Driveline Vibrations?
I've had some bad vibrations developing on my 04 AC. Both cruising at highway speeds and during hard braking. The culprit? A bad center support bearing in the driveline. And its not the bearing that goes out, its the giant rubber bushing that cushions the bearing. It was pretty easy to change, and made a world of difference. Its like night and day. Brand new smooth. Whats funny is all the u-joints looked and felt new. Its only got 50K on it.
And while I was under the truck, I also lubed my shaft.
