Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Gather safety equipment such as gloves and safety glasses.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to match the manufacturer's recommended PSI found on the driver’s door jamb label.

3. Tire Inspection and Rotation

Remove all four wheels using a lug wrench.
Inspect each tire for uneven tread wear, indicating misalignment or issues with suspension components.
Rotate the tires if uneven wear is found, following the manufacturer's recommended rotation pattern.

4. Wheel Alignment

If misalignment is suspected, take the vehicle to a certified alignment shop.
The technician will use alignment equipment to adjust camber, caster, and toe settings to the manufacturer's specifications.

5. Suspension Component Inspection and Replacement

Visually inspect all suspension components for wear (bushings, struts, shocks).
Replace any worn components with new OEM or quality aftermarket parts.
Reassemble and torque all bolts to the manufacturer's specifications.

6. Steering System Check

Inspect the tie rods and steering rack for wear or play.
Replace any damaged components and ensure proper torque is applied to all connections.
