Shock 10 Bolt Does Call For Synthetic Axle Lubricant I read my owner's manual today and it does say to use synthetic axle lube. GM part no. 12378261 or equivalent meeting GM Specification 9986115. I bought some Mobli 1 synthetic 75w-90 today and plan to change fluid tomorrow. And I did get some GM additive.

Many, including me, prefer conventional petroleum based gear oil. I really believe the 7.5 rears hold up a little better and surely run quieter w/it, although it may cost a horsepower, or 2. Just my opinion, though....WJ
