My 2001 9C1 Impala developed a mild vibration upon acceleration about a month ago. It is smooth as silk while cruising or decelerating, but if I try to accelerate, especially on a hill, it now feels like I am driving on rumble strips in the road. I am not sure where to begin to troubleshoot this. My first thought is the drive axles.
I read all the forums on here about this, and saw several others with this problem over the years. There were several theories, and a few success stories, but those who were stumped and were taking their cars into the shop never posted what the results were.
My question is, what was the prevailing reason for this? Am I more likely to have to replace some sort of motor/tranny mount, or the drive axles?
i know i had tires that would rumble while reg driving (a little) but when you got on it they would be all sorts of bad. but they where new tires that pep boys screwed up on. i would tend to think its the cv. check the boots for cracks or leaking axle grease. this would point to a bad cv and replace it.
some say to replace both at the same time idk why i like to save money and take a 50/50 chance and save some cash

Sorry if i'm an a**hole, but i tend to speak whats on my mind and the truth as i see it.. May not be right but it seamed right.
Just had this problem - vibration or shimmy under acceleration from about 55 - 65 mph (no vibration when coasting at those speeds). Had the left half-shaft replaced and the problem is solved. Had the same problem several years ago and it was the right half-shaft. I'm wondering if there is another issue that is causing this to happen to the half-shafts.
