Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Pry bar
- Inspection mirror
Ensure the vehicle is parked on a level surface and the engine is off.

2. Component Inspection

Raise the vehicle using a jack and secure it with jack stands.
Use the inspection mirror to check hard-to-see areas of the suspension.
Inspect struts, control arms, and sway bar links for any visible damage.

3. Replace Worn Parts

Control Arm Bushings:
- Remove the bolts securing the control arm.
- Use a pry bar to remove the old bushings and install new ones.
- Reinstall the control arm and torque the bolts to manufacturer specifications (typically around 85 ft-lbs).
Struts:
- Remove the wheel for access to strut bolts.
- Unbolt the strut from the top mount and lower control arm.
- Replace with a new strut and torque bolts to specifications (generally around 40 ft-lbs for top mount and 70 ft-lbs for lower).
Sway Bar Links:
- Remove the nuts securing the sway bar link.
- Replace with a new link and torque to specifications (typically around 35 ft-lbs).

4. Reassemble

Reinstall all removed components securely and check all fasteners.
Lower the vehicle back to the ground.
