To install:
  1. Install the driveshaft into the transfer case. Install a new flex giubo coupling at the front differential.
  2.  

The arrows on the giubo coupler must face the arms of the flanges.

  1. Install the bolts and tighten the M10-8.8 bolts to 35 ft. lbs. (48 Nm) and the M10-10.9 bolts to 52 ft. lbs. (72 Nm). Hold the nut or bolt at the flex giubo coupling side and turn of the flange side. This prevents stressing the flex coupling.
