Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery as a safety precaution.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers (if applicable) using a flathead screwdriver.
2. Loosen the lug nuts slightly with a socket set but do not remove them completely.
3. Lift the vehicle using a jack and secure it on jack stands.
4. Remove the lug nuts and take off the tires.
5. Inspect the tread depth and wear patterns for unevenness.
6. Replace any damaged or worn-out tires with new ones.
7. Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically 100-150 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure the alignment is checked and adjusted to manufacturer specifications.

4. Driveshaft Inspection and Repair

Sub-steps:
1. Inspect the driveshaft for any visible damage or signs of bending.
2. Check the universal joints for excessive play.
3. If damaged, remove the driveshaft using a socket set and replace it with a new part.
4. Reinstall the driveshaft and ensure proper torque specifications (typically 18-25 ft-lbs for bolts).

5. Suspension Component Inspection and Replacement

Sub-steps:
1. Visually inspect all suspension components including bushings, control arms, and shocks.
2. Replace any worn or damaged components as needed.
3. Reassemble any disassembled parts and ensure all bolts are torqued to manufacturer specifications.
