I have a jeep grand cherokee that recently started to make a growling sort of noise and also rumble when I have to brake quickly from a moderate speed. The steering wheel doesnt shake but it feels like the whole car rumbles/vibrates. It has been driving me nuts. I changed the front and back rotors and brake pads and this did not solve the problem. Also changed the front brake hoses going to the calipers for a different problem that I was having. Im thinking some sort of a front end problem? I recently put new tires on and the outsides edges of the front tires are wearing. Maybe this has something to do with it. Any suggestions would be appreciated. Thanks.
