Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and turn off the engine.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Take off the wheel to gain access to the shock absorber.

3. Remove Shock Absorber

Tools Required: Socket set, ratchet
Locate the upper and lower mounting bolts of the shock absorber.
Use the socket set to remove the upper mounting bolt first.
Then, remove the lower mounting bolt.
Carefully pull the shock absorber out from its mounting location.

4. Install New Shock Absorber

Tools Required: Torque wrench
Position the new shock absorber into place.
Insert the lower mounting bolt and hand-tighten it.
Insert the upper mounting bolt and hand-tighten it.
Use a torque wrench to tighten the upper and lower bolts to the manufacturer's specified torque (typically around 50-60 ft-lbs; verify with a repair manual for exact specs).

5. Reinstall Wheel

Place the wheel back on the hub.
Hand-tighten the lug nuts in a star pattern.
Lower the vehicle and then use the torque wrench to tighten the lug nuts to the manufacturer’s specification (usually 76-80 ft-lbs).
