Hello my name is ***** ***** thank you for your question.

90
Expert:  Jay replied 10 days ago.

That is only part of it. What is the exact weight oil used.. ?

Customer: replied 10 days ago.
80/90 gear lube
Expert:  Jay replied 10 days ago.

Your truck requires 75w90 Synthetic gear oil. I would start with putting the correct fluid in it and see if that resolves your issue.

Jay, I found out he did use 75w-90 synthetic. Any other possible ideas of why the Pinion or ring gear seems to be in a bind

When you do diff work, you have to make sure everything is shimmed properly and everything has the proper clearances. If something is a little off, it could make noise. So you may want to have the diff work rechecked if the noise is coming from the rear diff
