My car is making a terrible noise..help!!?

So, it's not a constant thing, or happens only when you hit the brake? Or, only when the car bounces? Then it is probably shock absorber / strut related. Can you bounce on the car when parked, and get it to make the noise? Could also be power steering, or rack-and-pinion steering cylinder. You need to have a buddy help, one to look and listen with the hood raised, and try different movements of the car to simulate the conditions it makes the noises, then follow it to the source. Grinding sound is usually brakes, though. You should have someone more knowledgeable take a look at it.

There are a lot of possibilitys, but some spots to look at first are to take your tire off, and make sure that you have not got a rock stuck in the brake rotor or backing plate. Another thing to check is that you have proper movement of the brake caliper, and that the brake pads are in good condition. It should have at least 1/8 inch of good brake friction material. If those are good, you need to make sure that the suspension and steering systems are ok, everything from the strut towers to the bearings to the steering joints. Good luck, but make sure to check everything out before any kind of trip. You could loose a tire or blow a joint and total your car.

Brake pad scraper alerts you to replace them.

Grinding could be a broken spring/strut and is very bad to get stuck out on the highway with.

Auto shop will save you the tow fees,

well first u should get someone to look under your hood to see if u have something stuck in ur engine or transmission if nuthing then look under your car and see if something is stuck under there if not then go to a local car repair

Take to the auto shop right way.

Your car is broken. Take it to a good mechanic and get it fixed.

pls have your center bearing checked. it may be worn by now. that's the only griding noise i can think of.
