Detailed Description

The Cardone 66-2143 CV axle assembly is designed for Ford Focus front left applications where a worn axle can cause clicking, vibration, grease leakage, or ABS warning concerns. Cardone engineers these CV drive axles with attention to the common causes of repeat failure, including boot cracking, shaft runout, and seal wear. The result is a replacement axle built to support consistent driveline operation in daily driving conditions.

This part cross-references Ford OE numbers 2M5Z3B437CA and 5S4Z3B437AA for the same application.

What It Helps Fix
