Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and ensure it is in gear or "Park".
Use wheel chocks to prevent movement.

2. Inspect and Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, jack stands, wheel chocks, pry bar
Sub-steps:
1. Lift the front or rear of the vehicle using a jack and secure with jack stands.
2. Remove the wheels to access suspension components.
3. Inspect control arms, bushings, ball joints, and struts for signs of damage or wear.
4. If any components are found to be worn (e.g., torn bushings, leaking struts), remove the damaged part using the socket set.
5. Install new components, ensuring they are torqued to the manufacturer's specifications.

3. Check and Tighten Loose Bolts

Sub-steps:
1. Examine all suspension mounting points for loose bolts.
2. Tighten any loose bolts to the specified torque values.

4. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheels and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground and then torque the lug nuts to the manufacturer's specifications.
