Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed, securing it with jack stands.
Ensure the vehicle is stable before working underneath.

3. Inspect and Replace Worn Components

Control Arms/Ball Joints
- Remove the wheel to access suspension components.
- Use a socket set to unbolt the control arm or ball joint.
- Inspect for wear and replace if necessary, using grease as specified.
Sway Bar Links
- Locate the sway bar links.
- Use a wrench to remove the nuts from both ends of the sway bar link.
- Replace with new sway bar links and secure them with the manufacturer-specified torque.
Shock Absorbers/Struts
- Detach the top mount of the shock absorber or strut.
- Remove the lower mounting bolts using a socket set.
- Replace the shock absorber or strut with a new unit, ensuring proper alignment with mounting points.

4. Reassembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer’s specifications.
