Question re: gear oil selection for a Cadillac CTS My daily driver is a 2004 CTS (V6). I've got the car on jackstands to replace the rear axle seals since they're both pissing fluid like crazy. The service manual calls for the following fluid:
Neither of those part numbers show up in a GMPartsDirect.com search, but when I search for it online it sounds like people pay $20 per bottle for this stuff.
Since this is my daily driver (in other words, the car I *need* to run) I'm a little hesitant to go to AutoZone and buy my typical Lucas Gear Oil and GM Posi Additive. Am I safe with AutoZone fluids or should I just buy the genuine GM stuff?
Thanks!

i use to work for a cadillac dealership as a tech and i have resealed many of these rearends. if we ever ran out of gm fluid we would use other fluids. as long as its 75-90 or 80-90 you will be fine. and if you have limited slip then use an additive.
