Sub-steps:
1. Check tire pressure with a gauge and inflate to manufacturer's specifications.
2. Inspect tires for uneven wear; replace if necessary.
3. Rotate the tires according to the manufacturer's guidelines (front to back, or cross-pattern).

3. Suspension Component Inspection

Sub-steps:
1. Inspect struts and shocks for signs of leakage or damage.
2. Check all bushings and rubber mounts for cracks or deterioration.
3. Tighten any loose bolts on suspension components to the specified torque values.

4. Drivetrain Inspection

Sub-steps:
1. Inspect the driveshaft for any signs of damage or bent sections.
2. Check CV joints for wear; replace if found faulty.
3. Ensure that all driveshaft bolts are properly torqued.
