Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate the tires to match the recommended tire pressure listed in the owner’s manual.
Recheck the pressure after adjustment to ensure accuracy.

3. Tire Inspection and Replacement

Examine each tire for signs of uneven wear, bulges, or punctures.
If any tires are deemed unserviceable, replace them with the correct size and type.
Ensure all tires are balanced during installation.

4. Wheel Alignment

Using a wheel alignment machine, set the vehicle to the manufacturer's alignment specifications.
Adjust camber, caster, and toe angles as necessary.
Tighten all bolts to the specified torque values after making adjustments.

5. Suspension Component Inspection

Visually inspect suspension components for wear, such as bushings, control arms, and struts.
Replace any worn or damaged parts with OEM or high-quality aftermarket replacements.
Ensure all mounting bolts are tightened to the manufacturer’s specifications.
