Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Transfer Assembly Inspection
- Raise the vehicle on a lift, and make sure it is supported securely
- Shift the transmission into N
- Make a reference mark (A) across the No 1 propeller shaft (B) and the transfer companion flange (C)
- Separate the propeller shaft from the transfer companion flange
- Set a dial indicator (A) on the transfer companion flange (B), position the dial indicator tip (C) on the top of the bolt (D)
- 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 TRANSFER ASSEMBLY )
- 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
