Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Wrench set
- Torque wrench
- Spring compressor (if replacing front shocks)
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported by jack stands before starting work.

2. Remove the Shock Absorber

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel corresponding to the shock absorber being replaced.
Locate the shock absorber mounting bolts (top and bottom).
Use a socket set to remove the lower mounting bolt first, then the upper mounting bolt. Keep these bolts for reinstallation.
Carefully pull out the shock absorber from its mount.

3. Inspect and Replace

Inspect the old shock absorber for damage and confirm it is leaking.
If the shock is damaged, replace it with a new shock absorber.
Position the new shock absorber and insert it into the mounting location.
Secure the upper mount first, followed by the lower mount. Torque to manufacturer specifications (typically around 50-60 ft-lbs for lower mounts and 25-35 ft-lbs for upper mounts).

4. Reassemble and Test

Reinstall the wheel and tighten the lug nuts to the specified torque (usually around 100-110 ft-lbs).
Lower the vehicle back to the ground.
Perform a bounce test to ensure proper installation and function of the new shock absorber.
