Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and engage the parking brake.
Required tools: Jack, jack stands, torque wrench, tire pressure gauge, wheel balancer, alignment machine.

2. Tire Pressure Adjustment

Use the tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to match the manufacturer's recommended specifications found on the door jamb sticker.

3. Wheel Balancing

Remove the wheel from the vehicle using the jack and jack stands.
Mount the wheel on the dynamic wheel balancer.
Adjust weights on the rim as indicated by the balancer to correct any imbalance.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specification (usually around 100 Nm).

4. Suspension Inspection

Visually inspect tie rods, ball joints, and control arms for signs of wear or damage.
Replace any worn or damaged components as necessary.
If components are replaced, ensure all hardware is torqued to specification.

5. Wheel Alignment

Set up the vehicle on an alignment machine.
Adjust the camber, caster, and toe settings to manufacturer specifications.
Confirm all settings are within the recommended range and lock adjustments.
