Solution

1. Preparation

Gather tools: jack and jack stands, tire iron, OBD-II scanner, torque wrench, and basic hand tools.
Park the vehicle on a level surface and engage the parking brake.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers or hubcaps (if applicable).
2. Loosen the lug nuts with a tire iron but do not remove them completely.
3. Jack up the vehicle and secure it with jack stands.
4. Remove the lug nuts and take off the wheel.
5. Inspect the tire for bulges, cracks, or uneven wear; replace if necessary.
6. Check tire pressure and inflate to the manufacturer’s recommended PSI.

3. Suspension Component Inspection and Replacement

Sub-steps:
1. Visually inspect control arms, bushings, and shocks for any signs of wear or damage.
2. Replace any worn or damaged components with OEM or high-quality aftermarket parts.
3. Reassemble the suspension components ensuring all bolts are torqued to manufacturer specifications.

4. Wheel Balancing and Alignment

Sub-steps:
1. Mount the wheel on the balancing machine to check for imbalance.
2. Adjust the balance by adding weights as necessary.
3. After balancing, perform a wheel alignment using alignment tools, ensuring both front and rear are aligned to manufacturer specifications.

5. Inspect and Replace Driveshaft or CV Joints

Sub-steps:
1. Inspect the driveshaft and CV joints for any signs of wear or damage.
2. If damaged, remove the driveshaft by unbolting it from the transmission and rear differential.
3. Replace with a new driveshaft or CV joint assembly as necessary, ensuring all bolts are torqued to specifications.
