounds like you're needing an A-frame jack. Given the weights you've provided, your trailer likely has a maximum tongue weight of around 1000 lbs. I typically recommend folks go with the heaviest capacity jack they can, this makes for easy operation and long life for the trailer jack because it's only using a percentage of its capacity. The Bulldog # BD1700100317 with its 5000 lb capacity would be a great choice. The bracket to the top of the jack is similar...

  • Swivel Jack with Wheel with Enough Lift to Lift Trailer Up 25 Inches from the Ground

Depending on how tall the trailer frame is this may or may not be enough. Jack # F141133 has an extended measurement of 27 inches so provided the trailer you have does not have a bottom-mount (underslung) coupler it will provide...

If you look at the diagram I have included you will see that they have measured from the top of one to the top of the other and that is 16-1/2 inches. Since the weld stops are 1 inch tall the measurement is 17-1/2 inches just like what you need!

  • In the install video I attached the power wire (blue wire), must not have been needed for the rest of the trailers wiring as the other end that would run to the trailer was not connected to anything. Our installer ran the power circuit straight to the jack. If your jack isn't working the problem is either the power wire or the ground of the jack. Since it grounds through the mounting hardware the problem is most likely the power wire. You will want to verify that the circuit you ran...

  • Replacement A-Frame Jack Recommendation for a 1992 Pace Enclosed Trailer

The Pro Series A-frame jack part # PSRV20000103 should work well for you as it has a 2,000 lb capacity and 14 inches of lift. For a foot you would want the part # PS1400700340, or for a wheel part # PS1400750340. You should note that using a wheel like this will cut the overall capacity down to 1,200 lbs.

The great part about this jack is that if it doesn't fit the mount you have, it comes with a mount of its own that you could have a professional welded install. This jack is rated for 1,200 pounds. I have linked a video review of this jack for you.

The higher the capacity of the jack the easier it will be for it to operate and the longer the jack will last. That is why I recommend going with a 4,500 pound capacity jack such as the Husky Brute # HT87247. I have included a link to all of the powered A-frame trailer jacks we carry.
