Rear end grinding 98 laredo 5.2

When i turn either way i get a bad grinding noise which appears to be coming from the back half of the vehicle. I figured it was the rear bearings or diff. So I changed the back wheel bearings and inspected the diff condition. Diff looks mint.
Grinding continues. Doesn't happen until the vehicle is warm. Any thoughts?
Any thoughts?

Part store guy suggested synthetic gear oil and posi-track antislip additive.
Will try that

Do you have a limited slip in the rear? If you don't then don't bother. The friction additive is for the clutches on the limited slip so if you don't have one it's useless. Gear oil isn't going to stop the grinding.

It would have a metal tag on the diff that will say limited slip and another tag with the axle identification on it. Like 44a. Or you can request your build sheet from Chrysler via email. The oil weight will not cause a grinding noise. It's probably a carrier bearing or pinion bearing maybe. That is if you are sure that it's coming from the rear.


Why do you have two threads on the same topic?
