Product Details
This page covers the Whiteline Front Lower Ball Joint for the 1987-1994 Mercury Grand Marquis GS. Part number W53557. It is listed for the Panther chassis. You receive 1 ball joint. Trim named on the listing: GS. This part is for the front of the vehicle. Application note: Standard Replacement.
The lower ball joint is the pivot between the control arm and the steering knuckle, and the wheel turns and moves up and down on it. When it wears, it develops play that shows up as clunks, wandering steering, and uneven tire wear. A new joint takes up that slack.
Installation is rated difficult, with about 1 hour of work listed. An alignment is required after installation.
Features
- Serviceable: A grease fitting lets the part be serviced later.
- Play removed: Takes out the slack of a worn original joint.
- Replacement joint: Restores steering precision and smooth articulation at the control arm.
- Geometry: Keeps alignment and geometry closer to where they should be.
- Durable build: Made from wear-resistant materials built for heavy loads and constant movement.
