Question:

I purchased this brake drum/hub assembly for my car transport trailer a few years ago because I hit a curb at 30mph and cracked one of the hubs around the outer bearing. The wheel was not bent and there didnt appear to be any other damage so the brake drum and bearings were the only parts replaced. The trailer is not used very often, 3-4 times a year at the most. I recently used the trailer to haul a car 600 miles and when I got to my destination, the wheel and drum assembly fell off! The bearing was completely gone, the only parts remaining were the inner races which are now seized to the spindle, the outer race for the inner bearing and the grease seal. Im lucky it didnt come off on the highway. This is the first time the trailer has been used on such a long trip since I replaced the drum and bearings on this wheel. Who is the manufacturer of the bearings included with this drum/hub assembly? Are they made in China? My other thought is that I have a bent axle.

The trailer hub and drum assembly # 845476UC3 includes bearings and races from Redline. They are made in China. I would assume you have 5 on 4-3/4 inch bolt pattern but you will need to replace the spindle. Welding on a new spindle is a precision trade craft requiring a special jig installed by an experienced professional. Otherwise, you could continue having the same problem.

Depending on the overall length and if you currently have a round or square, that will determine which spindle you need.

If it's round, you will need # TRU84FR, or # TRU64FR which have a 1-3/4 round stub. If you have a square spindle instead, you need # TRU47FR which has a 1-1/2 inch square stub.

On the other hand, replacing your axles is a solid choice because yours could be damaged. Replacing axles will include the spindle assembly.

You will need Dexter trailer axle # T3584F-8974 if your existing axle beam measures 89-inches from hub face to hub face and 74 inches center to center on the spring hangers.

I have included installation videos for you as well.
