Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on suspension components.

2. Tire Inspection

Tools Required: Tire pressure gauge, jack, jack stands.
Check each tire’s pressure and inflate to the recommended PSI if necessary.
Inspect each tire for bulges, cuts, or uneven wear patterns.
Replace any damaged tires if needed.

3. Wheel Balancing

Tools Required: Wheel balancer, torque wrench.
Remove the wheels from the vehicle using the jack and jack stands.
Mount each wheel on the balancer and adjust weights as necessary to achieve balance.
Reinstall the wheels, ensuring proper torque specifications (typically 100-120 ft-lbs).

4. Wheel Alignment

Tools Required: Alignment machine, alignment shims if necessary.
Using an alignment machine, check the alignment specifications against manufacturer standards.
Adjust the alignment as needed to correct camber, caster, and toe angles.

5. Suspension Inspection

Tools Required: Wrench set, pry bar.
Visually inspect all suspension components for wear, cracks, or looseness.
Replace any worn components, such as control arms or bushings, as needed.
