the yoke is the front of the DS that goes into the back of the transmission
O_O
to me it seems like he means the 4 bolts holding the DS to the rearend, i use the good'n'tight method, actually i just zip them down with an impact. i dont sit on it clunking it though, just zip em down and a few hits does em good.
The 4 Bolts that hold the Driveshaft to the Companion Flage is 71-95 Ft. Lbs. Make sure you use new Bolts that have the Yellow Lock Tight, also make sure you line up the match marks on the Driveshaft and the Companion Flange.
