Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety: Use wheel chocks and jack stands to secure the vehicle.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure the vehicle with jack stands.

3. Inspect and Replace Worn Components

Shock Absorbers:
- Remove the wheel.
- Unbolt the top and bottom mount of the shock absorber using the appropriate socket.
- Replace with new shock absorbers, ensuring they are properly torqued to manufacturer specifications (typically around 30-45 Nm).
Sway Bar Links:
- Locate the sway bar links and inspect for wear.
- Remove the bolts securing the sway bar link using a socket wrench.
- Replace with new sway bar links, tightening to manufacturer specifications (typically around 25-30 Nm).
Bushings:
- Inspect control arm bushings and sway bar bushings for cracks or deterioration.
- If damaged, use a bushing press to remove the old bushings and install new ones, ensuring they are properly seated.

4. Reassemble and Lower the Vehicle

Reattach the wheel and torque the lug nuts to the specified torque (usually around 100 Nm).
Carefully lower the vehicle to the ground.
