Re: Carrier bearing mounting bolts, cotter pin bolts?

I dont think a cotter pin would be as effective as a lock washer in that application. I have had several of these trucks and never observed a hole in the bolt for a cotter pin used in that location. so dont read too much or over analyse the hole deal.
