Solution

1. Preparation

Gather necessary tools and ensure a safe working environment.
Park the vehicle on a level surface and engage the parking brake.

2. Tire Inspection and Inflation

Use a tire pressure gauge to check the air pressure in all tires.
Inflate tires to the recommended PSI as indicated in the owner’s manual.
Visually inspect tires for any signs of bulges, cracks, or uneven wear.

3. Wheel Balancing

Remove the wheels from the vehicle using a socket set.
Take the wheels to a tire shop for balancing.
Reinstall the wheels on the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

4. Wheel Alignment

Use a professional alignment machine to check the wheel alignment.
Adjust the alignment settings to the manufacturer specifications as required.

5. Suspension Component Inspection

Visually inspect the suspension components for any visible wear, such as cracked bushings or leaking struts.
If any components are damaged, replace them with OEM parts.
Reassemble any disassembled parts and ensure everything is tightened to the correct torque specifications.
