A while back I was bugged by a shudder on take off.
Don't notice it much anymore (maybe I've changed my driving habits to compensate).

Now at very low speeds (like backing up or inching forward),
I hear a "squeak squeak squeak" that sounds like it's in tune with the drive shaft turning.

Ujoints or center bearing ?
I'm thinking ujoints....

jack up the car and try to shake the drive-shaft. If you get some movement, then the center bearing is bad. If a u-joint is bad, it will normally be the rear one, around the diff so just shake and see if it is "klunking" around.
