Where should I get the rearend fluid from when I change it out? Should I use GM stuff or something like Lucas? How much should I need?

I put amsoil in mine when i changed mine. Gm wanted like 21 a qt and it wasn't anything special except grape scent. It takes almost 3 qt and i used the series 2000 stuff. I am an amsoil dealer and i have never had any probems.

 

How much do you charg for 3 quarts. I have the G80 rearend, do I need any additives or anything?

Use some syn 75/90 + 4oz of the LSD additive. The drain and fill plugs accept a 3/8" ratchet.

There is a drain plug on the on the underside of the 10bolt and just make sure to PULL THE FILL PLUG FIRST. It would be bad if you could not fill it back up right?

It takes ~2.8 qts from what I remember.

 

Thanks a bunch!
