Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools and parts.
Disconnect the battery to prevent any electrical issues during the repair.

2. Raise the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure it with jack stands to ensure safety while working underneath.

3. Inspect and Replace Components

Inspect the Shock Absorbers:
- Remove the wheel to access the shock absorbers.
- Check for oil leakage or physical damage.
- If damaged, remove the shock absorber by unbolting it from the top and bottom mount.
- Replace with a new shock absorber and torque to manufacturer specifications (usually around 40-50 ft-lbs).
Check Control Arms and Bushings:
- Inspect control arms for cracks.
- Remove control arm bolts and replace any worn bushings.
- Reinstall control arms and ensure bolts are torqued properly.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to manufacturer specifications (typically 100-120 ft-lbs).

5. Final Inspection

Double-check all components are secure and recheck the torque on critical suspension bolts.
Reconnect the battery.
