Sub-step 2: Inspect each tire for uneven wear, bulges, or foreign objects.
Sub-step 3: Replace any damaged tires with new ones if necessary.

3. Suspension Component Inspection

Sub-step 1: Lift the vehicle using a jack and secure it with jack stands.
Sub-step 2: Visually inspect the suspension components (shocks, struts, control arms) for any signs of damage or wear.
Sub-step 3: Replace any worn or damaged components with new parts as needed.

4. Drivetrain Examination

Sub-step 1: Check the condition of the driveshaft for any signs of wear or damage.
Sub-step 2: Inspect CV joints for tears or excessive play; replace if necessary.
Sub-step 3: Re-torque all bolts to the manufacturer's specifications if components were removed.

5. Exhaust System Check

Sub-step 1: Inspect the exhaust system for loose or damaged parts.
Sub-step 2: Tighten any loose components or replace damaged sections of the exhaust.
