Solution

1. Preparation

Gather Tools: Socket set, jack and jack stands, torque wrench, pry bar, and a multimeter.
Safety Warning: Ensure the vehicle is on a flat surface and securely supported on jack stands before starting the repair.

2. Remove Shock Absorbers

Lift the Vehicle: Use a jack to raise the vehicle and support it with jack stands.
Remove Wheel: Take off the wheel where the shock absorber is being replaced.
Unbolt Shock Absorber: Remove the bolts securing the shock absorber at both the top and bottom mounting points using a socket wrench.
Extract Shock Absorber: Gently pull the shock absorber out of the mounting location.

3. Inspect and Replace Components

Inspect Shock Absorber: Check for leaks or signs of damage. If defective, proceed to replace it.
Install New Shock Absorber: Position the new shock absorber in place, ensuring it is aligned with mounting points.
Secure Bolts: Tighten the top and bottom bolts to the manufacturer's specified torque (usually around 30-50 Nm, check the service manual for exact specs).

4. Reassemble

Reattach Wheel: Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower Vehicle: Carefully lower the vehicle back to ground level.
Torque Wheel Nuts: Once on the ground, use a torque wrench to tighten the lug nuts to the specified torque (typically 120 Nm).
