Expert Answers about etrailer

  • How to Determine Replacement Trailer Wheel Bearing Sizes
  • Trailer wheel bearings are specific to the spindle that is installed on the axle that is on your trailer. You will need to safely support the trailer, remove the wheel and tire, remove the grease cap, remove the cotter pin and washer that secures the spindle nut, remove the spindle nut, and then you will be able to remove the hub from your trailer. Once the hub is removed you will be able to get the part numbers from the inner and outer bearings to determine the correct replacement...

  • Parts for Lugged Hubs on a Mobile Home Axle with 15123 inner and 25880 Outer Bearings
  • It sounds like you have a spindle that uses the Inner Trailer Hub Bearing, item # 25580, that has a 1.750 inch inner diameter. The outer # 15123 bearing has a 1.250 inch inner diameter. I would check the seal surface on the spindle to be sure that it matches the # RG06-070 seal inner diameter of 2.250 inches. Many times mobile home axles use non- standard parts so careful measurement of all of the parts is required. If all of these dimensions match, then you will need to determine whether...

  • How to Determine Axle Position when Building a Trailer
  • There is an easy way to determine axle placement on a trailer. Take a look at the picture I have included. Just plug in the numbers and complete the formula to determine the axle placement. The other factor that is going to come into play is the springs that you are going to use. Once you have the measurements all figured out you can determine which springs are going to work with that set up. I have also included a link to our double-eye suspension FAQ article to the right.

  • How to Gain Ground Clearance for a Travel Trailer that Hits the Driveway When Entering or Leaving
  • There are a couple different ways to raise the ride height of your trailer, but before we choose the best option for you, we will want to take a look at a few things. First, it sounds like you are not towing with your trailer level so you do not hit your ball mount on the driveway. A trailer that is not level can create many problems such as ground clearance and trailer sway. If you have any sway control issues with your trailer, then I would recommend moving your leaf springs above...

  • Can Electric Brakes be Used on a Boat Trailer
  • Traditionally, trailer manufacturers did not use electric brakes on boat trailers because the brake magnet wiring and trailer wiring did not always have the best insulation or water protection. These days, more and more manufacturers are using electric brakes on boat trailers due to improvements in wiring insulation and heat shrink connectors. If you are going to use electric brakes, I strongly recommend using heat shrink butt connectors, like part # DW05745-10, when splicing the wires...

  • Do Nev-R-Adjust Brakes Need any Manual Adjustment
  • The # AKEBRK-35L-SA Self Adjusting brake assemblies will adjust themselves as you drive after the initial installation. The front brakes will always bear a bit more of the braking work, because more of the trailer weight is normally on the most forward axle, but it should not be noticeable. We recommend that you do adjust the shoes when you first install the assemblies, so that your brakes are working as well as they can upon the first use. This would be especially helpful in allowing your...

  • Spare Parts for Harbor Freight HaulMaster Utility Trailer 90154
  • We often hear of weak customer support and limited spare parts availability with "bargain" trailer manufacturers. I found an online copy of the owner's manual for the Harbor Freight Haulmaster utility trailer model 90154 but it includes no information at all about the bearing or seal part numbers it uses. Often these foreign-made trailers use odd bearings that are not commonly available. If you can, pull a hub and find the part numbers on your bearings and seal. Please refer to the linked...

  • How to Test Electric Trailer Brake Magnets to Determine if They Need to be Replaced
  • I would check the magnets for wear before going on to test them with a meter. If the magnets show abnormal wear or if you can see the windings beginning to show through the friction surface of the magnet then they will need to be replaced. To further test your magnets, first make sure the trailer is not connected when performing this test. If the trailer is connected, you run the risk of shorting out the brake controller or various other electrical components. To test the brake magnets...

  • Testing Electric Trailer Brake Magnets with a Multimeter
  • The brake magnets can be tested in the manner you have suggested, just make sure that the trailer is not connected to the vehicle when performing this test. You would not want to short out the brake controller or worse. I would check the magnets for wear before going on to test them with a meter. If the magnets show abnormal wear or if you can see the windings beginning to show through the friction surface of the magnet then they will need to be replaced. To test the Brake magnets with...

  • Where to Install Shackle Straps and How to Determine Axle Position When Building an ATV Trailer
  • For a 3,500 Dexter Straight axle the springs should be placed between 16 and 18 inches on center from the hub face (flat area the wheel mounts against). Placement of the spring centers in any other position will reduce the axle capacity. If you are using a different brand of axle you will need to contact the axle manufacturer for the full capacity spring center dimensions. If you are using double eye springs then the shackle straps will be located at the rear of the springs. The top...

  • Trailer Hub Assembly for a Haul-Master Trailer with 8 Inch 4 Lug Wheels
  • To determine if the Trailer Hub Assembly for 2,000 lbs Axles, # AKIHUB-440-2-1K, will fit on your trailer, we will need to know what spindle is on the trailer. The best way to make this determination is to remove one of the existing hubs on the trailer and acquire the part numbers off of the bearings and seal. You will also need to determine the bolt pattern of the original hub which should be 4 inches from the center of one bolt to the center of one directly across from it. If your...

  • Power To Trailer Brake Magnets But Brakes Are Not Engaging
  • For the 2 wires coming off the brake magnet, either wire can be used for either ground or power. You will just want to make sure that the ground wire has a good connection to a clean, corrosion and paint-free location on the trailer frame. A bad ground connection could be causing your problems. You will want to check to make sure each brake assembly has a good ground connection. If the brake assemblies are not new, you will want to inspect the magnets. If the magnets have windings or...

  • How to Raise and Lower the Domar Stabilizer Trailer Jack
  • Using the Domar Stabilizer Jack, # TJ01RT, is very simple. When the jack is mounted on the bottom of the trailer frame in the up position, all you will need to do is pull the leg away from the mounting bracket (there is a spring that holds the leg in place) and then swing down until it locks into position. Once down, to release the drop leg you will only need to push down on the lever at the bottom of the leg and gravity will pull it down. If you want to use the jack to slightly raise...

  • How to Install an Electric Brake Controller Unit on a 1998 Chevrolet Pickup
  • For your 1998 Chevrolet Pickup, there is no brake controller connector on the vehicle so the wiring for the brake controller will have to be hard wired on the vehicle. You will need just a few items to install a brake controller on your pickup. The items you need are a Working 4-Way connector, item # 118315, if you do not already have one. A brake controller wiring installation kit, item # ETBC7, and a brake controller of your choice. I would recommend the Prodigy P2, item # 90885 for...

  • How to Choose the Correct Brake Assembly for Trailer Axles
  • You will need to do some measuring to determine if the 10 Inch Electric Brake Assembly LH, item # AKEBRK-35L, is the correct assembly for your trailer. Measure the diameter of the mounted brake shoe, the width of the lining and the distance between the mounting holes on center. It may also help if you can determine the manufacturer of your brake. Once you have these measurements you can choose the correct assembly for your axles. It is recommended to change both of the brake assemblies...

  • How To Tell The Difference From Right and Left Electric Brake Assemblies
  • The right and left orientation is determined if you are standing behind the trailer looking towards the tow vehicle. The left side is the drivers side and the right side is the passengers side. Tthe shorter brake pad will always be in the front of the assembly and the longer brake pad on the rear of the assembly, the reason is that the shorter pad will contact the drum first to slow the trailer down and the larger pad will then contact the drum to finish stopping the trailer, so both...

  • How to Replace Interior Ram Jack Rod and Nut # TJD-12000-RODNUT on 12000 Series Jacks
  • Good news! I was able to get a exploded diagram as well as a set of instructions on how to replace the rod and gears # TJD-12000-RODNUT in the # 12000 Series Ram Jacks made after 2012. I have attached them to this page for your convenience. Basically, you will not need to remove or cut the steel plate inside the top of the jack to do this. You will want to remove the cap, then the roll pin that holds the cross shaft into the leg, this will free up the smaller gear that will be removed...

  • How to Determine the Capacity of a Trailer Axle
  • The trailer will have a plate or sticker on it that will list the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that will list the weight capacity. You can also tell the weight capacity of the axle by measuring the diameter of the axle. Here is a list that will show the axle weight capacity based on the axle diameter: Typical Axle Diameters Based on Axle Capacity 1,000-lb - 2,000-lb Axles:...

  • Advice For Installing Leaf Springs on a Double Axle Trailer
  • The easiest way to accomplish this would be to start on one side of the trailer and get the springs in place before bolting the axle to the springs with the u-bolts. Have the axle up on jacks or blocks so its weight is not bearing on the springs. Once the springs are in place on both sides, the shackles will be in the correct orientation so you can attach the axles. The key is to do one side of the trailer at a time. I have included an FAQ article on double eye and slipper springs below.

  • Amperage of Brake Magnets and Size of Wire Used To Connect 7-Way Trailer Plug To Electric Brakes
  • On each individual electric brake magnet the amperage draw would be 3.0 to 3.2 max amps at 12 to 13 volts on 7-inch brake magnets and 3.2 to 4.0 max amps at 12 to 13 volts on 10 and 12-inch brake magnets. The max amperage draw for the brake magnets on a single axle trailer (2 brakes) would be 6.3 to 6.8 max amps on a 7-inch brake system and 7.5 to 8.2 max amps on 10 and 12-inch brake system. The amps will be higher if using a tandem axle or triple axle trailer. I am including a link...

  • How to Determine Hanger Spacing for Tandem Axle Trailer Suspension with 26 Inch Springs
  • Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are based on our preassembled kits, so we will use that as a foundation for your setup. First, I would either replace all of the front and rear hangers with 2-1/2 inch tall hangers like part # 115918 or replace just the center hangers with 2-1/2...

  • Where To Connect Two White Wires From Brakes on Trailer Axle
  • If you are referring to two white wires from the brake magnet that are coming from the rear of each electric brake assembly, then it would not matter which wire is connected to ground and which wire is used for the brake feed. The magnet that operates the electric brakes does not require the wires to be specific. I am including a link to a video review of a electric brake assembly that will show the two wires from the magnet. If you are blowing fuses you will want to check the complete...

  • Can a Harbor Freight Boat Trailer with 4.80x8 Tires be Switched to 175/80-13 Trailer Tires
  • There are several things to consider when switching to larger tires and wheels on a trailer. First you need to consider the height difference. On a 4.80x8 trailer tire, you are looking at a diameter of about 16 inches. On a 13 inch, like # AM3S040, the diameter is 26 inches. That 8 inch difference means that the top of the tire will be 4 inches higher than your existing tires. You would need to remove the fenders, if equipped, for the tire to fit. You also have to consider width. A 4.80x8...

  • Replacement Hub and Brake Assembly for AL-KO 8490
  • Based on what information I could find about AL-KO 8490 hub and drums, it is rated for 3,500 pound axles, has a 5 on 4-1/2 bolt pattern, and is a 10 by 2-1/4 inch drum. If this is the case, we have several options for you. I have attached a link to all of our 10 by 2-1/4 inch, 5 on 4-1/2 hub and drum assemblies for 3,500 pound axles. I recommend the etrailer.com Hub and Drum Assembly # AKHD-545-35-K. This hub and drum uses # L68149 inner bearing and # L44649 outer bearings. If you can...

  • How to Adjust New Electric Drum Trailer Brakes
  • The first step that you will want to take is to jack the trailer up on properly rated jack stands. Make sure the trailer is suspended securely before replacing the brakes. Once you have your new electric brakes installed and the hub and drum mounted, you will want to move to the back of the brake backing plate. There should be a rubber plug at the bottom of the backing plate. Remove the plug and you should see the teeth of a star gear inside the brake assembly. This is the brake adjuster....

  • Brake Controller and 7-Way Trailer Connector For 1995 Chevy C/K 1500
  • As a first step, you would need to select a brake controller. I would recommend the Tekonsha Prodigy P2, part # 90885. The P2 is extremely reliable and easy to use, which makes it one of our all-time best selling brake controllers. Most of the Chevy trucks of that era had a blue and an orange or red wire ran along the frame rail for installing the controller. At the rear of the vehicle, they usually terminate on the end of the drivers side frame rail or above the spare tire. In the engine...

  • Replacement Dexter Brake Assemblies for 023-027-00 and 023-026-00
  • We have direct replacements for the two brake assembly part numbers you listed. You would want part # AKEBRK-35R and # AKEBRK-35L. Or, for never adjust assemblies the part # AKEBRK-35L-SA and # AKEBRK-35R-SA would work as well. Most likely you have a Dexter 3,500 lb axle and the correct bearings would be the # BK2-100. However, since I do not know for sure what axle you have you would need to pull the hubs of your trailer to get the numbers stamped on the bearings so that we can pick...

  • How to Measure the Angle of Trailer A Frame To Determine if a 50 Degree A Frame Coupler will Fit
  • I would use a protractor, see photo, place the protractor on the edge of the inside of one side of the trailer frame and the other inside edge of the trailer frame should be parallel with the 50 degree line on the protractor. Another way to verify the angle is to measure the angle where the frame meets the cross member for the trailer bed itself. This angle should measure 65 degrees on each side, which will give you a 50 degree angle for the coupler. The standard dimension for trailer...
