I recently had my drive shaft apart for a rebuild at which time I replaced the center support bearing. I had the old one removed and the new installed by the driveline specialist who also replaced the u-joints and balanced the whole thing. Everything works fine except that I get a whine (in all gears) that seems to be coming from the center bearing. Is there anything that can be done besides replacing the bearing again? Is there any type of alignment that can be done? I have had the car up on jacks and crawled under with the drive shaft spinning at it sure seems to be coming from the bearing. Also seems to get worse after it heats up. Any words of wisdom?
