    After reading the numerous posts about the driveline clunk fixes, I purchased the GM "miracle" lube specified in the owners manual. Looks to me like the only thing special about it is that it has Teflon infused in it. $44/lb is just crazy money for grease! If I had it to do over, I'd just get Magnalube-G. Appears to have the same ingredients and only $11/lb.

    The GM version DID take care of the clunking for now though ;)

    A little morre truck info might help us figure out which clunk you are refering to. Since it seems that every single model of GM has a different one.:lol:

    the clunk he is referring to is where the rear drive shaft enters t-case common problem mine does the same thing just haven't gotten around to fixing it, we use the GM grease seems to last the longest of all the greases we have used
