Instructions

1. Secure the vehicle on a set of jack stands. Remove the wheel and access the control arm by removing the caliper and caliper bridge. Index the control arm bolts with a permanent marker to know where to tighten them on reinstallation. Place the lug nuts on a magnetic tray to avoid losing them.

2. Use a 1/2-inch drive socket wrench with a 22 mm socket to break loose the nut on the control arm mounting. Turn it counterclockwise until it is hand tight, then use your hand to continue unscrewing and remove the retaining nut. Put it on a magnetic tray or in your pocket to avoid losing it.

3. Remove the cam adjuster mounting bolt using the same method. It is the bolt you indexed earlier. These should be the only two bolts holding the upper control arm in. Some makes, models and year differ from this pattern; remove any additional bolts.
