I recently just bought this explorer, and while I was test driving it, I never experienced the problem, but once in a while, the vehicle will shake when taking off from a stop, then goes away second or two later. I just put new tires on it, and it was doing this problem before that.
Any ideas? One friend said could be rear end (or rear differential?) going out, and another friend told me could be rotted engine mounts.
edit; When the vehicle shakes it similar in a manual vehicle how you let off the clutch too much but not put enough gas down without killing it.
