Solution

1. Preparation

Gather tools: tire pressure gauge, jack, jack stands, socket set, torque wrench, alignment tools (if available).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure in each tire.
Inflate tires to the manufacturer's specified pressure (found on the driver's door jamb).
Recheck pressure after adjustments.

3. Alignment Adjustment

If misalignment is detected, take the vehicle to a professional alignment shop.
Ensure alignment is set according to manufacturer specifications.
Adjust camber, caster, and toe angles as necessary.

4. Suspension Inspection and Repair

Inspect suspension components for wear, such as bushings, struts, and control arms.
Replace any worn components with OEM or high-quality aftermarket parts.
Reassemble and torque bolts to manufacturer specifications (refer to service manual for torque values).

5. Tire Rotation and Replacement

Rotate tires to ensure even wear (follow the recommended rotation pattern).
If tires are excessively worn, replace with new tires of the same size and type.
Balance new tires to prevent future uneven wear.
