Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use jack stands to secure the vehicle after jacking it up.

2. Inspect and Replace Suspension Components

Remove Wheels
- Use a lug wrench to loosen the lug nuts.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheels for better access to suspension components.
Inspect Struts and Shocks
- Check for any oil leakage on struts and shocks.
- Push down on the suspension to observe if it bounces excessively, indicating worn shocks.
- If found defective, proceed to replace them.
Replace Worn Bushings
- Inspect control arm and sway bar bushings for cracks or wear.
- If damaged, remove the bolts securing the control arms and sway bar.
- Replace the old bushings with new ones, ensuring they are installed in the correct orientation.
Reassemble Components
- Reattach the struts, shocks, and any other components that were removed.
- Ensure all nuts and bolts are torqued to manufacturer specifications.
Reinstall Wheels
- Place the wheels back onto the hubs and hand-tighten the lug nuts.
- Lower the vehicle and use a torque wrench to tighten the lug nuts to the specified torque rating.
