Solution

1. Preparation

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

2. Tire Inspection

Sub-steps:
1. Remove all four tires using a socket set.
2. Visually inspect each tire for any signs of damage like cracks or bulges.
3. Measure tire tread depth to ensure it is within safe limits.
4. Check for uneven wear patterns that could indicate alignment issues.

3. Wheel Balancing

Sub-steps:
1. Mount each tire onto a wheel balancer.
2. Spin the wheel and check for any imbalance.
3. Add wheel weights as necessary to achieve balance, following the manufacturer's guidelines for weight placement.

4. Suspension Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect all suspension components for any signs of wear or damage.
3. Replace any worn or damaged components, including bushings, shocks, or struts.

5. Wheel Alignment

Sub-steps:
1. Position the vehicle on an alignment rack.
2. Follow the machine’s instructions to measure the alignment angles.
3. Adjust camber, caster, and toe angles to meet the specifications set by the manufacturer.
