Problem Reported: Internal Transfer Case Problem on the 4WD models
February 27, 2011, 05:22 PM
<p>An abnormal noise may develop from the transfer case. At this time parts are not available to repair internal damage to this type of transfer case, replacement is the only option. It is not uncommon for irregular tire wear to cause a similar noise. Diagnoses should be performed to confirm the actual cause of the driveline noise. Tire noise can be reduced by rotating the tires at least every 5000 miles.</p>
