Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use a jack to lift the vehicle and secure it with jack stands.

2. Tire Pressure Check

Remove the valve caps from all tires.
Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to the recommended PSI found on the driver’s door jamb.

3. Tire Inspection

Examine each tire for signs of uneven wear: cupping, bald spots, or sidewall bulges.
Replace any damaged or excessively worn tires.

4. Wheel Alignment

Take the vehicle to a certified alignment shop.
Adjust the alignment settings according to manufacturer specifications (caster, camber, toe).

5. Suspension and Brake Inspection

Inspect suspension components for signs of wear or damage, focusing on bushings and ball joints.
Replace any worn components as necessary.
Check brake calipers and pads for even wear; replace if any caliper is sticking or if pads are worn unevenly.
