Question:

I had asked a question the other day, I dont think I gave enough detail. While traveling with my boat on I noticed an issue with my trailer wheel and immediately pulled over. Bearing Buddy and castle nut were gone and I am lucky I did not lose the tire. The axle spindle looks to be okay, will need to rethread it as it has some damage attached. I am not sure if that is advisable or not, but considering this is most likely a custom sized axle I would prefer to repair. 15902-COTTER PIN SPINDLE 15903-WASHER 1.06 SPINDLE 15910-NUT SPINDLE Can you help with cross referencing the parts listed?

Expert Reply:

The correct replacement castle nut, cotter pin, and washer for a trailer with 1" round spindle is as follows: Castle Nut part # 165686, Cotter Pin part # 165649, and Washer part # SW1000.

Unfortunately, we can't cross-reference trailer mfg. part numbers but the above parts are fairly standardized so there will be no issues with compatibility.
