No shims here and the truck drives great. I do have a question about shims in the rear gearbox. I recently replaced the ring and pinion and pit the stock shims back in , 2 on each side. There seems to be a high spot where the mesh gets a little tighter. Do I shim to the highest spot or let it wear in? I have 1-5 min qual and a 20 min main on it and it still has a high spot. Reshim or leave it alone?
