• Loss of stable differential support in rear-mounted applications

Installation Notes and Tips

Verify rear position and vehicle application before installation. Inspect surrounding driveline components, bushings, and mounting points for wear or damage before replacing the mount. For Jeep Compass, Jeep Patriot, and Dodge Caliber rear differential mount service, confirm the existing mount style and hardware condition during diagnosis. Anchor 3623 should be installed according to the vehicle service procedure and torque specifications.

Quality Assurance

Anchor designs its mounts to OEM standards and uses controlled rubber hardness, bonded construction, and application-specific materials to support consistent fit and performance. The part is built with the same type of engineering focus used across Anchor driveline mounts, including material selection intended to improve durability and vibration isolation.
