TrakMotive MB-8078 CV Axle Shaft - Front Left

Mercedes-Benz Front Left CV Axle Shaft

TrakMotive MB-8078 is a new front left CV axle shaft for select Mercedes-Benz applications, including GLC63 AMG, E-Class, CLS450, and related models. It is built with a neoprene boot and application-specific spline counts for a direct driveline replacement.

The TrakMotive AAR CV Axle Shaft line focuses on replacement axles for modern European drivetrains. MB-8078 follows that approach with OE-style fitment details, including a female inboard joint, Audi-style spline bolt outboard joint, and compressed length of 20.43 in. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

• Female inboard joint with spline connection style
• Audi-style spline bolt outboard joint design

Detailed Description

TrakMotive MB-8078 is a front left CV axle shaft engineered for Mercedes-Benz driveline service where the original axle has worn joints, torn boots, or spline wear. It is listed for 2021 Mercedes-Benz GLC63 AMG and GLC63 AMG S, 2020 Mercedes-Benz CLS450, E350, E450, E63 AMG S, and 2017-2019 Mercedes-Benz E300, E400, and E63 AMG S applications, along with select updated-design 213 Type and 253 Type vehicles. Use the exact fitment notes, including VIN 8J references where shown, to confirm application before ordering.

MB-8078 is part of TrakMotive’s AAR CV Axle Shaft line and is manufactured by an ISO 9001:1007 and TS 16949:2009 certified company. The axle is new, not remanufactured, and is built to match the specified spline and joint configuration for the listed Mercedes-Benz models.

What It Helps Fix

• Clicking or popping during turns from a worn CV joint
• Vibration under acceleration from axle shaft wear
• Grease leakage from a damaged axle boot
• Clunking or driveline noise from spline or joint wear
• Front left axle failure on listed Mercedes-Benz applications

Installation Notes and Tips

Confirm the vehicle’s VIN, chassis type, and fitment notes before installation, especially for 213 Type, 253 Type, 257 Type, and VIN 8J applications. When replacing a CV axle on the 2020 Mercedes-Benz E63 AMG S, inspect the intermediate shaft for damage and replace it if necessary. Verify spline counts, joint style, and compressed length against the original part before assembly.

Quality Assurance

TrakMotive identifies MB-8078 as a new replacement axle backed by a limited lifetime warranty. The manufacturer also states that ABS axles fit non-ABS applications unless otherwise noted, and that its production is supported by ISO 9001:1007 and TS 16949:2009 certification.
