Defect
On four-wheel-drive vehicles, the liquid sealant applied to the mating surfaces of the input shaft case and output shaft case of the transfer gearbox was improperly applied on certain units, allowing transfer lubricant to leak. Continued use may cause the bearing supporting the output shaft to fail due to insufficient lubrication and, in the worst case, render the vehicle inoperable.
Corrective action
On all vehicles, inspect the transfer gearbox for lubricant leaks and install an O-ring at the mating surfaces. On vehicles where lubricant leakage has occurred, replace the transfer gearbox with the corrected part.
