Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts with a lug wrench and take off the wheel.

3. Inspect and Replace Shock Absorbers

Inspection:
- Check for fluid leaks or physical damage on the shock absorber.
- If damaged, proceed to replacement.
Replacement:
- Unbolt the top mount of the shock absorber using a socket set.
- Remove the lower mounting bolt connecting the shock to the control arm.
- Install the new shock absorber by reversing the removal steps.
- Torque the top mount bolts to manufacturer specifications (usually around 20-25 Nm).
- Torque the lower mounting bolt to manufacturer specifications (around 50 Nm).

4. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification (usually around 120 Nm).
Test drive the vehicle to assess handling and suspension performance.
