Solution

1. Preparation

Gather tools and parts: socket set, torque wrench, jack stands, and replacement shocks or springs if necessary.
Park the vehicle on a level surface and ensure the engine is off.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Replace Shock Absorbers

Lift the Vehicle:
- Use a jack to raise the vehicle and secure it with jack stands.
Remove the Wheel:
- Use a socket set to remove the lug nuts and take off the wheel for better access.
Remove Old Shocks:
- Locate the upper and lower bolts securing the shock absorber.
- Remove the bolts using a socket wrench and carefully detach the shock from the mounting points.
Install New Shock Absorbers:
- Position the new shock absorber in place.
- Hand-tighten the bolts, then use a torque wrench to secure them to the manufacturer's specifications (typically around 30-50 ft-lbs).

3. Inspect and Replace Coil Springs (if necessary)

Remove the Lower Control Arm:
- Remove the bolts connecting the lower control arm to facilitate spring removal.
Remove the Old Spring:
- Use a spring compressor to safely compress the coil spring.
- Detach the top and bottom mounts, and carefully remove the spring.
Install New Coil Spring:
- Place the new spring in position, ensuring it is seated correctly in the spring perch.
- Release the spring compressor slowly, allowing the spring to settle.
Reassemble:
- Reconnect the lower control arm and torque bolts to specifications.
- Reinstall the wheel and lower the vehicle.
