REMOVAL
1. Remove tire with power tool.
2. Remove stabilizer connecting rod mounting bracket from suspension arm with power tool.
3. Remove drive shaft from vehicle. (VK45DE models) Refer to Removal and Installation.
4. Remove cotter pin of suspension arm ball joint, and loosen nut.
5. 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.

6. Remove fixing nuts and bolts between suspension arm and rear suspension member with power tool.
7. Remove suspension arm from vehicle.

INSPECTION AFTER REMOVAL
Visual Inspection
^ Check suspension arm and bushing for deformation, cracks, or damage. If any nonstandard condition is found, replace it.
^ Check boot of ball joint for cracks, or damage, and also for grease leakage.

Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.

Swing Torque Inspection

NOTE: Before measuring, move ball joint at least ten times by hand to check for smooth movement.





^ Hook a spring scale at cotter pin mounting hole. Confirm spring scale measurement value is within the specifications when ball stud begins moving.
Swing torque: 0.5 - 3.4 Nm (0.06 - 0.34 kg-m, 5 - 30 inch lbs.)
Measured value of spring scale: 9.7 - 66.0 N (0.99 - 6.7 kg, 2.18 - 14.8 lbs.)
^ If it is outside the specified range, replace suspension arm assembly.

Rotating Torque Inspection





Attach mounting nut to ball stud. Make sure rotating torque is within the specifications with a preload gauge (SST).
Rotating torque: 0.5 - 3.4 Nm (0.06 - 0.34 kg-m, 5 - 30 inch lbs.)
^ If it is outside the specified range, replace suspension arm assembly.

Axial End Play Inspection
Move tip of ball joint in axial direction to check for looseness.
Axial end play: 0 mm (0 inch)
^ If it is outside the specified range, replace suspension arm assembly.

INSTALLATION
^ Refer to Components for tightening torque. Install in the reverse order of removal.

NOTE: Refer to component parts location and do not reuse nonreusable parts.

^ Perform final tightening of rear suspension member installation position (rubber bushing) under unladen conditions with tires on level ground. Check wheel alignment. Refer to Wheel Alignment Inspection.

After adjusting wheel alignment, adjust neutral position of steering angle sensor.
