Which Spindles Will Work with the Trailer Hub Assembly for 2,000 lbs Axles

Expert Reply:

You can use any of three spindles with the Trailer Hub Assembly - 2,000 lbs Axles - 5 on 4-1/2, item # 34822545BX. I have listed these spindles below. The main difference in these spindles is the mounting dimensions on the inboard end of the spindles. the bearing seal and threaded portions of the spindles are all the same.

Spindle 1.25 inch RD x 4 inch STUB Item, # R104BT8
Spindle 1-1/2 inch Square x 4 inch Long Stub, for 2,000 lb. Trailer Axles, Item # SP204BT8
Spindle 1.38 inch RD x 4 inch STUB, Item # R104BT8-38
