I'm new but I have looked through many pages to find a problem like this. I have a 96 Z24 automatic with the 2.4 L. When I am going about 45 miles an hour and step on the gas to pass or accelerate the car pulls hard to the right, then when I let off and it downshifts it pulls back to the left. I have reved the engine while looking in the engine compartment and it does the normal rocking but nothing seems loose. The car also does not pull hard one way or the other when braking so I don't think that is the problem. Could it be a half shaft (axle), or a wheel bearing?
Thanks for helping,
Kerry
