Solution

1. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to measure the pressure in each tire.
2. Inflate or deflate tires to match the recommended PSI found in the owner’s manual or on the door jamb sticker.

2. Tire Inspection and Balancing

Sub-steps:
1. Remove the wheel covers, if applicable, and inspect tires for bulges or punctures.
2. If uneven wear is noted, rotate the tires as necessary.
3. Take the vehicle to a tire shop to have tires balanced if imbalance is suspected.

3. Wheel Lug Nut Torque

Sub-steps:
1. Use a torque wrench to check the lug nut torque settings.
2. Tighten the lug nuts to the manufacturer’s specified torque value.

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Follow their instructions for performing a four-wheel alignment.

5. Suspension Inspection

Sub-steps:
1. Raise the vehicle using a hydraulic lift or jack stands.
2. Inspect suspension components for any signs of wear or damage, focusing on bushings and shocks.
3. Replace any worn or damaged components as necessary.

Tools Required:

Tire pressure gauge
Torque wrench
Jack and jack stands
Wheel alignment machine (for professional use)

Parts Required:
