      I used e Driveworks ball joint previously, they lasted four years, but the Moog with the grease fitting lasted eight years and counting on my Ford Excursion, so the Lincoln is getting Moog now too!

        Comments about MOOG Ball Joint:

        These ball joints are much better than the stock units. They have fine threads, a grease fitting, a castle nut w/ cotter pin, and a larger bottom end. the original has none of these. The moog ball joint fit perfectly. I replaced both bottom ball joints. My only complaint is that Advance charges too much for their parts.

          easy to use but you will need a press to install.
          check each box of your order to insure all parts are in the box.

                      A:

                      With reference to your inquiry on the Moog Ball Joint -part# K8685, for replacing the lower ball joints on a Grand Marquis, raise the car's front end with a floor jack and then support this end on jack stands. Remove the front wheel (using the car's tire iron) that corresponds with the ball joint that needs changing. Remove the mounting nuts for the shock absorber with a wrench. Remove the mounting bolts for the brake caliper with a wrench and remove the caliper--hang it by a strong wire so it won't stretch its hose--and then slip the brake disc off. Remove the upper and lower stabiliser bar links by removing their nuts. Remove the upper ball joint nut for the pinch bolt with your wrench and separate the control arm from the steering knuckle with a pry bar. Remove the shock absorber's lower bolt and remove the assembly from the car. Remove the cottar pin from the ball joint stud and then loosen the stud's castle nut by one or two turns with a wrench. Tap the knuckle sharply with a hammer near the stud and loosen the stud within the knuckle. Remove the ball joint stud nut with a wrench, followed by the lower control arm's mounting bolts and then remove the control arm. Take the lower control arm to an automotive machine shop that can remove the ball joint from the control arm and install a new one. Connect the lower control arm to the steering knuckle with its mounting bolts. Connect the bolts without tightening them for now. Connect the ball joint to the steering knuckle using its stud and tighten the castle nut with the wrench, making sure the nut's slot is in line with the hole in the stud. Insert a new cottar pin in the hole and slot. Reinstall the shock absorber assembly using its nuts and your wrench, followed by the stabiliser bar links, the brake disc and the brake caliper. Reconnect the control arm to the steering knuckle using the pinch bolt and its upper ball joint nut. Raise a floor jack underneath the lower control arm to lift the arm to the car's normal ride height, then tighten the control arm's pivot nut bolts. Reconnect the wheel and lower the car off the jack stands. For any further assistance, please visit your nearest Advance Auto store or call us directly at 1-877-ADVANCE (238-2623) and one of our representatives there would be more than happy to assist you.

                  • Q:

                    On a 1995 Mercury Grand Marquis, is it necessary to replace the lower ones, or can you just replace the upper, thanks.

                      It is always better to replace both the lower and upper ones.
