Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Tire Inspection and Replacement

Visual Inspection
- Check each tire for visible damage, bulges, or uneven wear patterns.
- Tools required: None
Pressure Check
- Use a tire pressure gauge to ensure tires are inflated to the manufacturer’s specifications.
- Tools required: Tire pressure gauge
Replacement
- If tires are damaged or excessively worn, replace them with new tires of the same size and specifications.
- Torque the wheel lug nuts to the manufacturer's recommended torque settings (typically 80-100 ft-lbs).

3. Wheel Balancing

Remove Tires
- Use a jack to lift the vehicle and remove the wheel and tire assembly.
- Tools required: Jack, jack stands, lug wrench
Balance Check
- Mount the wheel on a wheel balancer and check for imbalance.
Adjust Balancing Weights
- Add or remove weights as necessary to achieve proper balance.
- Tools required: Wheel balancer, adhesive weights

4. Suspension and Alignment Check

Inspect Suspension Components
- Check control arms, tie rods, and bushings for wear or damage.
- Tools required: Visual inspection, pry bar for testing
Perform Wheel Alignment
- Adjust the alignment settings using an alignment machine according to manufacturer specifications.
- Tools required: Alignment machine

5. Brake Inspection

Check Brake Rotors
- Inspect rotors for warping or damage; measure thickness with a micrometer.
- Tools required: Micrometer
Replace Rotors if Necessary
- Remove wheels and calipers, replace rotors, and reinstall.
- Torque caliper bolts and wheel lug nuts to specifications.
