Transfer Case: Testing and Inspection

DIAGNOSIS AND TESTING - TRANSFER CASE
Before beginning repair on a suspected transfer case malfunction, check all other driveline components beforehand. The actual cause of a problem may be related to such items as: front hubs, axles, propeller shafts, wheels and tires, transmission, or clutch instead. If all other driveline components are in good condition and operating properly, refer to the Diagnosis Chart for further information.
