From the '06 FSM for 4wd Torque: 88 N*m (897 kgf*cm, 65 ft.*lbf).
Propeller shaft is another way to say rear driveshaft in 'T4R land'. There's 4 bolts at the rear of the driveshaft that bolt it to the flange on the rear axle. There's the same deal at the front of the driveshaft. The torque is the same F&R.
