Detailed Description
This CV joint kit is engineered for front axle service on Mercedes-Benz S-Class vehicles where precise articulation and smooth torque transfer are required. The GKN Loebro Countertrack SX design is built around a characteristic S-shaped track profile and opposed tracks, helping reduce internal friction and heat while increasing transmissible torque and maximum bending angle. The result is a driveline service part that follows OE technology principles for consistent operation in demanding front outer applications.
This part cross-references FEL-PRO 36102 for the same application. Part number 306281 is also associated with Mercedes-Benz front outer and front right outer service needs across select S450, S560, S63 AMG, Maybach S550, and Maybach S560 models.
What It Helps Solve
- Clicking or popping during turns from a worn outer CV joint
- Vibration or shudder under acceleration from driveline wear
- Grease leakage caused by joint or boot deterioration
- Excessive play in the front axle joint assembly
- Reduced smoothness in steering and power delivery
Installation Notes and Tips
Verify spline count, joint diameter, thread size, and axle position before installation. Confirm whether the vehicle uses a front outer or front right outer application, since fitment varies by model year. Inspect the mating axle components for wear, contamination, or damage before assembly so the replacement joint can seat correctly and operate smoothly.
Quality Assurance
GKN Automotive is recognized for OE driveline technology used by major vehicle manufacturers, and Loebro Countertrack SX joints are built to the same engineering approach. Part number 306281 is a standard replacement CV joint kit for Mercedes-Benz driveline service.
