It's hard to figure out exactly what you mean by that, but it sounds like it's PROBABLY a loose or worn suspension part such as ball joint, strut or bushing. But I can't know for certain without listening to it and/or jacking up the front end.
Wheel bearing
Dead battery
No! Take it back to the mechanic, something is not right. Better yet, call the mechanic and ask him if it is safe to drive back to garage.
A 2000 Chevrolet automobile grinding noise can be caused by several things. The most common cause of a grinding noise is worn brake pads.
The whining noise in our 2001 2.2 cavalier turned out to be the a/c compressor. It ended up going out at about 120,000 miles. I would suggest having it serviced. I wish we would have had ours serviced.
Worn or glazed belt? Loose belt? Worn bearing on belt driven accessory?
I have a knocking noise near the water pump pully or idler arm pully on my 94 chevy cavalier 2.2 motor when its at idle, if i give it more gas the noise will go away do you know what this could be? i took off the tension idle pully and checked the bearing and it was fine.
Sometimes not all the time
A tapping noise is generally the result of a bad hydraulic lifter, plugged oil passage to the lifter, or bad tappets. Sometimes just changing to lower viscosity high detergent oil will cure it. Or "Any automotive oil additive with the word MIRACLE in it".
Low brake pads, misassembled brake parts?
if its when you are breaking it is possible it could be a rotor if you hear like a roaring or grinding noise coming from that side also could be a wheel bearing
