[QUOTE="Chris, post: 425473, member: 1"] It is suppose to spin. Though your passenger axle shaft is disengaged from the vacuum, your driver is, which will cause free movement in the driveshaft. Even if you have a vacuum that is locked all the time, it will make no change. You transfer case only adds the actual output when the shifter is engaged, which causes the shift fork to move over and engage the 4WD section of the splines on the tail shaft (in laymen terms). That is why you feel no difference while being in 2WD. It is perfectly normal. Vehicles that have manual locking hubs will normally notice that their driveshaft does not spin, it is soley because of our auto locking hubs. [/QUOTE]
