My car makes a fast knocking noise in the front of the car though this only happens when I let off the gas. When I accelerate there is no noise at all, then when I'm going over 40 or 50 and release the gas the noise starts and it will stop as soon as I accelerate. The noise seems to be in time with the rotation of the front tires. The noise seems to only happen after I go faster than 40 or 50, and it only happens when I let go of the gas.
