I recently had my car's rear differential fluid changed by a mechanic. After about a week and a half the differential started to produce a whining sound whenever I go through a slow tight turn. I found out from the mechanic that they didn’t add a friction modifier for my LSD. Could not adding this friction modifier produce this problem? Any response would be greatly appreciated.
have the same problem?
