I have a 2005 LJ with a Dana 44. I did a fluid change on it and drove to work today and there's a grinding noise coming from the rear end while turning. It has 141,000 miles on it. I do the fluid changes every 20,000 miles +/-. I did not put the friction modifier in because it is my understanding the limited slip fluid should not need it. Could this be the cause?
