Solution

1. Preparation

Gather tools and parts required.
Safely park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the wheels of the respective shock absorbers without removing them.

2. Raise the Vehicle

Use a jack to raise the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheels to access the shock absorbers.

3. Remove Old Shocks

Locate the upper and lower mounting bolts of the shock absorbers.
Use a socket wrench to remove the upper mounting bolt(s) first.
Then, remove the lower mounting bolt(s) to detach the shock from the vehicle.
Carefully remove the shock absorber from its mounting location.

4. Install New Shocks

Position the new shock absorber in place, ensuring it aligns with the mounting points.
Begin by installing the lower mounting bolt and tightening it to the manufacturer’s torque specifications.
Next, install the upper mounting bolt and tighten it as well.

5. Reassemble

Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle to the ground and then torque the lug nuts to the correct specifications.
Repeat the process for the other side if replacing both shock absorbers.

6. Final Inspection

Check all mounting bolts to ensure they are properly torqued.
Inspect the shock absorbers for proper installation.
