I havent broken any drivetrain parts yet, but while taking my diffs apart last night to replace the grease with oil, I noticed that the rear planet gears (i guess what everyone is calling spider gears) have wear on them on the backside, right where the small washer is. It looks as if the surface has been chamfered, and one of the gears is worn enough that there is contact with the little square keepers. The front diff looked fine, and I havent gotten to the center diff yet. But this was only after about 6 races on the truck.
Anyway, seems I'll need to rebuild the rear pretty soon.
Anyone having the same issue?
