I have 3.5 inch of lift and my driveshafts are no where near hitting the skidplate, but when you are disconnected and your passenger side front wheel droops all the way while your drives side front wheel is pushed up into the fender well, the driveshaft travels up and to the right as the axle moves and this motion causes the boot on the driveshaft to come in contact with the automatic transmission unit. I don't like to disco for this reason. The lowering of the control arms does not address this issue at all, rather it just decreases the need for longer or adjustable control arms. With any lift over 3 inches you are going to run into this problem if you have an automatic tranny. From reading this, it doesn't sound like Rancho has done anything to correct this and I would be tentative to disco and fully droop the passenger side. In my mind the best thing to do is disconnect, droop the right front tire at intervals and look under the jeep to see how close you are to edge of the auto tranny. If you do hit your driveshaft on the auto tranny, you should not only replace your driveshaft, but also check the seal on the auto tranny case to make sure that you are not leaking oil. The driveshaft can actually knock off the edge of the case where the bolt is and this could lead to a leaking problem, which if not fixed could cause a need to replace the whole unit.
