You guys have been great help in the past and I hope someone can shed light on this problem. I have a terrible noise in the front end of my 2002 Impala LS. I have had front brakes, rotors turned, new bearings, new tie rod ends, 4 new tires, front and read alignment. This noise is a crunching sound and seems to be rhymic with the slowing of the car when I brake. I have had this to 4 mechanics and not one can find a problem. Someone mentioned to me to have the harmonic balancer checked. Any ideas?

Thanks

Could be in the back also,bad strut plates and are a very common problem.Which Engine,the 3400 or the 3800?

A friend of mine had a noise similar to what you describe and the noise turned out to be the starter drive being worn and hitting the flywheel when slowing down,just a thought.

The engine is a 3800. I have now been told that I have two motor mount bolds broken off and need replaced. Could this cause the problem. I can actually feel a loseness in the brake pedal. I am at wits end with this car. Thanks for your input.

I am having a similar problem on my 03 3.8 impala ls. When I turn at low speeds I hear a crunching noisy come from the front end. I plan on looking in to it in the next few days. But you say you're noise is only when you are slowing down or stopping?

When I turn my wheels at a slow rate especially, I have a rubbing noise. when I brake I have the crunching nosie. I do think some of my problem is the motor mounts. But, there is definately an issue with my braking system.

mine is only when turning (not braking). If I find out that the noise is on my car I will let you know. Maybe it might help you solve you're problem.
