I wanted to post this after running across this problem when I was rebuilding my rear end.

The pinion seal that comes with the master overhaul kits won’t fit the GMT400 trucks at least in the 98 year model, reason being there is a wear ring made onto the yoke thus the seal that comes with the 8.5 master overhaul kit won’t fit.

As far as getting the seal goes you can either buy the whole kit for your local parts house or go to the Chevrolet dealer and buy the seal from them.

Here’s the PN# 26064028 if any one needs it.

IIRC this was a mid-year '97 switch. I remember seeing two styles of pinion seal available when I bought one for my '97 K1500 Suburban with the 8.5" 10 bolt. Thanks for shedding some more light on the situation, I just bought both styles and had my mechanic use the one that worked.
