I had my ABD/TRACS module rebuilt, but I still get a noise(sounds like a ratchet when tightening a bolt) from the front of the car when I hit a sharp bump in the road. I thought this sound was related to my ABS. My ABS works ok and my warning light does not come on anymore. But I'm worried about this noise.

One possibility is a front strut mount. When one of them wears out, it makes a metal to metal noise at every pothole. Sometimes you can see the offending mount by opening the hood and bouncing the fender. There should be little movement where the strut joins the mount. Excessive movement in one or the other may indicate the problem.

It happens on mine too if speed is low..I get a twanging springy sound..I have Tracs, which uses tha ABS module, so I thought it's just the module being activated....if I hit the bump at higher speed, it doesn't activate.
