Measure the transfer gear backlash.
Standard: 0.06-0.16 mm (0.002-0.006 in.)
If the backlash is out of standard, remove the transfer assembly, and adjust the transfer gear backlash (see REASSEMBLY ).
Check for fluid leaks between the mating surfaces of the transfer assembly and the transmission.
If there is a leak, remove the transfer assembly, remove the transfer cover, and replace the O-ring.
Check for fluid leaks between the transfer companion flange and the transfer oil seal.
If there is a leak, remove the transfer assembly from the transmission, and replace the transfer oil seal and O-ring on the transfer output shaft (hypoid gear). If an oil seal and O-ring replacement is required, you will need to check and adjust the transfer gear tooth contact, the transfer gear backlash, the tapered roller bearing starting torque, and the total starting torque (see REASSEMBLY ). Do not replace the oil seal with the transfer assembly on the transmission.

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
