Detailed Description

GKN Loebro 306102 is engineered as a direct-fit CV joint boot kit for front right outer and front left outer positions on BMW X5 and BMW X6 driveline assemblies. The TPE material is used on many original driveline applications because it handles elevated operating temperatures and helps maintain boot integrity under torque load. If the original driveshaft uses a TPE boot, matching the replacement material and fit is important for proper service.

This part cross-references BMW 31607545108 for the same application. The GKN Loebro 306102 boot kit is intended for BMW X5 front outer and BMW X6 front outer service where the original boot has failed or shown wear.

Common Problems This Part Addresses

• Torn CV boot causing grease loss
• Slipped boot that no longer seals the joint
• Porous or cracked boot material
• Contamination entering the CV joint
• Noise or vibration related to boot failure and joint wear

Installation Notes and Tips

Confirm the joint end and shaft end dimensions before installation to ensure exact fit. This boot kit is for solid TPE boot replacement on the specified BMW X5 and BMW X6 front outer positions. Inspect the CV joint for damage before installing a new boot, since a failed boot can allow grease loss and contamination that may affect joint condition.

Use the original application details to verify whether the vehicle requires a TPE replacement boot. For BMW X5 and BMW X6 service, matching the boot material and dimensions is critical to restoring proper sealing performance.
