2. Remove the ring gear shaft assembly from the transfer case housing.
3. Turn the connecting flange back and forth two or three times to check for extraneous noise, jamming and wedging.
4. Rotate the connecting flange at least 20 turns to check that the bearing runs smoothly.
5. Using a special tool (A) (ST3127S000) measure the moment of resistance to rotation of the drive gear bearing.
Attention. For smooth rotation of all moving parts, it is necessary that they be lubricated with gear oil.
Note. If any deviations from the norm are found, it is necessary to remove the gear shaft from the transfer case for inspection.
