Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Replace Shock Absorbers

Raise the Vehicle:
- Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the Wheel:
- Use a socket set to remove the lug nuts and take off the wheel to access the suspension components.
Detach Shock Absorber:
- Remove the bolts securing the top and bottom of the shock absorber using a socket wrench.
- Carefully extract the shock absorber from the mounting points.
Install New Shock Absorbers:
- Position the new shock absorber in place and secure it with the bolts. Torque the upper and lower bolts to the manufacturer’s specifications (typically around 25-30 Nm, but verify for the specific part).
Reinstall the Wheel:
- Place the wheel back on and hand-tighten the lug nuts. Lower the vehicle and then torque the lug nuts to the specified value (usually around 100 Nm).

3. Check and Replace Other Suspension Components

Inspect Control Arms and Bushings:
- Visually inspect for cracks or excessive wear; replace if necessary.
Replace Stabilizer Links:
- Disconnect the stabilizer link from the control arm and sway bar using a wrench. Replace with new links and secure them according to specifications.
