A driveshaft apparatus includes a main driveshaft, a collar, and a driveshaft yoke, which attaches to a flange yoke via a cardan joint. The flange yoke is configured to attach to a transmission, transfer case or differential, where the torque from the transmission or transfer case is transmitted through the driveshaft to the differential or drive axle. The driveshaft yoke includes a stem portion having a reduced diameter relative to the main driveshaft, which may be in the form of a tube. The reduced diameter of the stem portion shifts the larger diameter further away from the flange yoke, and provides an annular space outside of the stem portion. The annular space provides increased clearance to a tool used to drive the bolts that attach the flange yoke to the transmission, transfer case, drive axle, or the differential. The stem portion may attach to the driveshaft via the collar.
