Removal and Installation

REMOVAL
1. Remove tire with power tool.
2. Remove drive shaft.
3. Remove fixing nuts and bolts between suspension arm and rear suspension member.
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 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.

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 spring scale at cotter pin mounting hole. Confirm spring scale measurement value is within specifications when ball stud begins moving.
Standard value Swing torque: 0.5 - 3.4 Nm (0.06 - 0.34 kg-m, 5 - 30 inch lbs.)
Measured value of spring scale: 8.06 - 54.8 N (0.83 - 5.5 kg, 1.81 - 12.32 lbs.)
^ If it is outside the specified range, replace suspension arm assembly.

Rotating Torque Inspection





^ Attach mounting nut to ball stud. Make sure that sliding torque is within the specifications with a preload gauge (SST).
Standard value
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.
Standard value
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 non-reusable parts.

^ Perform final tightening of rear suspension member installation position (rubber bushing) under unladen condition with tires on level ground. Check wheel alignment.
