1. Raise and support the vehicle.
2. Support the vehicle with suitable jackstands under the axle.
3. Remove the tire and wheel assemblies. Refer to WHEEL REMOVAL.
4. If removing the right bushings, disconnect the brake lines from the body. If removing the left bushings, disconnect the brake line bracket from the body and the parking brake cable from the hook guide on the body.
NOTICE: Do not suspend rear axle by brake hoses. Damage to hoses could result.
5. Remove the nut, bolt, and washer from the control arm and underbody attachment. Rotate the control arm downward. (Remove and install one control arm bushing at a time.)
6. Remove the bushing using the following procedure:
6.1. Install the J 29376-2 into the slot in the control arm.
6.2. Position the J 29376-1 over the control arm end/bushing.
6.3. Install the J hooks through the J 29376-1 and J 29376-2 tighten the attaching nuts until the tool is securely in place.
6.4. Install the J 21474-19 bolt through the plate J 29376-7 and install into the J 29376-1.
6.5. Place the J 29376-6A remover into position on the bushing.
6.6. Install the nut J 21474-18 onto the J 21474-19 bolt.
6.7. Remove the bushing from the control arm by turning the bolt.
INSTALLATION PROCEDURE
1. Install the bushing as follows:
1.1. Install the J 29376 receiver on the control arm.
1.2. Install the J 21474-19 bolt through the J 29376-A plate and into the receiver.
1.3. Install the bushing on the bolt and position into the housing. Align the bushing installer arrow with the arrow on the receiver for proper indexing of the bushing. A high-pressure lubricant such as J 23444-A may be necessary for assembly.
1.4. Install J 21474-18 (3/8 in) nut onto the J 21474-19 (3/8 in) bolt.
1.5. Press the bushing into the control arm by turning the bolt. When the bushing is in the proper position, the end flange will be flush against the face of the control arm.
Important: The washer and nut must be installed on the outboard side.
2. Align the control arm and the underbody attachment.
3. Loosely install the bolt, the washer, and the nut.
4. Install the left and right brake pipe brackets and the attaching screws.
Tighten
Tighten the screws to 11 Nm (97 inch lbs.).
NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.
5. Install the tire and the wheel assemblies. Refer to WHEEL INSTALLATION.
6. Remove the jackstands and lower the vehicle to curb height.
Tighten
Tighten the control arm nuts to 80 Nm (59 ft. lbs.), plus 120° rotation using J 36660.
