Solution

1. Preparation

Tools Required: Tire pressure gauge, jack and jack stands, alignment machine.
Park the vehicle on a level surface and turn off the engine.
Ensure the vehicle is cool before starting any work.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the tire pressure on all four tires.
Inflate or deflate tires as necessary to meet the recommended pressure specified in the owner’s manual.

3. Check and Rotate Tires

Inspect the front tires for uneven wear patterns.
If uneven wear is found, rotate the tires to promote even wear across all tires.
Recheck the alignment after rotating the tires.

4. Suspension Inspection

Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the control arms, bushings, and ball joints for any signs of wear or damage.
Replace any worn or damaged components with OEM or high-quality aftermarket parts.

5. Wheel Alignment Adjustment

If the alignment check indicates misalignment, use an alignment machine to adjust the camber, caster, and toe settings according to the manufacturer’s specifications.
Tighten all bolts to the manufacturer's torque specifications.
