Important: Transmission oil circulates between the transmission assembly and the transfer case. In situations where transmission related failures circulate debris into the transfer case, the transfer case must be disassembled, cleaned, and inspected for damage.

1. Position the transaxle so that the case side cover is facing down.
2. Install the final drive sun gear shaft (689).





3. Notice: The park gear thrust bearing (695) must be retained in the park gear (696) when installing the transfer case to the transmission, or damage may occur.

Use J 36850 or equivalent in order to retain the parking gear thrust bearing (695) to the parking gear (696). Install the parking gear thrust bearing (695) and the parking gear (696).

Install J 44472 (2) onto the transmission.
Tighten J 44472 to remove end play. Hand tighten only.





7. Measure the distance from the case mounting surface, bottom of the gauge bar (1) to the top of the final drive sun gear (697). This measurement is dimension A, refer to Transfer Case Selective Washer Specifications.
8. Remove the gauge bar (1) and J 44472 (2).





9. Install the gauge bar onto the carrier.
10. Measure the distance from the bottom of the gauge bar to the transfer case. This measurement is Dimension B1.





11. Measure the distance from the bottom of the gauge bar to the thrust bearing (1). This measurement is Dimension B2.
12. Subtract Dimension B2 from Dimension B1. This Dimension is B.
13. Remove the gauge bar from the transfer case.





14. Remove the final drive sun gear (697).
