Product Details

This TrakMotive CV axle shaft, part number MB-86040, is specified for rear applications on the Mercedes-Benz C230, C240, and C320 in the 203 Type platform. The assembly uses a conventional outboard joint, a male inboard joint, and thermoplastic boot material to support driveline articulation while maintaining a serviceable replacement format. The axle measures 28.81 inches compressed and 31.94 inches extended, which helps match the original installation envelope. MB-86040 is also identified by the same part number in interchange listings.

TrakMotive positions this CV axle shaft within its CV Axle Shaft product line for driveline service work where a complete axle assembly is needed. The included ABS tone ring and axle nut add key service details that matter during replacement, especially on applications that use ABS-equipped components. This part cross-references TrakMotive (e.g., MB-86040) for the same application.

Common Replacement Issues

• Clicking or popping from a worn CV joint.
• Vibration during acceleration from a damaged axle shaft.
• Torn boots that allow grease loss and contamination.
• ABS signal faults related to a worn tone ring.
• Loose or damaged axle hardware at the hub connection.

Installation Notes

Verify rear fitment by model and 203 Type application before installation. Confirm spline count, axle nut thread size, and ABS configuration against the original part. The manufacturer notes that ABS axles fit non-ABS applications unless otherwise noted, so application details should be checked carefully during service.

Quality Assurance

TrakMotive identifies this axle shaft as part of a company certified to ISO 9001:2008 and TS 16949:2009 standards. The product is backed by a limited lifetime warranty.
