Solution

1. Preparation

Gather tools and parts necessary for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Allow the suspension to settle by rolling the vehicle back and forth.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels for better access to suspension components.

3. Inspect and Replace Worn Components

Shocks and Struts:
- Remove the bolts securing the shock absorbers.
- Inspect for leaks or damage; replace if necessary.
- Use a torque wrench to tighten to manufacturer specifications when installing new shocks.
Bushings:
- Remove any components obstructing access to bushings.
- Use a bushing tool to remove worn bushings.
- Install new bushings and lubricate them as needed.
Control Arms:
- Check for any cracks or bends in control arms.
- Replace if damaged, ensuring proper alignment during installation.

4. Reassembly

Reattach any components that were removed.
Ensure all nuts and bolts are tightened to the specified torque values.

5. Lower the Vehicle

Carefully lower the vehicle back to the ground.
Reinstall the wheels and tighten lug nuts to the specified torque.
