Question:

I have a pitted spindle where the grease seal rides. Do you carry spindle repair sleeves?

Unfortunately, we do not sell spindle repair sleeves. However, the best way to repair a pitted spindle is to replace the whole spindle or axle. If you are interested in replacing your spindle, you can give me the spindle product number, or I will need to know a few measurements to recommend a new one.

You will want to use a digital caliper like # PTW80157 to get the most accurate dimensions. The spindle measurements are labeled A through F, please view the diagram as a guide.

A is the spindle shaft diameter
B is where the grease seal sits
C is where the inner bearing sits
D is where the outer bearing sits
E is the thread diameter at the end of the spindle for the nut
F is the spindle shaft length

I will also need to know the weight capacity of the axle this spindle is on.

Once I know this information, I would be happy to recommend a replacement spindle for your trailer.

I attached some help articles on trailer spindles and axles which you may find helpful.
