^ Tools Required:
- J 21474-5 Control Arm Bushing Receiver
- J 21474-18 Upper Control Arm Nut
- J 21474-19 Upper Control Arm Screw
- J 39872 Half Moon Spacer
- J 39930 Upper Control Arm Bushing Receiver/Installer
- Or Equivalents

DISASSEMBLE
1. Upper control arm. Refer to "Front Upper Control Arm".
2. Remove bolts/screws (37) and nuts (38).
3. Separate front upper control arm (1) from front upper control arm support (46).
4. Remove upper control arm bushing from upper control arm (1).
A. Thread J 21474-19 through J 39930 (three tangs on J 39930 should be against head of screw).
B. Thread J 21474-19 through inside of upper control arm bushing (it may be necessary to wiggle J 21474-19 until it slides through bushing.
C. Run smaller end of J 21474-5 onto J 21474-19. Then, place thrust washer onto J 21474-19 with seams facing toward J 21474-5.
D. Install J 39872 around outside of bushing to avoid metal distortion during removal.
E. Make sure both J 39930 and J 21474-5 are properly lined up and install J 21474-18 onto J 21474-19. Tighten J 21474-19 and J 21474-18 until bushing is pushed all the way out (popping noise may be heard when bushing breaks loose from control arm).

ASSEMBLE

NOTICE: Always use the correct fastener in the correct 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 the 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.
