Dorman - OE Solutions Suspension Ball Joint P/N:540-043
The Dorman ball joint 540-028 is a front lower pivot that links the lower control arm to the steering knuckle, letting the wheel steer and travel with the suspension. It fits many vehicles, among them the 1995-2002 Ford Crown Victoria, 1995-2002 Mercury Grand Marquis and 1995-2002 Lincoln Town Car.
Dorman OE Solutions designed and tested this joint to take the place of the original equipment on the listed applications:
A lower ball joint carries steering and suspension movement at the knuckle, so wear shows up as play in the front end. Signs it may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, and noticeable movement at the joint when the wheel is checked. Inspect the front end to confirm the cause before replacing parts. Whether you need a 1995-2002 Ford Crown Victoria ball joint or a 1995-2002 Lincoln Town Car ball joint, see the Buyer's Guide tab for the complete application list.
