Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to prevent any electrical issues during repairs.

2. Inspect and Replace Worn Components

Remove Wheels:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the wheels.
Inspect Struts and Shocks:
- Check for leaks, dents, or physical damage.
- If damaged, proceed to replace the struts or shocks.
Replace Struts/Shocks:
- Remove the bolts securing the strut/shock to the lower control arm and upper mount.
- Install the new strut/shock in reverse order, tightening to manufacturer specifications (usually around 50-60 ft-lbs).
Inspect and Replace Bushings:
- Use a pry bar to check for play in the bushings.
- If worn, remove the old bushings and press in new ones using a bushing tool or a suitable press.

3. Reassemble and Torque

Reinstall Wheels:
- Place the wheels back on and hand-tighten the lug nuts.
Lower Vehicle:
- Carefully lower the vehicle back to the ground.
Torque Lug Nuts:
- Using a torque wrench, tighten the lug nuts to the manufacturer's specifications (usually around 100 ft-lbs).
