Yep, about 90 ft.lbs. is what I use. Apply sealant to the splines, install the "companion" flange, install washer and nut, torque to spec, then stake the flange on the nut into the groove on the shaft to lock it in place. Companion flange is "Toyota-speak" for the transfer case output flange and the pinion flange. Between the "companion flanges" is where the "propellor shaft" (i.e. driveshaft) is attached.
