Detailed Description

This InMotion WTA13 bearing is specified for manual transmission differential service and related front inner bearing locations across multiple vehicle platforms. It is a taper bearing set application in many listings, with cup and cone notes shown for numerous Ford F-150, Ford E-150, Ford Mustang, Jaguar XJS, and Mercury Cougar fitments. The dimensional profile helps identify the correct replacement when servicing drivetrain components that rely on precise bearing support and low-friction operation.
