• 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...

• 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.

• 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 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 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 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...

• Is Seal # 442251 The Same as # 171255
• The National Part # 442251 is a single lip seal. The part # RG06-050, 10-19, seals are double lip seals of the same dimensions and will work as replacements for the # 442251 single lip seals. The double lip seals are usually used for applications where the trailer is backed into water and helps keep water out of the trailer hub. For the single lip style seal two of part # 58846 is what you will need.

• 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....

• 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:...

• 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...

• 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...

• 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 Raise a Trailer for More Ground Clearance
• There are a couple of things that you can do to get more ground clearance for your new trailer. First, if the leaf spring stack is attached under the axle then you could use an over/under conversion kit. If the trailer has a 2-3/8 inch diameter round axle use # K71-384-00. If it has a 3 inch diameter round axle use # K71-385-00. This will move the leaf spring stack to the top of the axle and raise the trailer approximately the same amount as the axle diameter. These kits will only...

• Difference Between EZ Lube Compatible Hubs and Regular Hubs
• Some trailers are equipped with EZ Lube spindles, which have a grease fitting or zerk in the end of the spindle, and a small hole in the spindle that lets grease enter the interior of the hub and reach the bearings. This allows grease to be added to the trailer hubs, but the bearings would still need to be inspected and repacked before installation. The only difference between an EZ Lube hub and a non-EZ Lube Hub would be the grease cap. For an EZ Lube hub, the grease cap would have...

• 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...

• The Difference of Single Lip And Double Lip Grease Seals
• The difference between the single lip and double lip seals is that the double lip grease seal will have two rubber lips that are in contact with the spindle. The double lip grease seals are usually used in marine applications to give a better seal and protect the bearings from the water, which can cause damage to them. The best way to determine what grease seals are needed for your spindle is to get the part numbers from the inner and outer bearings from that spindle. If you have the...

• 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...

• 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...

• 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.

• 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...

• 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...
