Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if electrical components will be handled.

2. Inspect and Replace Worn Suspension Components

Step 1: Lift the Vehicle
- Use a jack to lift the vehicle and secure it with jack stands.
Step 2: Remove the Wheel
- Use a socket set to remove the wheel lug nuts and take off the wheel.
Step 3: Inspect the Struts/Shocks
- Check for any visible leaks or damage on the struts or shocks. If damaged, proceed to replace:
  - Remove the top mounting bolts and bottom bolts using a socket set.
  - Remove the strut/shock from its mount.
  - Install the new strut/shock by reversing the removal process, ensuring to torque the bolts to the manufacturer's specifications (typically around 50-60 ft-lbs).
Step 4: Inspect Sway Bar Links and Bushings
- Check the sway bar links for any looseness or wear. If defective, replace the links:
  - Remove the retaining nuts with a socket set.
  - Replace with new sway bar links, ensuring they are tightened to the manufacturer's torque specifications (usually around 30-40 ft-lbs).

3. Reassemble and Test

Step 1: Reinstall Wheel
- Place the wheel back on and hand-tighten the lug nuts.
Step 2: Lower the Vehicle
- Carefully lower the vehicle back to the ground and fully tighten the lug nuts in a star pattern to the recommended torque (usually around 80-100 ft-lbs).
