Keep the front suspension properly located and let the steering knuckle pivot smoothly with the Mevotech Supreme Front Upper Ball Joint MK8678. This ball joint drops in as a direct-fit replacement for the 1995-2002 Ford Crown Victoria, 1995-2002 Lincoln Town Car and 1995-2002 Mercury Grand Marquis (see the "Vehicles it fits" section for engine-level details). Mevotech Supreme ball joints are engineered in-house with application-specific upgrades for increased durability.
- Fasteners included: installs faster with the application-specific pinch bolt and locking nut provided.
- Simple to service: re-greasing is a snap thanks to the included 90-degree SAE grease fitting.
- Resists corrosion: a protective surface treatment helps limit rust build-up.
- Keeps water and debris out: the pre-installed dust boot shields the internal components from contaminants.
This front upper joint connects the upper control arm to the steering knuckle, allowing controlled suspension travel while the wheel steers. Clunking or popping over bumps, wandering steering and uneven tire wear are signs the original may need replacing—if a worn ball joint is the cause, this replaces it. Extensive in-house and third-party durability testing backs its strength.
