Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, socket set, suspension testing tool (if needed)
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electronic suspension components.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers or lug nut caps (if applicable).
2. Loosen the lug nuts slightly but do not remove.
3. Jack up the vehicle and secure it on jack stands.
4. Remove the lug nuts and take off the wheels.
5. Inspect the tires for uneven wear, bulges, or damage; replace if necessary.
6. Check and adjust tire pressure according to manufacturer specifications.

3. Suspension Component Inspection

Sub-steps:
1. Visually inspect the shocks and struts for leaks or physical damage.
2. Push down on the corners of the vehicle. It should bounce once and return to rest. If it continues to bounce, replace the shocks/struts.
3. Check for broken or sagging springs; replace if necessary.

4. Alignment and Balancing

Sub-steps:
1. Use a professional alignment tool to check the alignment settings.
2. Adjust the alignment according to manufacturer specifications.
3. Balance the wheels if there are vibrations felt at higher speeds.

5. Reassembly

Reinstall wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Reconnect the battery if it was disconnected.
