I recently purchased a 2000 X5 4.4. I am replacing the front driveshaft as preventive maintenance, since the original driveshaft had some wear on the splines. My new longer front driveshaft lacks about 1/4" going back in. I have read that the transfer case can be slid back to give enough room. Has anyone on here done this? Can I just loosen the transfer case bolts and slide it back a little or do I need to do a lot more?
