Detailed Description

MOOG K80149 is engineered as a front lower suspension ball joint for the Ford F-150, Ford Expedition, and Lincoln Mark LT. The design uses a powdered-metal gusher bearing to help grease reach bearing surfaces, while the pre-installed integral dust boot supports easier installation and helps protect the joint during service. This part cross-references Dorman OE Solutions 536-242 for the same application.
