Control Arm Bushings:
- If worn, remove the control arm bolts and detach the control arm.
- Replace the bushings with new ones and reassemble the control arm using torque specifications from the manufacturer.
Strut Assembly:
- If struts are damaged, remove the strut assembly by unbolting it from the top mount and lower control arm.
- Replace with new struts and ensure they are torqued according to manufacturer’s specifications.
Sway Bar Links:
- Check the sway bar links for wear; replace if necessary by removing the bolts on both ends and installing new links.

4. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
