Incredibly loud noise
 

Hi all -

First post here, before you guys jump to conclusions, I used the search feature and did not the find the answer to my questions. :(

I have a 2001 v6 GT with 80k miles and automatic (with tiptronic) transmission.

As of the past season (recently), every time I accelerate or pass over 3-4k RPM, I hear a HUGE vibration in the what *seems* to be the center front dash. It does not sound like it is coming from the engine, but again, I am not sure. It is very loud and usually lasts until the car shifts back into a lower RPM range. I don't really know into what gears this happens, but I am thinking gears 1-3. This does NOT happen every time I change gears, but once in a while or when I am more aggressive with the car.

I tried accelerating in neutral and the noise is not there. I am not sure what that is indicative of. However, I want to stress that the vibration is really loud...approx 80-90db.

Another question/problem I have is that I hear a rattling noise from what *appears* to be the front right wheel. The rattling isn't loud, and sometimes just sounds like a dull whistle and is constantly making that noise. Not sure what this may be.

Again guys, keep in mind I am not car savvy and would greatly appreciate any insight you guys may have regarding these problems.

Cheers,

EDIT: I also have an Injen CAI (not sure if that is a problem [I don't think it is])

My first thought is have your motor mounts checked out. These cars have weak motor mounts and they break. My 01 had a broken mount and it had a vibration and rattles. At first I thought it was bad struts/shocks or something but it turned out to be one of the motor mounts. FWIW At the time I was just buying the car it also had very close to the same milage as your car. The dealer fixed the issue for me so I cannot say which mount was the cause

Where the bst place to get eninge mount because i have a 2000 gt and i dont know where to get eninge mount from. And all the auto store was going to charge 117.00 for just one mount and i need to replace all of them... I need help finding some good ones

junkyard is probably the cheapest, not real sure if its the best. you could look on ebay, they appear on there from time to time

ya the car has really high miles on it it has 172xxx on it so i think the mount need to be change
