What This Boot Kit Helps Address

• Torn CV boot material that exposes the joint to dirt and moisture
• Slipped boot sealing that allows grease loss
• Porous or heat-damaged boot material on high-torque driveline systems
• Noise or vibration caused by contamination entering the CV joint
• Premature CV joint wear after boot failure

Installation Notes and Tips

Verify the original boot material before ordering. If the factory driveshaft uses a TPE boot, match it with the correct GKN Automotive replacement boot kit for proper fit and heat resistance. Confirm joint end and shaft end dimensions, along with front right outer or front left outer position, before installation on Mercedes-Benz GL350, GL450, GL550, ML350, ML450, ML550, ML63 AMG, GL320, ML320, or ML500 applications.

Quality Assurance

GKN Automotive supplies OE-quality driveline components and designs these boot kits to match the joint-specific fit required for reliable service on modern drivetrains. Part number 306112 is engineered for applications that originally used a TPE boot and should be selected to match the original configuration.
