OK...I've got to ask

Why are you wanting to install a one-piece driveshaft? Am I missing the logic here? A one-piece driveshaft (non-slip) will create excess loads on your t-case output shaft, which is why they're probably telling you to replace the bearing first (so that it might last a little longer). As well, a one-piece would send shock loads all the way through your driveline everytime you hit a bump in the road.

Am I not thinking clearly here?? It is almost midnight, and I'm tired from studying....so please give me more info <img src="/forums/images/graemlins/smile.gif" alt="" />
