On my 2004 Acura Mdx, someone sideswiped on my car while it is parked a few months back and ever since then I noticed shaking on the steering wheel when driving at high speeds in the highway. I tried rebalancing the front tires and it still have problems (though it is a little better than before.) The rear tires are fine. Not sure what I would look next, and how would I ask the car repair guy ask how to fix the problem. I heard that it might the CV joint might be bad, but not sure how much it cost to replace it. Anybody have any advice, I would like to know. Thanks.
