Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Lift the Vehicle

Use a hydraulic jack to raise the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Components

Struts:
- Remove the wheel and brake components.
- Disconnect the strut from the lower control arm and top mount.
- Inspect the strut for leaks or damage.
- If damaged, replace with new struts, ensuring proper torque specifications are followed during installation.
Control Arms:
- Remove the control arm by loosening the bolts connecting it to the frame and wheel hub.
- Inspect bushings for cracks or separation; replace if necessary.
- Install new control arms, tightening bolts to manufacturer specifications.
Sway Bar Links:
- Check sway bar links for wear; replace if loose or damaged.
- Disconnect old links and install new ones with proper torque.

4. Reassemble and Lower Vehicle

Reattach the wheel and any removed brake components.
Lower the vehicle from jack stands and remove the hydraulic jack.

5. Final Inspection

Conduct a visual inspection of all components and ensure that all bolts are tightened to specification.
