Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Check tire pressure using a tire pressure gauge; inflate to the manufacturer's recommended PSI.
2. Examine tread depth using a tread depth gauge; replace tires if tread is below 2/32 inch.
Tools Required: Tire pressure gauge, tread depth gauge.

2. ABS and Traction Control System Check

Sub-steps:
1. Connect an OBD-II scanner to the vehicle's diagnostic port.
2. Capture and record any error codes related to ABS or traction control.
3. Clear error codes and perform a test drive to see if they reappear.
Tools Required: OBD-II scanner.

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Visually inspect control arms, bushings, and the strut assembly for any signs of wear or damage.
3. Replace any worn or damaged components as necessary.
Tools Required: Jack, jack stands, socket set.

4. Differential and Transmission Fluid Check

Sub-steps:
1. Locate the differential and transmission fill and drain plugs.
2. Remove the fill plug and check fluid level; add fluid if low.
3. Inspect fluid condition for contamination or metal shavings; replace if necessary.
Tools Required: Socket set, fluid pump.

5. Brake System Inspection

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads, rotors, and calipers for wear and damage.
3. Replace any worn brake pads or damaged components.
Tools Required: Socket set, brake pad gauge.
