Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and eyewear.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the area you're inspecting.
Secure the vehicle on jack stands for safety.

3. Inspect and Replace Shock Absorbers

Inspect: Check for any oil leaks around the shock absorbers.
Remove:
- Use a socket set to remove the bolts securing the shock absorber to the vehicle.
- Disconnect any associated components, such as sway bar links if applicable.
Install New Shock Absorbers:
- Position the new shock absorber in place.
- Torque the mounting bolts to manufacturer specifications (typically between 25-35 ft-lbs, but refer to the service manual for exact values).

4. Inspect and Replace Springs (if necessary)

Inspect: Look for any broken or sagging coils.
Remove:
- Unbolt the lower control arm or spring seat to relieve tension.
- Carefully remove the old spring.
Install New Springs:
- Position the new spring in place.
- Reattach the control arm or spring seat and torque to specifications.

5. Reassemble Components

Reattach any components that were removed for access.
Lower the vehicle from the jack stands.
