Keep the rear suspension tight and precise with the MOOG Chassis Products Rear Upper Suspension Ball Joint K500109. It installs as a direct-fit replacement for the 2002-2005 Ford Explorer, 2003-2005 Lincoln Aviator, and 2002-2005 Mercury Mountaineer, pivoting the rear upper suspension connection so the wheel can move through its travel while maintaining proper geometry.
Gusher Bearing design: a metal-to-metal Problem Solver bearing built for strength that lets grease flow across the bearing surface to reduce friction.
Greaseable socket: new lubricant can flush out contaminants to help limit corrosion and wear.
Heat-treated ball stud: processed to match or exceed OE requirements for improved fatigue strength and to help inhibit premature failure.
Belleville preload washer & pressed-in cover plate: helps keep the bearing package tight as it wears, while the patented cover plate seals out debris to reduce looseness.
Precision tolerances are designed for straightforward installation and steering alignment. If a worn rear upper ball joint is the cause of clunking, looseness, or uneven tire wear, this replaces it.
It fits the 2002-2005 Ford Explorer, 2003-2005 Lincoln Aviator, and 2002-2005 Mercury Mountaineer. Check the Buyer's Guide tab to confirm the fit for your vehicle.
