  • How to Pick Out a Replacement Hub for a Trailer
    In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out.

  • Availability of Trailer Hub to Fit Older Short Spindle on Boat Trailer
    If you have an older trailer with the short spindles then unfortunately we don't have any hubs that will fit. I've gone out to our warehouse and measured a handful of hubs in the past but none of them have a shorter length/height. The only option to use current hubs is to either cut off your spindle and replace it with something like part # TRU94FR so that the CE Smith Trailer Hub Assembly # CE13110 can be used, or purchase new axles entirely.

  • How to Determine Hub Face to Hub Face Dimension for Picking out Replacement Trailer Axle
    If you are looking to order a new axle for your 5 foot wide trailer you will need to determine what the hub face to hub face dimension you would need to clear your trailer that is 5 feet (60 inches) wide. You will also need to know the width of your wheels/tires. You will take the figure and divide by half as trailer wheels have a zero offset which means exactly 50 percent of the tire width will be on either side of the hub face. You will want to have a couple inches of clearance between...

  • Assembly Order for Bearings, Races, and Seals for Trailer Hub # 34822BX
    The order of assembly is as follows (from the inside out). First, put the inner race in the back side of the hub, followed by the inner bearing, and then the seal. Insert the hub onto the spindle. Then, insert the outer race, followed by the outer bearing, then the washer, nut, and pin. The grease cap goes on last. It looks like you are putting the race in the wrong place. I have included a link to a video that will show you the process. Also, all the parts you have listed are compatible....

  • Should a Spindle That is Chipping be Replaced
    Anytime that a spindle is starting to take damage you will want to replace it as that will affect the performance of your bearings and seal. In this case since that chipping is right where the seal sits (as you mentioned) that will eat at the rubber seal which will likely cause it to fail. A failed seal will leak grease and cause further damage to your spindle/hub area. From the picture you sent in it looks like you have a round BT8 spindle. For replacements we have parts # TRU94FR,...

  • What is Best Way to Have Trailer Spindles Installed on Axle
    Spindles like # TRU94FR need to be installed by a welder/fabricator with the correct equipment for the job. It's a precision install that requires specials jigs so that the wheel alignment is perfect. Contact local welders to you and ask if they can install axle spindles. If they can't they'll definitely know someone who can.

  • Replacement Spindle for Procraft Trailer
    I was unable to reference a spindle with the number BT151; the best I could find in reference to BT151 is a hub kit for an E-Z Loader trailer, though it did not mention the specific bearings it used which would help identify which spindle you need. Knowing your axle capacity will also help narrow down your choices, or you can measure your spindle with a digital caliper such as # 301-17068 where the bearings and grease seal ride and use that information to compare it to the chart on the...

  • Trailer Spindle that Works with BT100 Hubs
    For your hub that uses L44643 bearings you can use one of 2 spindles: # TRU94FR # TRU59FR I have included links to video reviews of each of these spindles for you. If your bearings do not have L44643 stamped into them let me know what they are and I can see if there is a spindle that will work with them.

  • Are Replacement Spindles Available for a 1995 Stratos Boat Trailer
    We do offer replacement spindles but a bit more information is needed to determine which spindle you will need. One way to determine would be to get a few measurements from your spindle. I will need the diameters for the inner and outer bearing seats and the grease seal seat. I recommend using a precise measuring tool such as a dial caliper because these measurements must be exact, to the closest thousandth of an inch. I am attaching a picture that may be of help when measuring. Another...

  • How to Determine What Replacement Bearings are Needed When Bearing Numbers arent Present
    Another way to determine the bearings and seal you will need is to use a digital caliper and measure the bearing and seal dimensions of the spindle on your trailer. Again, these have to be as accurate as possible. I am including a link to a video that will show you how to take the measurements on the bearings. See the attached picture to see where to measure as well.

As long as there is no discoloring, scratches, or other damage, you may be able to just replace the bearings, race, and seal. If you are planning to replace your hub, I will cover that as well.

  • Constructing an Axle from Pipe and Spindle for Use on Homemade Trailer
    The TruRyde Spindle # TRU94FR that you referenced has a 1-1/4-inch diameter stub. This spindle will fit an axle beam (pipe) with a 1-1/4-inch inner diameter. While you can certainly fabricate your own axle to go on your homemade trailer, assuming you have access to a qualified welder, I suggest you consider buying a complete axle assembly from etrailer. Apart from the savings in time and labor you also benefit from knowing the exact capacity of that system, something you do NOT get with...

  • Which Trailer Hubs Will Fit a BT8 Trailer Spindle
    Trailer spindle requires a hub that uses L44643 bearings and a seal with a 1.249 inch inner diameter. We have a lot of hubs that fit that description. I have linked all of the hubs and hub and drum assemblies that use L44643 inner and outer bearings. The most common axle size for these hubs is a 2,000 pound axle and in the hubs for axles with a 2K capacity the most popular is # AKIHUB-440-2-1K.

  • Replacement Trailer Spindle for L44643 Inner and Outer Bearings
    A spindle that uses both inner and outer bearing L44643 makes it a BT8 spindle, # TRU94FR. Please note that welding on new spindles is a precision job and should performed by a qualified welder with experience welding on spindles. The alternative is to replace the axle. Axles are measured from hub face to hub face and from spring seat center to spring seat center. For example, the picture I have included is for axle # T20BTR-EZ-7258.

    We do have the parts you need for your trailer. I recommend the trailer hub assembly, part # 8-91-05UC1. This is a hub assembly that comes with bearings, races, seals, and the grease cap. The bearings included with the assembly will work fine. The seals in the assembly will not work for your spindles as the inner diameter is too large, but we do have a solution. These are 4 on 4 hubs and include the bolts on the hub and also include the lug nuts. You will need to order part # RG06-010...

  • Which 5 Bolt Hub Assembly is Recommended for Use with the Redline Spindle # TRU94FR
    On the TruRyde Spindle, part # TRU94FR, the hub assembly you would need is an idler hub assembly. An idler hub assembly does not have an integrated brake drum. It will also depend on what size wheel and tire you will be using. If you need an idler hub assembly with a 5 bolt pattern you can use the Dexter hub # 34822545BX. This is a idler hub assembly with a 5 on 4-1/2 inch bolt pattern that will work on 2000lb axles. It will only work with 8 inch to 10 inch wheels. If you need an...
