Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the shock absorbers.

2. Remove Shock Absorbers

Sub-step 1: Remove the bolts securing the bottom of the shock absorber to the axle or suspension arm using a socket set.
Sub-step 2: Remove the top mounting bolts of the shock absorber using a ratchet and socket.
Sub-step 3: Carefully pull out the shock absorber from its mount.

3. Inspect and Replace

Sub-step 1: Compare the old shock absorber with the new one to ensure proper fit.
Sub-step 2: Install the new shock absorber by inserting it into the mount and securing it with the top bolts first.
Sub-step 3: Reattach the bottom of the shock absorber to the axle or suspension arm and tighten the bolts to the manufacturer's torque specifications (typically around 30-40 ft-lbs).

4. Reassemble and Lower Vehicle

Sub-step 1: Reinstall the wheels and hand-tighten the lug nuts.
Sub-step 2: Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
Sub-step 3: Perform a final inspection to ensure all components are secure.
