Product Details

Cardone engineers its CV drive axles around common failure points found in original units, including boot cracking, seal wear, and vibration from shaft runout. The shaft is individually checked for straightness to help maintain vibration-free performance at speed, while the precision-machined transmission seal diameter supports proper sealing and long seal life. This makes 66-2159 a practical replacement for a worn rear right axle on the Ford Expedition.

This part cross-references Ford OE numbers 3L1Z4K138BA and 4L1Z4K138A for the same application.
