Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, impact wrench.
Ensure the vehicle is parked on a flat surface, and the engine is off. Engage the parking brake.

2. Tire Inspection and Balancing

Sub-steps:
1. Remove the tire and wheel assembly using an impact wrench.
2. Inspect the tire for any bulges, cracks, or uneven wear patterns.
3. Measure tire pressure with a tire pressure gauge; inflate to manufacturer specifications if low.
4. Take the tire to a tire shop or use a wheel balancing machine to balance the tire.
5. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

3. Suspension Component Check

Sub-steps:
1. Visually inspect the suspension components (shocks, struts, control arms) for any signs of wear, leaks, or damage.
2. If necessary, replace any worn or damaged components. Use OEM or equivalent parts.
3. Ensure all bolts are tightened to the specified torque values.

4. Wheel Bearing and Driveshaft Inspection

Sub-steps:
1. Jack up the vehicle and support it securely using jack stands.
2. Grab the wheel at the 12 and 6 o'clock positions and wiggle it. Any play indicates a bad wheel bearing.
3. If wheel bearings are bad, remove the wheel hub and replace the bearings.
4. Inspect the driveshaft for any visible damage or excessive play at CV joints. Replace any damaged components.

5. Alignment Adjustment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Request a four-wheel alignment to ensure all angles are within manufacturer specifications.
3. Confirm that the alignment settings are adjusted as needed.
