Expert Answers about Dexter Axle

  • How To Determine the Weight Capacity For 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:...

  • How to Adjust Electric Drum Trailer Brakes
  • You are correct. On drum brakes that do not self-adjust, you would manually adjust the brakes using the star wheel on the assembly. Once you cannot turn the wheel, you turn the star wheel the other direction until the wheel can spin and you hear a slight constant drag on the brakes. If the brakes are not constantly dragging it could indicate wear on the shoes or drum. I have included a link to a video and at about the 4:39 mark our installed begins adjusting the brakes.

  • Recommended Trailer Wheel Bearing Grease for Dexter Axles
  • Usually when you replace parts that get lubricated, you clean all of the existing grease first before adding any new grease, just in case there is a compatibility issue. Since you are using Dexter axles and replacing components with Dexter parts, the grease will be compatible. For wheel bearing grease, use LubriMatic Disc/Drum Brake and Wheel Bearing Grease, # L11465, or # L11380. This is a polyurea-based grease that is compatible with most grease formulas of the same or similar chemical...

  • How to Determine the Size of a Trailer Hub Assembly for Replacement
  • To determine the size of the hub assembly you need to purchase you have to determine which bearings are in the old assembly. If the old assembly has L44649 inner bearings, you would use the hub you chose # 8-258-5UC1. If the inner bearings are marked L44643, you will need # 8-258BTUC1. If you do not have the old bearings, you need to measure the inner bearing surface on the spindle to determine if the 1.063 inch dimension or 1.00 inch dimension will be needed to accept the bearing. You...

  • How To Determine the Correct Replacement Trailer Hub Assembly
  • The best way to determine which hub assembly you will need is by the bearing numbers. The item you selected, Trailer Hub Assembly, part # 8-258-5UC1, is a replacement hub which uses Inner and Outer Bearing # L44649. The bearing numbers will be stamped or lasered onto the flat back side of the bearings. The other things you will need to determine are the bolt pattern, the size of your trailer wheel, and the axle capacity. Part # 8-258-5UC, is compatible with a 5 on 4-1/2 bolt pattern....

  • How To Measure the Bolt Pattern on a 15 Inch Wheel With 5 Lug Bolt Holes
  • When measuring to determine the bolt pattern of a wheel with an odd number of lugs, like a 5 lug wheel, you are basically measuring the diameter of a circle that would run through the center of each lug hole. If you are measuring the wheel the easiest way is to measure the distance between the center of one lug hole to the center of the lug hole adjacent to it, then look on the chart and if that measurement is 2-5/8 inches the bolt pattern is 5 on 4-1/2. If it measures 3 inches the bolt...

  • Replacing Mobile Home Trailer Hub With a Hub that is Compatible with Standard Rims and Tires
  • To determine if there are compatible hubs and associated bearings to replace your current hubs to a more standard size you will have to take several precise measurements on the spindle of your axle. It is recommended to use a set of dial calipers to obtain these measurements. You will need to measure the seal, inner bearing, and outer bearing. It is also possible that there may be bearing numbers stamped on these parts as well, and those would be helpful in obtaining the correct replacement...

  • Testing a Vehicle Side 7-Way Trailer Connector for Proper Function
  • To check the pins on the vehicle side 7-Way, you can use a circuit tester or the volt meter. The circuit tester will show you if a signal is coming through on the pin you are testing while the volt meter will tell you that and how much voltage is being sent. When you test the brake circuit pin on the 7-Way, it may be more beneficial to see how much voltage it is sending through. If you are facing the 7-Way, using either tester, you will test for the proper signal as follows: 1 oclock...

  • Troubleshooting Why Trailer Brakes Lock Up While Driving
  • If you have electric brakes, there could be several reasons why they are locking up while you are driving. There could be a malfunction inside the brake controller, a problem with a ground, a short in the wiring, or a problem with the magnets. To test the brake controller, sever the blue wire a few inches from the back of the controller. Use a circuit tester like # 3808 if needed to test the blue wire on the brake controller side. Fully apply the manual override and the blue wire should...

  • Troubleshooting Trailer Brakes Locking Up and Brake Controller Reading No Trailer Connection
  • This could be a ground problem, a problem with the trailer connectors, or a problem with the brakes. The first thing I would check is the trailer connectors on the truck and trailer. Make sure they are clean and free of corrosion. Corrosion could cause a short between the 12 volt power wire and the brake output wire. You should also check for dirt and corrosion on the back side of the connectors. If this does not solve the problem, you can also make sure that the trailer is pinned out...

  • Can I Guess or Estimate Axle Weight Capacity By Number of Lug Nuts
  • I do have a few easier options for you to determine the weight capacity of an axle other than using the bolt pattern or the number of lug nuts. The problem with using the bolt pattern to tell the axle capacity is that an axle may have the a bolt pattern that could be more than one weight capacity. The easiest would be to look on the trailer VIN plate or sticker that lists the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could...

  • Why The Axles Cannot Be Rotated and Original Spring Seats Be Reused When Flipping Trailer Axles
  • The reason you will not want to rotate the axle and just reuse the spring seat is because there is a bow to the axles that flattens out as the weight of the trailer is applied to the axle that if you rotated the axle, the bow would flip and the alignment of the trailer tires would be way off and you would encounter problems with how the tires wear and with overall trailer handling. This is why the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00 that you referenced includes...

  • Trailer Brakes Lock Up When Connected to Truck
  • There are a few things that can cause the brakes to lock up on a trailer. First, disconnect the trailer from the vehicle. Then use a circuit tester like # 3808 if needed to test the connector on the vehicle. Have someone sit in the truck and run through the various functions to make sure everything is working. If any of them are showing a constant 12 volts, and the matching pin on the trailer side goes to the brakes, that would be why the brakes lock up. This is especially an issue on...

  • Does a Trailer with Two 3,500 Pound Axles have a Gross Capacity of 7,000 Pounds
  • Most likely, the trailer would be rated for 7,000 pounds gross if it has two 3,500 pound axles. But there should be a sticker or plate somewhere on the frame near the front of the trailer that lists its official capacity. Also, the trailer can only be rated as high as the lowest rated component. So for example if the coupler is only rated for 6,000 pounds and everything else is rated at 7,000 then you have to go by the 6,000 pound amount.

  • Recommendation For Spring Over Axle Conversion Kit To Use on Trailer With 3,500-Lb Axles
  • The typical axle diameter for an axle that is rated for 3,500-lbs is 2-3/8 inches. Some can have a 3-1/2 inch diameter, but it is very rare. I would recommend to use the Dexter Trailer Springs Over-Under Conversion Kit, part # K71-384-00, you have referenced, which is designed for the 3,500-lb axle with the 2-3/8 inch diameter. The Dexter Trailer Springs Over-Under Conversion Kit, part # K71-385-00, is designed for the 3-inch diameter axle that is used on 6,000-lb and 7,200-lb axles. I...

  • How to Determine the Bolt Hole Pattern on a Trailer Wheel
  • The Trailer Hub Assembly, # 8-259-5UC1, has a 5 on 4-1/2 bolt pattern. To determine the bolt pattern of your trailer wheels, there is a simple way to measure. If there is an EVEN number of lugs, you will measure center to center on lugs directly across from each other. For example, if the wheel has 6 lugs and the center to center distance between 2 that are across from each other is 5-1/2 inches, then the bolt patter is 6 on 5-1/2. If there is an ODD number of lugs, you will measure...

  • Troubleshooting Factory Electric Brake Controller Not Working on a 2005 Ford F-350
  • I agree that you most likely have an issue on the truck side. The voltage at the brake magnets when the vehicle is sitting still and the brake pedal is pressed will only read a small amount with the Ford integrated brake controller on your truck. If you are using the manual slide to activate the trailer brakes you should get somewhere between 12 and 13 volts with the controller set to the maximum setting. If this is the case there may be an issue with the brake controller. The 2005 and...

  • Tips for How to Identify a Trailer Axle
  • Depending on how the trailer was made, there will be a few spots you can check to identify the axle. First, if the trailer was pre-made by a specific company, you may be able to find this information in either the paperwork or on a placard somewhere on the frame. Sometimes, the axle identity is stamped into the axle itself or into the hub if it was purchased as a complete assembly. If you cannot find any markings or notation for the axle, you will need to look for replacement parts...

  • How to Determine if Trailer Has Self-Adjusting Brake Assemblies
  • If your current brake assemblies are self-adjusting, once the hub/drum is removed you will be able to see the adjuster cable extending across the brake assembly as shown in the photo I have edited for you. If you find you do not have them, you can certainly replace your existing brake assemblies. You will need to initially adjust the brake assemblies, but after that they will be self adjusting. I have linked you to a video showing how to adjust brake assemblies, click the link and fast...

  • One Side Of Electric Trailer Brakes Are Locking Up When Braking
  • There are a few things you can check to make sure the brakes are adjusted correctly, but it sounds like there may be a short in the system. I would start by checking the trailer wiring connector on the truck and trailer for corrosion. If there is corrosion in either connector, it will need to be replaced. Next, I would inspect the wiring on the trailer, for any cut or frayed wires. It is possible that maybe only one brake assembly is getting power. You will also want to check the ground...

  • Options for Adjusting Trailer Height on a Gooseneck Livestock Trailer
  • Mounting your axle under your leaf springs will lift your trailer more than 7 inches (4 inches for your axle diameter plus 3 inches for the thickness of your leaf springs and spring seat). Since you have a livestock trailer, that would not be the best option to level out your trailer. The first step that I would take is to check the coupler on your gooseneck trailer. Most gooseneck trailers have adjustable couplers that allow you to adjust the height of the trailer at the gooseneck hitch....

  • How to Determine the Correct Hub Assembly for a EZ Loader Boat Trailer Tapered Spindle
  • The only way to be sure the Trailer Hub Assembly, item # 84545UC1-EZ, will fit on your spindle would be to take some measurements or get the bearing and seal part numbers to match up. Since it sounds like you cannot get to the bearings to record part numbers, you will need to use a dial caliper or similar precise measuring tool to take the measurements. The bearings in the # 84545UC1-EZ hub assembly have inner dimensions of 1.378 inches for the inner # L68149 bearing and 1.063 inches...

  • Proper Way to Tighten Trailer Spindle of Castle Nut
  • After you've packed the bearings and assembled everything, carefully slide the hub assembly onto the spindle and install the outer bearing. Install the spindle and tang washer and run the spindle nut down finger tight, then rotate the hub back and forth then rock the hub side to side to make sure everything is seated properly. This will have had provided more room on the spindle, so run down the spindle nut with your fingers a bit more. The hub should spin freely, with a bit of brake lining...

  • Should I Put Brakes on the Front or Back Axle of my Tandem Axle Trailer
  • Typically trailers will carry more of their weight on the front of the trailer, so you would want to put the brakes on the front axle as it will most likely carry more weight while braking. Also, when braking, weight will shift forward from the inertia of the stop, so that would put more weight on the front axle. Click the picture to the right to see a picture that displays how tandem axle trailers typically distribute their cargo weight on their two axles. If you have a trailer that...

  • Troubleshooting Electric Trailer Brake Assembly That is Running Hot
  • I would recommend completely ruling out the bearings by closely examining them and the spindle for discoloration caused by overheating. If you have determined that it is the brakes that are hot, and not the hub itself, I would recommend readjusting the brake assembly. What you are experiencing could certainly happen if the brake assembly was out of adjustment. To adjust the brake assembly, jack up trailer and secure on adequate capacity jack stands. Check that the wheel and drum rotate...

  • Replacement Axle for Jayco RV Trailer
  • Thank you for providing the reference numbers from your Jayco trailer's Dexter axle. I was not able to cross reference either of these numbers, 123617439 and 1657213, but we can still help you. It appears that one of the other bits of info you found on the axle, HF=85.75 inch, is a measurement of the distance between the two hub faces when hubs are installed. The first thing you need to confirm is the axle's weight rating, which should be stamped onto the axle beam if it does not appear...

  • How to Initially Adjust the Dexter Nev-R-Adjust Electric Trailer Brakes
  • The Dexter Nev-R-Adjust electric trailer brakes can be manually adjusted. There are a couple teeth of the adjustment wheel that are exposed just under the lever that you referenced. I have attached a photo showing the teeth. You will likely need a tool with a fine edge such as a flat head screw driver for the adjustment wheel on these brakes. A brake adjustment tool may be too thick. Without an initial manual adjustment, it could take a few braking attempts to adjust the brakes. I was...
