jmontero146 Posted August 13, 2019 Report Share Posted August 13, 2019 Cant figure out the problem.. my rear differential seems to shudder when making slow turns..had the rear differential checked and put new fluid in it and it still does the same problem..anybody ever had this issue? Maybe transfer case? Quote Link to comment Share on other sites More sharing options...
someotherguy Posted August 13, 2019 Report Share Posted August 13, 2019 (edited) What exact fluid went in? Was it marked for posi-trac units? Was posi additive used? If so...that's the wrong stuff, and can cause incorrect lockup of the factory locker. Eaton Gov-Loc (RPO code G80) uses just plain gear oil, no posi additive. EDIT - lol my bad, I thought your post sounded familiar. You had just posted about similar issues previously.

Richard I drained it just incase and put the correct fluid in it just to make sure.. still does the same thing.. Quote Link to comment Share on other sites More sharing options...
