Real Axle Fluid Change??
I'm getting some conflicting info on the rear axle fluid.
What does everyone suggest and is there a traction additive to be used as well?. 1989 300CE. |

We change the rear oil at 90k intervals unless you have a car with a limited slip differential. Then we do the rear oil on 30k intervals. We use regular 80w90 gl5 in the "open" diffs and the lubro-moly 85w90 gl5 for limited slip diffs in those.
If you get a grunt and some chatter after a gear oil change then add some GM limited slip additive and do figure 8's with the car. Joe
