Solution

1. Preparation

Gather tools and parts before starting the repair.
Park the vehicle on a level surface and ensure it is in "Park" (automatic) or in gear (manual).
Use wheel chocks to prevent the vehicle from rolling.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench, pry bar.
Inspect control arms, sway bar links, and strut mounts for damage.
Using a socket set, tighten all suspension bolts to the manufacturer's specified torque values.
Replace any worn or damaged bushings or mounts as necessary.

3. Replace Worn Suspension Components

Tools Required: Jack and jack stands, socket set, torque wrench.
If any components are found to be worn (e.g., struts, shocks, bushings):
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access the suspension components.
- Follow the service manual for specific removal procedures of struts or shocks.
- Install new components, ensuring to torque bolts to specified values.

4. Reassemble and Test
