How to Determine The Correct Replacement Trailer Hubs by Bearing Numbers or Spindle Size  

The spindle dimensions are as follows: A is the mounting dimension, B is the seal dimension, C is the inner bearing surface, D is the outer bearing surface and E is the diameter of the threaded portion of the spindle for spindle nut selection. Say…

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…

To replace a spindle, the old one would need to be cut off, and the new one welded into place. This is NOT a job for the do-it-yourselfer. The new spindle must be absolutely square with the axle in order to prevent premature tire wear and wheel…

We can help. So what you would want is the hub part #AKIHUB-440-2-2K that you mentioned as it has the correct bearings that come with it and then since you have a different seal you would need to swap that out with the part #34823 and you'd be…

It will depend on how deep and long the scratch is. You want to make sure the bearing will still get a good purchase on the spindle, but you will also need to make sure the seal will not have a gap that will allow grease or oil to leak out. If the…

If you remove the hub and wipe away the grease on the spindle you can check to see if it is damaged. Look for an scarring, gouges, discoloration, or scoring on the spindle. If the spindle is damaged then the bearings won't ride properly and can…

We do indeed carry a 1 inch inside diameter spindle washer for a BT8 spindle. The part number you need is #SW1000. The washers are sold individually, so be sure to order a quantity of 2.

What concerns me about this situation is the scarring on the spindle. Depending on how deep and how bad the scarring is, a new set of bearings and a new hub/drum assembly might experience the same problem down the road. This would mean that the…

The fact your outer bearing fits on a .75 diameter spindle means we aren't going to have a standard bearing kit to fit since that's not a standard dimension. Can you get me the C dimension as well? It could be that you need the part #LM67048…

I can't get that PDF to open, could you get me the bearing numbers that are listed on the PDF?

I have included a picture that shows the measurements needed for a spindle, bearings, seals, faces, and hubs. The spindle measurements are labeled A through F. A is the spindle shaft diameter B is where the grease seal sits C is where the inner…

We do not offer any hubs that use the bearing set LM11749 and L44649 but we may still be able to help you find replacement hubs that will fit your spindles and have the 5-on-4-1/2 bolt pattern you want. You'll need to measure the spindles at the…
