Lower Control Arm Replacement With B9Q/V4U

1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the tire and wheel. Refer to Tire and Wheel Removal and Installation in Tire and Wheels.
3. Remove the road sensing suspension position sensor from the lower control arm.
4. Separate the ball joint from the lower control arm. Refer to Lower Control Arm Ball Joint Replacement With V4U/B9Q.
5. Remove the lower control arm bushing bolt, brake reaction rod nut, retainer and insulator.
6. Remove the lower control arm from frame.

1. Install the lower control arm to the frame.
2. Install the lower control arm bushing bolt, brake reaction rod nut, retainer and insulator. Do not tighten at this time.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the ball joint to the steering knuckle.

Tighten
Tighten the ball joint nut to 175 N·m (129 lb ft).

4. Install the road sensing suspension position sensor to the lower control arm.
5. Instal the tire and wheel assembly.

Tighten
Tighten the wheel nuts to 140 N·m (100 lb ft).

6. Lower the vehicle and allow the vehicle to assume proper trim height.

Tighten

•	Tighten the control arm bushing nut to 126 N·m (94 lb ft).

•	Tighten the control arm bushing horizontal bolt to 157 N·m (116 lb ft).

•	Tighten the brake reaction rod nut to 126 N·m (116 lb ft).

Lower Control Arm Replacement Without B9Q/V4U

Tools Required

1. Raise the vehicle and support the frame with jack stands. Refer to Lifting and Jacking the Vehicle in General Information.

Notice: Care must be exercised to prevent Tri-Pot joints from being over-extended. When either end of the shaft is disconnected, over-extension of the joint could result in separation of internal components and possible joint failure. Drive axle joint seal protectors should be used any time service is performed on or near the drive axles. Failure to observe this can result in interior joint or seal damage and possible joint failures.

2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
3. Remove the Road Sensing Suspension position sensor from the lower control arm.



4. Separate the lower ball joint from the steering knuckle using the J 35315 Ball Stud Separator.
5. Push the strut knuckle assembly rearward.
6. On the left control arm, support the transaxle with a screw jack and a wood block.

6.1.	Remove the two transaxle mount nuts.

6.2.	Raise the transaxle with the screw jack to access the control arm bolt.

7. Remove the control arm forward and rearward nut and bolts.
8. Remove the control arm from the frame.

1. Install the control arm to the frame.
2. Install the control arm forward and rear attachment. Do not tighten.
3. Install the transaxle mount in position and lower the transaxle. Remove the screw jack.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Install the lower ball joint to the knuckle.

Tighten
Tighten the ball joint nut to 10 N·m (84 lb in) using the J 35551 Ball Stud Nut Wrench 90 degrees to the torque wrench. Tighten the nut and additional 120 degrees. When tightening the nut a minimum torque of 50 N·m (37 lb ft) must be obtained. If 50 N·m (37 lb ft) is not obtained, inspect the nut for stripped threads. If the threads are satisfactory, replace the ball joint and the knuckle. If required, turn the nut up an additional 60 degrees in order to allow for the installation of the cotter pin.

5. Install the Road Sensing Suspension position sensor to the lower control arm.
6. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.

Tighten
Tighten the wheel nuts to 140 N·m (100 lb ft).

7. Lower the vehicle and allow the vehicle in order to assume proper trim heights.

Tighten

•	Tighten the control arm rear bolt to nut to 157 N·m (116 lb ft).

•	Tighten the control arm forward bolt to nut to 126 N·m (93 lb ft).
