Detailed Product Information

This GKN Loebro CV joint boot kit is engineered for exact-fit replacement on Mercedes-Benz front outer driveline positions. The TPE construction is important on vehicles that generate higher joint temperatures, since the material is used to handle elevated heat while maintaining a reliable seal. If the original driveshaft uses a TPE boot, matching the replacement material is the correct service choice.

Part number 306618 is listed for 2014-2023 Mercedes-Benz applications, including 2020-2023 C300 and C43 AMG, 2020-2022 GLC300 and GLC43 AMG, and 2014-2019 S63 AMG. It also covers front right outer and front left outer positions on select Mercedes-Benz C300, S450, S560, and Maybach models. This makes 306618 a direct-fit service part for common Mercedes-Benz CV boot repair needs.

What It Helps Repair

• Torn CV boot material that exposes the joint to dirt and moisture
• Slipped boot sealing that allows grease loss
• Porous or aged boot material that no longer protects the joint
• Front outer CV joint contamination on Mercedes-Benz driveline assemblies
• Noise or wear concerns caused by loss of boot protection

Installation Notes and Tips

Confirm the exact Mercedes-Benz model, year, and front outer position before installation. Match the original boot type and dimensions, especially when replacing a factory TPE boot. Inspect the CV joint for contamination or wear before fitting the new boot, and verify the axle end and joint end diameters against the original part.
