Lower

^ Tool Required:
- J 8001 Dial Indicator





Make sure the vehicle rests on a level surface.
Raise the vehicle and support it with safety stands. Support the lower control arm with a floor stand or jack as far outboard as possible under the stabilizer bar bracket.

Important
- The vehicle must be stable and should not rock on the floor stands.
- The upper control arm bumper must not contact the frame.

1. Wipe the ball joints clean and check the seals for cuts or tears.
- If a seal is cut or torn, the ball joint MUST be replaced.
2. Check the ball joints for horizontal looseness.
a. Position a dial indicator against the lowest outboard point on the wheel rim.
b. Rock the wheel in and out while reading the dial indicator. This will show horizontal looseness in both joints.
c. The dial indicator reading should be no more than 3.18 mm (0.125 inch). If the reading is excessive, check the lower ball joints for vertical looseness.





3. Check the lower ball joints for wear and vertical looseness.
a. With the vehicle on the jack stands, place a (A) dial indicator against the spindle to show vertical movement.





b. Pry between the (B) lower control arm and the (A) outer bearing race while reading the dial indicator. This will show vertical looseness in the ball joints.
c. The lower ball joint is not a pre-loaded ball joint and may show some looseness.

Important: Do not pry between the lower control arm and drive axle seal. Damage to the seal will result.

- If the dial indicator reading is more than 3.18 mm (0.125 inch), replace the ball joint.

4. If the lower ball joint is within specifications and horizontal looseness is excessive, check the upper ball joint for wear.
a. Disconnect the ball joint from the knuckle.
b. If any looseness is found, or the stud can be twisted with your fingers, replace the ball joint.
