If he does change the rear diff fluid , make sure he uses the chrysler synthetic gear oil and their friction modifier. Just a rec. , but from the few I've seen with problems , not having the OEM stuff is what made the difference. Same with the trans, if it developes a 'judder' going into 'lock-up', change back to chrysler ATF+4. -
