UPPER BALL JOINT AND LOWER BALL JOINT

PFP:40110

Removal and Installation

EES00230

The ball joints are part of the upper and lower links. Refer to

FSU-13, "Removal and Installation"

(upper link),

FSU-14, "Removal and Installation"

(lower link).

Inspection

EES00231

●

Check the ball joint for excessive play. Replace the upper or lower link assembly if any of the following
exists:

–

Ball joint stud is worn.

–

Ball joint is hard to swing.

–

Ball joint play in axial directions or end play is excessive.

SWINGING FORCE

NOTE:
Before checking the axial forces and end play, turn the lower ball joint at least 10 revolutions so that the ball
joint is properly broken in.

1.

Measure the ball joint swinging force using a suitable tool.

●

Measure at the cotter pin hole for upper ball joint as shown.

●

Measure at the groove for lower ball joint as shown.

2.

Verify the ball joint swinging force is within specification.

TURNING FORCE

NOTE:
Before checking the axial forces and end play, turn the lower ball joint at least 10 revolutions so that the ball
joint is properly broken in.
