Tools Required

Service the upper control arm bushing separately from the upper control arm.

1. Remove the upper control arm. Refer to Upper Control Arm Replacement .
2. Remove the bolts/screws and the nuts.
3. Separate the front upper control arm from the upper control arm support.



4. Perform the following procedure in order to remove the upper control arm bushing from the upper control arm (2):

4.1.	Thread J 21474-19 through J 39930 (the three tangs on J 39930 should be against the screw head).

4.2.	Thread J 21474-19 through the inside of the upper control arm bushing (you may need to wiggle J 21474-19 until the tool slides through the bushing).

4.3.	Run the smaller end of J 21474-5 onto J 21474-19 , then place the thrust washer (1) on J 21474-19 with the seams facing toward J 21474-5 .

4.4.	Install J 39872 around the outside of the bushing in order to avoid metal distortion during removal.

4.5.	Ensure that both J 39930 and J 21474-5 line up properly, then install J 21474-18 on J 21474-19 .

4.6.	Tighten J 21474-19 and J 21474-18 until the bushing is pushed all the way out (making a popping noise).

1. Perform the following procedure in order to install the upper control arm bushings:

1.1.	Secure the control arm tightly in a vise, then thread J 21474-19 through J 39930 (the three tangs on J 39930 should face away from the screw head).

1.2.	Install a new upper control arm bushing onto J 21474-19 with the three indentations facing toward the three tangs on J 39930 .

1.3.	Install the threaded end of J 21474-19 into the upper control arm from the outer side of the control arm.

1.4.	Install J 21474-5 onto J 21474-19 from the inside of the control arm.

1.5.	Install the thrust washer (2) onto J 21474-19 with the seam facing toward the control arm bushing.

1.6.	Install J 39872 around the outside of the bushing in order to avoid metal distortion during removal.

1.7.	Install J 21474-18 onto J 21474-19 , ensuring that the three tangs prongs on J 39930 fit into the indentations of the bushing.

1.8.	Tighten until the bushing is flush with the control arm.

2. Install the front upper control arm to the front upper control arm support.

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 bolts/screws and nuts.

Tighten
Tighten the nuts to 98 N·m (72 lb ft).

4. Install the upper control arm. Refer to Upper Control Arm Replacement .
