Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, wheel balancer, alignment tools.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Tire Inspection and Balancing

Lift the Vehicle: Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove Front Wheels: Loosen the lug nuts and remove the front wheels.
Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer's recommended levels.
Inspect Tires: Look for uneven wear, bulges, or damage. Replace tires if necessary.
Balance Tires: Place the tires on a wheel balancer and adjust weights as needed to ensure proper balance.

3. Suspension Inspection

Visual Inspection: Check for worn or damaged bushings, ball joints, and tie rod ends.
Shake Test: With wheels off the ground, grasp each wheel at the top and bottom and shake. Any noticeable movement indicates worn components that may need replacement.

4. Wheel Alignment

Set Up Alignment Equipment: Position the alignment tool according to the manufacturer’s instructions.
Adjust Alignment: Follow the tool's guidance to adjust camber, caster, and toe settings to the manufacturer's specifications.

5. Reassembly

Reinstall Wheels: Place the front wheels back onto the hubs and hand-tighten lug nuts.
Lower Vehicle: Carefully remove jack stands and lower the vehicle back to the ground.
Torque Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque value.
