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.

The car was missing with very low compression 45psi in #1. Did a leak down test but couldn't tell where it was leaking from. I just got the head off and one of the valves was burnt very slightly.
