TWIMC:
So far I've found 11 grease fittings to lube all on the front end of my truck. Am I missing any at all?? Also I have a rear differential question. My Chevy is a 2002 model 11.5" and I changed the oil in it to CASTROL SYNTEC 75W-90. This oil says it exceeds the GL-5 spec rating. It also has the limited slip additive added to it and I was wondering since my rear end is an Eaton G80 locker will this additive hurt my differential?? Thanx in advance.....................SWH...

Shuffman, per G.M. there is not one TRUCK out there that you put in the additive, only for cars and baby trucks

If you found 11 grease zerks, you found all of them.

The thing is the CASTROL I used had the additive for the limited slip in it already, will this damage my differential??? Yes or No??!!...............SWH...
