Solution

1. Preparation

Gather tools and parts necessary for the repair.
Park the vehicle on a level surface and engage the parking brake.
Ensure safety gear is worn (gloves, safety glasses).

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate the tires to match the manufacturer’s recommended specifications.

3. Tire Inspection and Replacement

Remove each wheel using a lug wrench.
Inspect tires for uneven wear, bulges, or foreign objects.
If damaged, replace tires with new ones that meet OEM specifications.
Reinstall the wheels and tighten lug nuts to the specified torque (typically 80-100 ft-lbs).

4. Wheel Balancing

Mount the tires on a wheel balancing machine.
Adjust weights as needed to achieve balance.
Reinstall balanced tires on the vehicle.

5. Suspension Component Inspection

Visually inspect suspension components for cracks or excessive wear.
Replace any worn parts (e.g., control arms, bushings) as necessary.
Ensure components are torqued to manufacturer specifications.

6. Wheel Alignment

Perform a four-wheel alignment using an alignment machine.
Adjust camber, caster, and toe settings to meet manufacturer specifications.
