Disturbing Vibration

[joshm35]

ok, i have an issue. when i drive the car normally and a little on boost its ok. when its on full boost and i take my foot off throttle i get this disturbing grind/vibrate in my car which is noticable both by feel and sound. any ideas. im just hoping its nothing. a stuffed turbo would suh as i have only had the car for 2 weeks. any ideas, info would be good. im freaking out.

Josh,

This might be a big guess, but I would assume it might be a CV joint? Is it more like a click? Then this would be a CV.

Does it sound like it is coming from the back or the front?

How many K's has the car done?

[joshm35]

from the front mate. its done a touch over 140xxx

If its making boost it probably isn't the turbo, do you have an aftermarket bov or any other mods you know of?

Is that the only time it does it?

What's your location, I could have a listen if you're in Melbourne...

How much can you feel it?? Coz the bov does make a bit l of noise/ fart sound.. Not much vibration though however may be different with other ppls m35's

Just a suggestion as you say you here/ feel it when getting off the pedal!!

[joshm35]

def feel it under feet. mostly coming from driver side of car. yeah sounds like the noise you are describing. this one has me stumped

Im in brisbane mate. Im going to have a feel around to see if anything is loose. I kinda think it may be the gear box as it is doing it alot when it changes from 1st and 2nd when foot flat to the ground.
