Solution

1. Preparation

Ensure the vehicle is parked on a level surface and set the parking brake.
Gather tools and equipment: jack, jack stands, socket set, pry bar, torque wrench, and possibly a stethoscope for noise isolation.

2. Raise the Vehicle

Use the jack to lift the vehicle and secure it on jack stands.
Make sure the vehicle is stable before proceeding with any repairs.

3. Remove Components

Sway Bar Links:
- Using the socket set, remove the bolts securing the sway bar links.
- Inspect for wear and replace if necessary.
Struts/Shocks:
- Remove the wheel using the socket set.
- Unbolt the strut assembly from the lower control arm and the top mount.
- Inspect for leaks or damage and replace if needed.

4. Inspect and Replace

Control Arm Bushings:
- Locate the control arms and inspect the bushings for cracks or degradation.
- Remove the old bushings using a press and install new ones according to specifications.
Ball Joints and Tie Rod Ends:
- Use the pry bar to check for excessive play; if play is present, remove and replace.
- Follow manufacturer specifications for torque values when reinstalling.

5. Reassembly

Reattach all removed components, ensuring all bolts are torqued to manufacturer specifications.
Reinstall the wheel and lower the vehicle.
