Initial Inspection and Diagnostic Overview

Driveline System

Inspection and Verification
Certain driveline conditions are also common to the engine, transaxle, transfer case, wheel bearings, wheels and tires and other parts of the vehicle. For this reason, make sure the cause of the trouble is in the driveline before adjusting, repairing or installing any new components.
1. Verify the customer concern by carrying out a road test of the vehicle.
2. Visually inspect for obvious signs of mechanical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the concern is not visually evident, verify the symptom and refer to the Symptom Chart. Symptom Related Diagnostic Procedures
