Even when I take off from a dead stop, I can feel it as I accelerate. The sound is almost like someone hitting my car with a big hammer under the front end. Hitting slowly as I take off, to completely whacking the hell out of it as I go faster. The boots on my CV axles look fine, how do I check them for wear? I can turn the wheel sharply in a parking lot and accelerate, but there isn't any clicking sound. Also there seems to be a high pitch whining sound coming from the front end.
