Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Check tire pressures and adjust them to the manufacturer’s specifications.
Inspect tire tread for uneven wear or damage. Replace tires if tread depth is below 3/32 inches or if they are worn unevenly.

3. Traction Control System Check

Tools Required: OBD-II scanner.
Reconnect the battery and turn on the ignition.
Use the OBD-II scanner to check for any existing error codes related to the traction control system. Clear any codes and perform a drive cycle to see if they return.

4. Suspension Inspection

Tools Required: Socket set, torque wrench, pry bar.
Lift the vehicle using a jack and secure with jack stands.
Visually inspect suspension components, looking for cracks, broken bushings, or other visible damage. Replace any damaged components.
Tighten suspension bolts to the manufacturer's torque specifications.

5. Differential Fluid Check

Tools Required: Socket set, fluid pump, fluid for the differential.
Locate the differential fill plug and remove it.
Check the fluid level; it should be at the bottom of the fill hole. If low, use a fluid pump to add the appropriate differential fluid until it reaches the correct level.
Inspect for leaks around seals and gaskets.
