Compression Rod
Removal and InstallationREMOVAL
1. Remove tires with power tool.
2. Remove undercover with power tool.
3. Remove cotter pin of compression rod ball joint, and loosen nut.
4. Use a ball joint remover (suitable tool) to remove compression rod from steering knuckle. Be careful not to damage ball joint boot.
CAUTION: Tighten temporarily mounting nut to prevent damage to threads and to prevent ball joint remover (SST) from coming off.
5. Remove compression rod and compression rod stay from vehicle.
INSPECTION AFTER REMOVAL
Visual Inspection
^ Check compression rod and bushing for deformation, cracks, or damage. If any non-standard condition is found, replace it.
^ Check boot of ball joint for cracks, or other damage, and also for grease leakage. If any non-standard condition is found, replace it.
Ball Joint Inspection
^ Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE: Before measurement, move ball joint at least ten times by hand to check for smooth movement.
^ Hook spring scale at ball stud. Confirm spring scale measurement value is within the specifications when ball stud begins moving.
Standard value
Swing torque: 0.147 - 2.45 Nm (0.02 - 0.24 kg-m, 2 - 21 inch lbs.)
Measured value of spring scale: 2.37 - 39.5 N (0.24 - 4.03 kg, 0.53 - 8.88 lb)
^ If it is outside the specified range, replace compression rod assembly.
Rotating Torque Inspection
^ Attach mounting nut to ball stud. Check that rotating torque is within the specifications with a preload gauge (SST).
Standard value
Rotating torque: 0.147 - 2.45 Nm (0.02 - 0.24 kg-m, 2 - 21 inch lbs.)
^ If it is outside the specified range, replace compression rod 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 compression rod assembly.
INSTALLATION
^ Refer to FSU-26, 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 Installation position between front suspension member and compression rod stay (rubber bushing) under unladen condition with tires on ground. Check wheel alignment.
