Suspension Arm

SUSPENSION ARM


Removal and Installation


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.






Standard value
Swing torque: 0.5 - 3.4 N�m (0.06 - 0.34 kg-m, 5 - 30 in-lb)
Measured value of spring balance: 8.1 - 54.8 N (0.83 - 5.5 kg, 1.82 - 12.32 lb)

- 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)






Standard value
Rotating torque: 0.5 - 3.4 N�m (0.06 - 0.34 kg-m, 5 - 30 in-lb)

- 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.

Standard value
Axial end play : 0 mm (0 in)

- If it is outside the specified range, replace suspension arm assembly.

INSTALLATION
- Installation is the reverse order of removal. For tightening torque. Refer to Component.

CAUTION:
Do not reuse non-reusable parts.
- Perform the final tightening of rear suspension member installation position (rubber bushing) under unladen condition with tires on level ground. Refer to Rear Suspension Assembly.
- Adjust neutral position of steering angle sensor after checking the wheel alignment. Refer to Testing and Inspection.
