Product Details

Cardone engineers its CV Drive Axle assemblies to address common failure points found in original units, including boot cracking, contamination, and vibration from shaft runout. This rear right CV axle assembly is designed for 2009-2018 Ford Taurus, 2009-2016 Lincoln MKS, 2010-2013 Lincoln MKT, 2009-2012 Ford Flex, 2009 Ford Taurus X, and 2009 Mercury Sable applications, with a 2019 Ford Taurus rear right listing also shown in the fitment data. The Cardone 66-2246 uses precision-machined sealing surfaces after heat treatment and verified shaft straightness to support consistent driveline operation. This part cross-references Ford/Lincoln/Mercury OE number 8A8Z4K138A for the same application.
