Well, at low speeds, especially when slowing down, I hear a slow doop, doop, doop, but it gets really bad at highway speeds and when I'm cookin' at 65-70, there's a strong seat of the pants vibration. I can get it to go away some times by varying speeds, but for the most part, it gets worse the faster I go. I know my panhard rod was bent, but could that have messed up the rearend alignment and consequently bent my 'shaft? Thanks in advance!
