Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery to ensure safety while working on the vehicle.

2. Inspect and Replace Tires

Sub-steps:
1. Remove the wheel covers or lug nut covers using a flat-head screwdriver if applicable.
2. Loosen the lug nuts using a socket wrench and remove the wheels.
3. Inspect the tires for uneven wear, bulges, or flat spots.
4. If the tires are damaged or worn, replace them with OEM or recommended tires.
5. Reinstall the wheels and torque the lug nuts to manufacturer specifications (typically around 100-110 ft-lbs).

3. Inspect and Repair Drivetrain Components

Sub-steps:
1. Raise the vehicle using a hydraulic lift or jack stands.
2. Inspect the driveshaft for any visible damage or excessive play.
3. Check CV joints for signs of cracking or leaking grease; replace if necessary.
4. If any parts are damaged, replace with OEM components.
5. Reassemble and lower the vehicle.

4. Check Suspension Components

Sub-steps:
1. Inspect control arms, bushings, and struts for wear or damage.
2. Replace any worn or damaged components with OEM parts.
3. Reassemble the suspension system and ensure all bolts are torqued to specifications.
