Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat, stable surface and engage the parking brake.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Components

Inspect Struts/Shocks:
- Remove the wheels using a socket set.
- Check for fluid leaks, dents, or damage on the struts/shocks.
- If damaged, remove the strut/shock by loosening the mounting bolts (consult torque specifications).
- Replace with new strut/shock and torque bolts to manufacturer specifications.
Check Sway Bar Links:
- Inspect sway bar links for wear or separation.
- Remove and replace links if any play is detected.
- Tighten to manufacturer specifications.
Inspect Bushings and Ball Joints:
- Check for cracks or degradation in bushings.
- Use a pry bar to check for play in ball joints; if worn, replace them.
- Remove and install new bushings/ball joints, ensuring proper alignment.

4. Reassemble and Lower the Vehicle

Reattach the wheels and tighten the lug nuts to the specified torque.
Carefully lower the vehicle from the jack stands.
