Transfer Output Shaft Installation Height Inspection/Adjustment

Note. If the transfer output shaft, the transfer output shaft bearing, the transmission housing bearing, the transmission housing, or the torque converter housing were replaced, adjust the transfer output shaft installation height with the 28.5 mm thrust shim.

1. Install the transfer output shaft (A) in the torque converter housing, and install the 28.5 mm thrust shim (B) on the top of the shaft. If you install a new 28.5 mm thrust shim, use the same thickness shim as the old one. Standard: 47.26 - 47.30 mm (1.8606 - 1.8622 in) Transfer Output Shaft Cutaway View
2. Install a new gasket (C) on the torque converter housing.
3. Measure the height (D) of the transfer output shaft installation between the surface (E) of the gasket and the top (F) of the 28.5 mm thrust shim in at least three places. Use the average as the actual height.
4. If the measurement is out of the standard, remove the 28.5 mm thrust shim and measure its thickness.
5. Select and install a new thrust shim, then recheck the installation height.

1. Warm up the engine to normal operating temperature (the radiator fan comes on), then turn the engine off.
2. Raise the vehicle on a lift, and make sure it is securely supported.
3. Remove the drain plug (A), and drain the transfer fluid (hypoid gear oil).
4. Reinstall the drain plug with a new sealing washer (B).
5. Remove the filler plug (A) and the sealing washer (B).
6. Refill the transfer assembly with the recommended fluid (hypoid gear oil) through the filler hole (C) until the fluid flows out. Use a SAE 90 viscosity hypoid gear oil, API classified GL4 or GL5 only. Viscosity: SAE 90: Above 0°F (-18°C) Transfer Fluid (Hypoid Gear Oil) Capacity: 0.43 L (0.45 US qt) at change 0.45 L (0.48 US qt) at overhaul
7. Install the filler plug with a new sealing washer.

1. Raise the vehicle on a lift, and make sure it is supported securely.
2. Shift the transmission into N.
3. Make reference marks (A) across the No. 1 propeller shaft (B) and the transfer companion flange (C).
4. Separate the No. 1 propeller shaft from the transfer companion flange.
5. Set a dial indicator (A) on the transfer companion flange (B); position the dial indicator tip (C) on the direct extension of the bolt hole center (D).
6. Measure the transfer gear backlash. Standard: 0.06 - 0.16 mm (0.0024 - 0.0063 in)
7. If the transfer gear backlash is out of the standard, replace the transfer assembly.
