- TOOLS REQUIRED
- SA9411C Front Lateral Link Installer
- SA9155S Strut Spring Compressor
- SA9140E Torque Angle Gauge
- SA91107NE Wheel Stud Remover


REMOVAL

1. Remove rear window trim finish panel.

CAUTION: MAKE SURE VEHICLE IS PROPERLY SUPPORTED AND SQUARELY POSITIONED ON HOIST. TO HELP AVOID PERSONAL INJURY, PROVIDE ADDITIONAL SUPPORT TO THE OPPOSITE END OF THE VEHICLE THAT COMPONENTS WILL BE REMOVED FROM.





2. Raise vehicle on hoist.
3. Remove wheels corresponding to strut being replaced.
4. Loosen the two strut-to-knuckle fasteners. Leave fasteners in place.
5. Lower vehicle to a level that a floor jack can be placed under the rear knuckle. Raise floor jack high enough to support the knuckle.





6. Remove and discard the three strut assembly-to-body attachment nuts.
7. Slowly raise hoist, lowering strut assembly from the body.





8. Remove the two strut-to-knuckle fasteners.
9. Remove strut assembly from vehicle.

DISASSEMBLY

CAUTION: STRUT SPRING IS UNDER A HIGH COMPRESSIVE LOAD. DO NOT REMOVE THE STRUT SHAFT TO UPPER SUPPORT NUT WITHOUT FIRST RELIEVING THE UPPER AND LOWER SPRING SUPPORTS OF SPRING PRESSURE, USING THE PROPER SPRING COMPRESSING TOOL.





1. Mount strut spring compressor SA9155S (or equivalent) in holding fixture.
2. Place strut/spring assembly into spring compressor. Fasten strut with a strut-to-knuckle bolt and nut through the lower strut mounting hole.
3. Compress spring enough to completely unload the upper spring supports.





4. Remove strut shaft nut using a wrench, while holding the shaft with a TORX socket.





5. Release spring compressor and tilt strut assembly outward.
6. Remove upper spring support. Inspect rubber for cracks or deterioration.
7. Remove spring from strut. Inspect spring for damage.
8. Remove dust shield assembly. Inspect for cracks or deterioration.
9. Remove strut from compressor. Extend and retract strut shaft and check for smooth, even resistance.

ASSEMBLY

1. Place strut into spring compressor. Fasten strut with a strut-to-knuckle bolt and nut through the lower strut mounting hole. Extend strut shaft to the limit of its travel.





3. Place dust shield assembly onto strut assembly.
4. Install spring onto strut.
5. Install upper strut mount onto strut and spring.

IMPORTANT: Make sure that the springs are correctly positioned in their spring support seats.





6. Compress the spring, guiding the strut shaft through upper mount until the upper washer and shaft nut can be installed. Do not over compress the spring.
7. Tighten strut shaft using a TORX socket, while holding the shaft nut with a wrench.
Torque: 50 Nm (37 ft. lbs.)
8. Release spring compressor tool.
9. Remove strut from compressor.

INSTALLATION

NOTICE: Use new nuts; torque retention of old nuts may not be sufficient.

IMPORTANT: Install strut to the vehicle body and hold in place with strut-to-knuckle bolts. This will facilitate installing the three upper support-to-body attachment fasteners.





1. Attach strut to the vehicle body with the three upper support-to-body attachment nuts.
Torque: 29 Nm (21 ft. lbs.)

IMPORTANT: With strut-to-knuckle fasteners installed but not tightened, push bottom of strut inward while tightening fasteners.

NOTICE: Use new nuts; torque retention of old nuts may not be sufficient.

2. Attach strut-to-knuckle with fasteners.
Torque: 170 Nm (126 ft. lbs.)

NOTICE: Before installing wheels, remove rust or corrosion from wheel mounting surfaces and brake rotors/drums. Failure to do so can cause wheel nuts to loosen in service.

3. Position wheel onto hub.
4. Install wheel nuts and tighten in a crisscross pattern. Repeat tightening pattern to make sure torque is correct.
Torque: 140 Nm (103 ft. lbs.)
5. Lower vehicle from hoist.
6. Install rear window trim finish panel.
7. Perform vehicle wheel alignment.
