Please can anyone tell me how I know how to see what kind of rear diff i have,I
called the dealer, they won't tell me!?
Need to know which oil te use, maybe with slip dope?
Thanks a lot!!

 

If you are wondering about if you have the factory G80, then you are supposed to use regular diff fluid anyway. Check the glove box sticker, look for all of the 3 letter / digit codes. If you find one with G80, you have it. If you do, use only regular diff fluid, as the G80 is a mechanical locker, and does not require any traction modifiers.

 

Like Tho said check the glove box sticker and post any code you have that starts with a 'G' on here and we can tell you exactly what gearing you have (or at least what came factory).

 

Thanks, I looked it up, it was readable too! I've found the G 80 code too!

Now I know what to buy.
Manny thanks again!
