4. Rotate the transfer companion flange several times to seat the tapered roller bearings.
5. Measure the starting torque at the companion flange (C) using a torque wrench (D) and a socket (E).

   Standard: 2.64-4.23 N.m (27.0-43.1 kgf.cm, 23.4-37.4 lbf.in) 

6. If the starting torque is out of the standard, disassemble the transfer assembly and repair it.
