Question about 2003 Chevrolet Impala

1 Answer

Cadilac conveter When I drive my car it has a loud noise it seems like if it was coming from the engine or the front of the car but I could also feel the vibration on the pedal. The faster I go the louder it sounds you can even talk because you can't hear anything. A couple of people told me that it could be the cadillac conveter so I was just wondering if that could be the problem

No, the catalytic converter is part of the exhaust and under the car,it would not make any sound if it was bad.you need to have your noise checked by a mechanic,just in case its a wheel bearing,it could seize up or even catch on fire if it is a wheel bearing

    If your car seems to lose power or shudder when you increase your RPM, or it takes a long time to accelerate, it may indeed be your catalytic converter. If you haven't changed your fuel filter in a while, you may want to do this too.

Loud humming sound coming from a ford five hundred when driving


That could be anything - from tire noise to bearing noise to the passenger in the rear seat! Where does the noise seem to be coming from - front? rear? left? right? engine? Is there anytime that the noise changes or goes away? Gets louder or softer? All these things help us to help you. Year and engine size are helpful too.

Driving noise, not from bearings


it could be center bearing, if its going bad it can also cause a vibration, make sure you have sufficient fluid in the diff as well, you can also get a noise and vibration from collapsed motor or trans mounts

I hear a loud grinding noise when i drive my car


Check front tyres & wheel bearings espesially the R/H/F. Feel tyre for high / low spots on inside & jack up & spin wheel if you get noise while jacked up it is not the tyres but wheel bearing or brake pads but more than likly a crook bearing by the sound of it. It needs to be tended to ASAP

There is no way to estimate cost until you know the exact case of the noise. See the dealer for a test drive so a tech can listen to it.

My 2004 Monte Carlo SS runs loud and it never did before. It's loud at low and high speeds, but seems to sound worse at low speeds. I do need a front end alignment (the car drifts to the left); would...


that depends on if you think the noise is coming from the motor, or the actual road noise that comes with driving , its probably the same at both speeds but sine you have less air and outside noise,, you hear it more at lower speeds. does it make the same noise when started but not moving? if you answer that yes, then its something else besides road noise, if it is no, then get your front end checked, it could be anything from a bad alignment to a bad wheel bearing, or bad brake ,

There is a very loud humming noise coming from the front left tire! plz I await your reply. Thks.


You probably have a bad tire or wheel bearing. Either the tire is cupped causing humming noise or grease inside sealed wheel bearing is burnt up. I would take front tire and move to the back of the car. Then drive again. If noise stays the same you probably have a bad wheel bearing. If noise moves to the back of the car than you may need to replace the tire. Most likely it is the wheel bearing, I replace them all the time at my shop
