Product Details

Cardone’s CV axle assembly line is built around failure analysis and remanufacturing engineering that addresses common causes of CV joint wear, including boot cracking, contamination, and shaft runout. The axle shaft is inspected for straightness, and the transmission seal diameter is precision-machined after heat treatment to support proper sealing and consistent fit. This part number, 66-2101, is a practical replacement for front left driveline service on the Ford Explorer, Ford Ranger, Mazda B2300, Mazda B3000, Mazda B4000, and Mercury Mountaineer listed below.

This part cross-references Ford (e.g., F5TZ3B436A, F57Z3B437BA) for the same application.
