Solution

1. Preparation

Gather necessary tools and parts, ensuring the vehicle is on a flat, level surface.
Tools Required: Jack and jack stands, tire pressure gauge, lug wrench, wheel balancer.

2. Tire Inspection and Replacement

Inspect Tires:
- Check each tire for uneven wear patterns, bulges, or punctures.
- Use a tire pressure gauge to ensure proper inflation.
Replace Tires (if needed):
- Remove the damaged tire using a lug wrench.
- Install a new tire, ensuring it is properly seated on the rim.
- Torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Wheel Balancing

Mount the wheel on the wheel balancer.
Follow the manufacturer's instructions to balance the tire, adding weights as necessary.
Repeat for all four wheels to ensure proper balance.

4. Suspension and Alignment Check

Inspect suspension components for damage:
- Check control arms, bushings, and shock absorbers for signs of wear.
Adjust Alignment:
- If misalignment is found, adjust using an alignment machine according to manufacturer specifications.

5. Driveshaft and CV Joint Inspection

Inspect the driveshaft and CV joints for any leaks or damage.
If damaged, replace the affected components:
- Remove the driveshaft and/or CV joint using appropriate tools.
- Install new components, ensuring all fasteners are tightened to specifications.
