RUMBLING NOISE WHEN STANDING STILL WITH BRAKES DEPRESSED AND CAR IN DRIVE

1994 Geo Prizm • 122 miles

I have a rumbling noise that happens whenever I apply the brakes and come to a stop. It makes the noise when the car is in gear but stop if I put the car into neutral. The steering wheel also vibrates which I'm sure is an unrelated problem but I though was worth mentioning.

I put new brakes pads and rotors on the car 5/1/12

Thanks,

Have you checked all the engine and transmission mounts?

No I haven't where are they located, how many are there and how do you tell if they're are bad?

Do you have the 1.6 or 1.8L engine?

There are at least 4 mounts thay are rubber and metal used to isolate engine vibrations. Thay some times will brake or get week and mis align the engine and alow parts of the engine and or transmission to be in contact with the body of the car. To check them you would start with a visual check and then pry on them with a large bar checking for excessive movement.

The mounts are still in the same place for that engine as well.
