Hi every1 I have just purchased my new 2004 350z and just wondered if any 1 could help me with a problem. The inside of the cab seems to vibrate when accelerating you can hear the windows shaking lol the vibrating goes when you floor it and it smooths out ?? Also is normal for the noise to pop your ear drums when driving :/ It does say on the last mot that the sound guard underneath is corroded could this be it ?

 

Congrats........... Was it like this when you bought it?? Is it throwing any codes? Uh no, it's not normal for the car to pop ear drums while driving. I also fail to comprehend the bold part. Rewrite please.. So this intense vibration is always there, except when you floor it??

 

Hi thanks for your reply! Yes it most of been their when I purchased it but didn't notice on the test drive totally my mistake the vibrations are not their on idle nor are they their at high speeds just when driving slow in low gears, and yes my ears are ringing after the drive lol could that be the corrorderd sound baffle guard ?

 

Maybe your mid-pipe is laying on top of your crossmember...

 

The vibrations could be a number of things, from bad bushings, to bad bearings, suspension components, exhaust linkages, end links, out of balance wheels, etc. etc. You're going to need to get under the car and check everything. Pay attention to the rear differential bushing as those are prone to failure after so many years.

By the way...
