Description of Change: New bevel gears are available with a gear ratio of 9:29. Some internal gears within the transfer gearbox will need to be replaced in order to comply with the new gear ratio.
Note: The front differential and the rear differential bevel gears must be replaced when the new bevel gears are installed. The installation of the new bevel gear groups to the front differential and the rear differential will ensure that the proper gear ratio's is matched.Refer to Specifications, SENR5839 and Disassembly and Assembly, RENR3436 for the procedures.
