JPOTM WINNER
I was doing alot of research about that rumbling/grumbling noise I have been hearing since I bought my libby with 27k mi. Always occured at low speed turns and starts. Almost 70k later (and never changing the diff fluid) I finally got sick of hearing it and found this forum and all its information and was ready to test the knowledge and experience of all that shared on this forum
So this past week-end I drained the rear diff, bought some 75-140 synthetic fluid AND the friction modifier. I sparked her up, drove out of the garage and instantly the noise was gone. Magic? I think not, listening to others and just doing what the manual actually says to do....who'd of thunk it
