The differential mount bushing sits between the differential and its mounting point. It helps locate the differential, absorbs driveline vibration and limits movement as torque is applied and released. Signs this bushing may need replacing include a clunk when accelerating, decelerating or shifting, excessive differential movement, added vibration, and a cracked, torn or separated bushing. Diagnose the cause before replacing, because other driveline and suspension parts can produce similar symptoms.
