Transfer Case Inspection and Service

Whenever servicing the vehicle, conduct a visual inspec-
tion of the transfer case. A few moments spent doing this
can help prevent further problems and down time later.
Inspect the transfer case in its entirety, especially the
main casting, for any cracks, dents or other damage.
Look for oil seepage or leaks around the drive shaft
flange mounts. Check all bolts for proper torque.
While the vehicle is under warranty, JLG does not recom-
mend the servicing of gears, shafts or bearings inside the
transfer case. Attempts at disassembly of these internal
transfer case items may void the warranty, cause dam-
age to other parts and to the transfer case casting (hous-
ing) itself.
