Detailed Product Overview

This Elring differential seal is specified for Mercedes-Benz vehicles across a wide range of model years, including C-Class, E-Class, GLK, GLE, ML, SLK, and classic chassis applications. The seal dimensions and right-hand twist swirl type are important for matching the original sealing geometry, especially on inlet and rear positions where driveline fluid retention is critical. If you are replacing a leaking Mercedes-Benz differential seal, 152.940 provides the size and design details needed for a proper service match.

This part cross-references 025 997 00 47 and 34917 for the same application.

What This Seal Helps Address

• Differential fluid seepage at the inlet or rear sealing point
• Contamination entering the driveline sealing area
• Wear-related leakage from an aging radial shaft seal
• Noise or driveline service concerns caused by low fluid level
• Seal replacement needs on Mercedes-Benz rear axle and differential service

Installation Notes and Fitment Tips

Confirm the seal dimensions before installation: 40.0 mm inner diameter, 70.0 mm outer diameter, and 11 mm height. Match the swirl direction and radial shaft seal design to the original part, especially on Mercedes-Benz C300, E350, GLK350, and other listed applications. Clean the sealing surface thoroughly and inspect the shaft for wear or scoring before pressing in the new seal.
