Upper Ball Joint (Spring Tower)

Place jack under front crossmember and raise vehicle allowing wheel to drop to full down position. Attach dial indicator to upper control arm so that plunger rests against inner side of wheel rim. Check radial play by rocking wheel at top and bottom. Maximum allowable radial play on Maverick and Comet is 0.250", and on all other models there should be no perceptible looseness of upper ball joint. If wear exceeds specification, upper control arm should be replaced.
