Total Preload

CAUTION: When measuring preload, the rotating speed must be set to 30 RPM.

Measure pinion bearing preload.
CAUTION: Check that the pinion bearing preload is within the standard.
Assemble the ring gear shaft assembly to the transfer case. Refer to "ASSEMBLY "
Install transfer cover to check and adjust each part. Refer to "ASSEMBLY ".
Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
Measure the total preload with the preload gauge (A) [SST: ST3127S000 (J-25765-A)].

CAUTION: Each rotational part should rotate smoothly with the specified gear oil.
- If outside the standard, disassemble the transfer assembly to check and adjust each part. Measure it with the transfer case oil seal and transfer cover oil seal removed when measuring total preload after disassembly. Then install transfer case oil seals and transfer cover oil seal.
