I am replacing the bearings on my Coleman PUP. It does not have EZ lube spindles and has the castle nut with cotter pin holding it in place. When I removed the castle nut, there was no washer behind it. Anyways, doing a search for this situation, it sounds like most people have never heard of there being no washer between the outer bearing and the castle nut. The kit I bought from etrailer came with a tang washer but that doesn't apply to my situation. Just wondering if you guys have encountered this. Maybe I will give etrailer a call.
