Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Replace Shock Absorbers

Remove the Wheel:
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove lug nuts with a socket wrench and take off the wheel.
Remove Old Shock Absorbers:
- Locate the upper and lower mounting bolts of the shock absorber.
- Use a socket set to remove the bolts and detach the shock absorber from the vehicle.
- Carefully pull the shock absorber out of its mount.
Install New Shock Absorbers:
- Insert the new shock absorber into the mounting position.
- Reattach the upper and lower bolts; tighten to manufacturer specifications (usually found in the service manual, typically 30-40 Nm).
Reinstall the Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and tighten the lug nuts to the specified torque (usually around 100 Nm).

3. Check Alignment

Alignment Adjustment:
- After replacing the shocks, take the vehicle to a professional alignment shop.
- Ensure all suspension angles are adjusted to manufacturer specifications.
