REMOVAL
1.
Remove tire with a power tool.
2.
Set a jack under rear lower link to relieve the coil spring tension.
3.
Remove connecting rod mounting bracket from suspension arm with a power tool.
4.
Remove mounting nuts and bolts between suspension arm and rear suspension member.
5.
Remove cotter pin of suspension arm ball joint, and loosen nut.
6.
Use a ball joint remover (suitable tool) to remove suspension arm from axle. Be careful not to damage ball
joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to threads and to prevent ball joint remover
(suitable tool) from coming off.
7.
Remove suspension arm and stopper rubber from vehicle.
INSPECTION AFTER REMOVAL
Visual Inspection
●
Check suspension arm and bushing for deformation, cracks or damage. If any non-standard condition is
found, replace it.
●
Check boot of ball joint for cracks or damage, and also for grease leakage. If a malfunction is detected,
replace suspension arm.
Ball Joint Inspection
Manually move ball stud at least ten times by hand to check for smooth movement.
Swing Torque Inspection
●
Hook spring balance at cotter pin mounting hole. Confirm spring
balance measurement value is within specifications when ball
stud begins moving.
●
If it is outside the specified range, replace suspension arm
assembly.
Rotating Torque Inspection
●
Install the mounting nut to ball stud. Make sure that rotating
torque is within the specifications with a preload gauge (SST)
●
If it is outside the specified range, replace suspension arm
assembly.
Axial End Play Inspection
●
Move tip of ball stud in axial direction to check for looseness.
