Socket set
Torque wrench
Pry bar
Jack and jack stands
Inspection mirror

2. Inspect and Replace Worn Suspension Components

Remove the Wheel:
- Loosen lug nuts using a socket.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the wheel.
Inspect the Struts and Shocks:
- Check for oil leakage on struts and shocks.
- If damaged, remove the strut assembly by unbolting it from the top mount and the lower control arm.
Replace Worn Parts:
- If the strut/shock is worn, install a new one:
  - Position the new shock/strut in place.
  - Secure it to the strut tower and lower control arm with bolts.
  - Torque bolts to manufacturer specifications (typically 15-20 ft-lbs).
Check Sway Bar Links:
- Inspect for wear or damage.
- If damaged, remove the sway bar link using a socket.
- Install the new sway bar link and torque to manufacturer specifications.
Reassemble:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle, then torque the lug nuts to specification (usually 80-100 ft-lbs).
