Couldn't find the oil capacity for the rear end....so like an idiot, I relied on the Dealer's estimate of 3 qts.
When draining, it didn't seem anywhere near that.......pumping in the Royal Purple (less than 1/3 the price of the GM approved oil, dealer price) it started to weep out the fill hole a 1.5 qts.
CRAP....got to thinking, measure the old oil, about the same.....another example of how you can get hosed by the Dealer.....
