- Install new shock absorbers, tightening bolts to the manufacturer's torque specifications.
Examine Sway Bar Links:
- Remove the sway bar link bolts with a wrench if loose or worn.
- Replace with new sway bar links and tighten to specification.
Inspect Strut Mounts:
- Remove the strut assembly by unbolting it from the top mount and lower control arm.
- Inspect the strut mount and bearing for wear; replace if necessary.
