I give up
Dealer printed out the following Diff Fluid for Front and Rear. Synthetic Gear Oil GM: 89021677 Canadian: 89021678 Then I call to check on the rear gasket for the diff, $17- Nuts I say.... :bulging: So I ask him to confirm if I need the additive for the rear, he says I don't think so.... :banghead: So, I then ask him to confirm based on the above P/N's he gave me last week, puts me on hold, then says I need the additive.... What gives.... :suspect:
If I cant trust the parts department at the Dealer, who do I trust? :wacky:
So, can anyone provide me with the following.
1. Confirmation on what Diff Fluid for Front and Rear... 70/90 Synthetic
2. Friction Modifier needed? AMSOIL stated it comes in there fluid already.... but get this.... If you hear a little chatter, add a tube of modifier...:emocide:
3. What is the P/N for the gasket. I know I can make one with RTV,, but is there a gasket for back there?
4. After drain and refill, I read that it should be a bit below the fill plug. Then I read somewhere else that after you fill it to wait about 45 min, the level will drop because it will fill the axle slowly, and then you will be able to add the proper amount...
Who can you trust.... The Forum....
