ok guys heres my issue.......im having a loud vibrating sounding noise coming from the rear of my car. it only does it at high speeds above 80 mph...and when it makes the noise its not a constant noise it does it for like 2 seconds then goes away..... im positive its comming from the rear, it sounds like its comming from right underneith my trunk or around my trunk area....ive never heard a noise like this before its almost hard to explain how it sounds other than something vibrating very loud, i cant feel anything when it does this i can only hear it. any ideas? thanks

 

i feel/ hear the same thing sometimes, but at different speeds. sometimes at 25 sometimes at 45 sometimes at 85. i dont know i just brush it off until my tranny blows more like a hum than a bad vibration.

 

its the rear going dont launch the car before mine went i noticed this weird noise from the back driving on the highway then 2 days later bye bye ring and pinion

 

Have you check your spare and tools in the trunk? That might be 1st step if you haven't check it.

 

i dont have anything in my trunk exept my battery, and i drained my rear end to check and there wasnt any meteal shavings or anything....still think its the rear end? that would suck i just got my new transfer case. and i dont ever launch my car...it has maybe 5 launches on it total just alot of highway racing....

 

bump ok this noise only happends at 80-85 mph......doesnt make the noise at anyother speed and it does this no matter what...wot, coasting and braking.......

 

trunk monkey?

 

i wish lol i would pull his *** out and bust a cap in his *** lol.....

anyways back to topic....

any ideas? this ****s driving me crazy

 

What exhaust do you have?

 

new transfer case? hmmm.... I'd say check that out

 

there is a noise that comes from my trunk to... its the rod springs that hold the trunk lid up. they were vibrating together. only at certain speeds and type of road.

 

ok my transfer case, ive put 9000 miles on and its in the front of the car not the rear......and aboput the springs in the back i have removed them because i have a carbon trunk...........this ****s driving me insane i cant figure out what it is...

 

Exhaust, wheel bearing, tire perhaps.

 

ok i had a buddy drive and i took out my rear seat so i could hear it better....it sounds like a panel vibrating very loud like if you had subs in your trunk.....still cant figure out the exact spot its comming from but its definatley in the trunk

 

i would empty out my whole trunk; spare tire, tools, carpets(even the 1ns on the sides), then try the same thing again. have ur buddy drive n look again.

oh and also since u said it sound like a panel vibrating, check to see all the screws are fastened. n by all the screws i mean as many as u can find around there.(1/4 panel, inside and under the trunk).
also see if ur exhaust has anything to do with it. might have some loose screws.


a sound clip would be nice. somebody might be able to pinpoint the problem.

good luck
