Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Jack, jack stands, socket set, pry bar, torque wrench, and a flashlight.

2. Lift the Vehicle

Use a jack to lift the vehicle from the designated jacking points.
Secure the vehicle on jack stands to ensure safety.

3. Inspect and Replace Suspension Components

Check Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Inspect for oil leakage and signs of wear on the strut/shock.
- If damaged, remove the strut/shock by unbolting it from the top and bottom, and replace with new units.
- Torque the bolts to manufacturer specifications.
Inspect Sway Bar Links:
- Check the sway bar links for any signs of damage or wear.
- If damaged, remove the sway bar link bolts and replace with new ones. Torque to specifications.

4. Tighten Loose Bolts

Go through all suspension components and tighten any loose bolts found during inspection.
Use a torque wrench to ensure all bolts are tightened to the manufacturer’s specified torque values.

5. Reassemble and Lower Vehicle

Reattach the wheel and lower the vehicle back to the ground.
Ensure all tools are removed from the work area and check that everything is secure.
