Step 5

If there are following conditions, replace the ball joint.

(a)

Ball joint loose.

(b)

Ball joint seal broken.

(c)

Ball stud and steering knuckle disconnected.

(d)

Ball stud loose in the steering knuckle.

(e)

Press the ball stud, it twists.

Step 6

Components normal.

4.2.6.4 Ball Stud Inspection

During each inspection, check whether the ball stud is tightly installed in the steering knuckle.

Check whether the ball stud is worn:

A. Shake the wheel and the ball stud or nut movement in the steering knuckle.

B. Check slotted nut fastening torque. Nut loose indicates that ball joint withstands stress or there is a hole in the steering knuckle.

Replace  the  worn  or  damaged  ball  joint  or  steering  knuckle.  Refer  to

4.2.6.5 Friction Too Great Inspection

Follow the procedures to check whether the front suspension friction is too great:

Step 1

Raise the front bumper and lift the vehicle as high as possible.

Next

Step 2

Slowly lower down the bumper for the vehicle front end to resume its height.

Next

Step 3

Measure the distance between the ground and the bumper center.

Next

Step 4

Push the bumper and then slowly release to allow the vehicle to resume its height.

Next

Step 5

Measure the distance between the ground and the bumper center.

Next

Step 6

The two measured values difference should be less than 12.7 mm (0.5 in). If the distance exceeds this limit,
check the control arm, shock absorber and ball joint for damage or wear and tear.
