Solution

1. Preparation

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

2. Lift the Vehicle

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

3. Inspect and Replace Worn Components

Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Disconnect the strut from the lower control arm and upper mounting points.
- Replace with new struts or shocks if they are leaking or excessively worn.
- Torque the upper mounting bolts to the manufacturer's specification.
Bushings:
- Inspect control arm bushings for cracks or deterioration.
- If damaged, press out the old bushings and press in new ones.
- Ensure proper alignment during installation.

4. Reassemble Components

Reattach the strut assembly and tighten all bolts to the specified torque.
Reinstall the wheel and lower the vehicle.

5. Final Checks

Perform a test drive to ensure normal operation and check for noise.
Re-inspect the suspension components for any signs of movement or noise.
