Detailed Description

GKN Automotive supplies driveline components engineered around exact fit and material match, and this boot kit follows that approach for outer CV joint service. The TPE boot material is important on high-torque drivetrains because it helps manage heat while maintaining the flexibility needed to protect the joint. For vehicles originally equipped with a TPE boot, matching the replacement material is critical to maintaining proper fit and durability. This part cross-references 5QM498203 for the same application.

Installation Notes

Confirm the original boot material before replacement and match TPE to TPE when the factory shaft uses a thermoplastic elastomer boot. Verify joint end and shaft end dimensions, rib count, and position before installation. Clean the joint thoroughly, inspect for wear, and replace any damaged sealing components before reassembly. Use the vehicle-specific fitment listing to confirm whether the application is front outer, front right outer, or front left outer.
