Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, tire pressure gauge, wheel balancer, alignment equipment.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake for safety.

2. Tire Inspection

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer's recommended PSI.
Examine Tire Condition: Look for any signs of bulges, cracks, or uneven wear patterns.
Rotate Tires: If uneven wear is detected, consider rotating the tires to promote even wear.

3. Wheel Balancing

Remove Wheels: Use a lug wrench to loosen and remove the wheel nuts and take the wheels off the vehicle.
Balance Wheels: Mount each wheel on a wheel balancer to check for imbalances. Adjust weights as necessary to achieve balance.
Reinstall Wheels: Place the balanced wheels back onto the vehicle and torque the lug nuts to the manufacturer’s specifications.

4. Suspension Inspection

Visual Inspection: Examine all visible suspension components for signs of wear, such as cracked bushings or bent control arms.
Test for Play: With the vehicle raised, use your hands to check for play in the ball joints and tie rods.

5. Alignment Check

Perform Alignment: Use alignment equipment to check the alignment settings. Adjust as necessary to meet manufacturer specifications.

6. Driveshaft and CV Joint Inspection (if applicable)

Inspect Driveshaft: Look for any signs of wear, including cracks or excessive play in the universal joints.
Check CV Joints: Inspect for torn boots or excessive play in the CV joints. Replace if necessary.
