Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety when working on sensitive components.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Sub-steps:
1. Check tire pressure with a gauge; inflate to manufacturer specifications if needed.
2. Visually inspect tires for uneven wear or damage; replace if necessary.
3. If tires are balanced incorrectly, remove them and take them to a tire shop for rebalancing.

3. Driveshaft and CV Joint Inspection

Tools Required: Socket set, torque wrench, pry bar.
Sub-steps:
1. Raise the vehicle securely on jack stands.
