SERVICE PROCEDURE

1. Raise the vehicle on a hoist, then carefully lower it and support the front of the vehicle with jack stands placed under the left and right lower control arms, at the outermost position.

2. Ensure that the front and rear wheels are straight.

3. Lower Ball Joint Measurement:





a. Attach a dial gauge and stand to the lower control arm. Position the dial gauge parallel to the lower ball joint assembly, with the gauge touching the tip of the threaded portion of the ball joint stud. See Figure 1.





b. Place a lever under the front tire of the wheel being measured (Figure 2).


c. While pressing on the lever under the tire, note any movement on the dial gauge. Ensure that the lower control arm does not move during this step.

d. If the dial gauge measurement is more than 1.8 mm, replace the lower ball joint as described in the appropriate Workshop Manual.





4. Upper Ball Joint Measurement (Figure 3):


a. Remove the tire and wheel assembly.

b. Position the dial gauge parallel to the upper ball joint assembly. Position a dial gauge stand (magnetic style recommended) on the upper portion of the knuckle, with the tip of the gauge touching top of the ball joint or one of its mounting bolts.

c. Using a large C-clamp, carefully compress the upper ball joint assembly and note any movement on the dial gauge.

d. If the dial gauge measurement is more than 2.0 mm, replace the upper ball joint as described in the appropriate Workshop Manual.
