Product Overview

The rear differential mount, OEM number 68091398AA, is fitted to the Jeep Grand Cherokee WK2, covering the 2011-2021 production run across a range of engine variants including the 3.0L V6 turbo diesel, 3.6L V6, and 5.7L V8 HEMI. It's closely related to the differential mount used on the Dodge Durango (68091399AA), so it's worth stocking alongside that part number to cover both Jeep and Dodge differential mount demand.

A worn or failing differential mount typically shows up as clunking or knocking noise from underneath the vehicle during acceleration or braking, vibration felt through the floor, or excessive differential movement. GSK Auto manufactures this mount to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Differential Mount?

Function: The differential mount secures the differential/axle assembly to the vehicle's frame or subframe while absorbing vibration and torque reaction generated during acceleration and braking.

Working Principle: A rubber element inside the mount cushions the connection between the differential housing and the vehicle's frame, isolating vibration and shock from reaching the cabin while still holding the differential firmly in place.

Importance: On a mid-size SUV platform, a properly functioning differential mount is essential for smooth, quiet operation and preventing excess drivetrain movement under load.

Common Failures & Signs: Clunking or knocking noise from underneath the vehicle during acceleration or braking. Vibration felt through the floor or seats. Visible cracking, tearing, or sagging in the mount's rubber body. Excessive differential movement noticeable when accelerating or decelerating.
