Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands to ensure safety during inspection.

3. Inspect Suspension Components

Check Shock Absorbers:
- Look for signs of fluid leakage.
- Compress and release each shock absorber to assess damping.
Inspect Control Arms:
- Check bushings for cracking or excessive wear.
- Ensure bolts are torqued to manufacturer specifications.
Examine Sway Bar Links:
- Verify that sway bar links are not bent or damaged.
- Replace any worn bushings.

4. Replace Worn Components

If Shock Absorbers are Faulty:
- Remove the wheel to access shock mounts.
- Unscrew the top mount and lower mount bolts.
- Replace with new shocks, following torque specifications.
If Control Arm Bushings are Worn:
- Remove the control arm from the vehicle.
- Press out old bushings and install new ones.
- Reinstall the control arm and torque to specifications.

5. Reassemble and Lower Vehicle

Reattach the wheel and lower the vehicle from jack stands.
Ensure all tools are removed from under the vehicle.
