my brother has a 1998 grand cherokee tsi and the rear differential is making a horrible winding noise. He asked me what he can do about getting a new one. i personally don't know about swaping out differentials on cherokees in comparison to wranglers. will a d35 like i saw on the swap meet page for a tj fit into his 98 cherokee? any knowledge on this topic will prove to be very helpful.
