4. Check that the center line of the bracket is at a right angle to the shaft axial direction.

HINT: 

If any vibration or noise occurs, perform the joint angle check as follows and replace the center No. 2 support bearing washers with ones of the correct thickness.

1. Stabilize the propeller shaft and differential.
   1. Turn the propeller shaft several times by hand to stabilize the center support bearings.
   2. Using a jack, raise and lower the differential to stabilize the differential mounting cushion.
2. Check the joint angles.
   1. Check the No. 1, No. 2 and No. 3 joint angles.

      *a	No. 1 Joint Angle (A - B)	*b	No. 2 Joint Angle (B - C)
      *c	No. 3 Joint Angle (C - D)	*d	90°
      *e	Straightedge	*f	Straightedge Contact Position

   2. Using SST, measure the transfer assembly installation angle (A) and propeller shaft assembly installation angle (B), (C) and (D).
      • SST: 09370-50010 

      Joint Angle

      Measurement Position	Joint Angle

      *a	No. 4 Joint Angle (D - E)	-	-

   4. Using SST, measure the rear propeller shaft assembly installation angle (D) and rear differential carrier assembly installation angle (E).
      • SST: 09370-50010 

      Joint Angle

      Measurement Position	Joint Angle
      	for Dynamic Torque Control AWD	for Dynamic Torque Vectoring AWD
      No. 4 Joint Angle (D - E)	1.86° +/- 1.00°	1.68° +/- 1.00°

      If the measured angle is not within the specified range, adjust it with center No. 2 support bearing washers.

3. Adjust the No. 1 joint angle and No. 4 joint angle.
   1. Select center No. 2 support bearing washers for adjustment.
