s2000 buzzing noise in rear parcel shelf

[tamay_s2k]

hi guys
everytime i go past about 3,000rpm regardless of what gear
until about 6,000rpm i get this buzzing noise as if metal is vibrating, rubbing against something and making a constant BZZZZZZZZZZZZZZZZZ sound
it is very noticeable with the top up but a lot of the sound dies out when the top is down, or ive exceeded 6000rpm.
it sounds like the noise is coming from where the soft top meets the body of the car right under the rear window. ive checked all the bolts, even my boot has been tightened but still the noise is still there.
can someone please help me as it has been happening for like 4 months now and since its hitting winter, the top is up more often and the noise just drains my life.

[9000RPM]

u sure it's not clutch buzz thats causing the noise? cos all the symptoms sound like clutch buzz minus the fact its coming from the rear.

I have the same sound from the same RPM levels. Wish I knew what it was.

I thought it was from my hardtop because its begun happening since about then.

[tamay_s2k]

nah it aint clutch buzz
yea brad its so annoying
it got worse wen i got exhaust aswell
much worse.

Check your spare wheel. If the screw in clamp comes loose it can vibrate.

[tamay_s2k]

i did one better, i took the whole sparewheel out
does not change a thing :'(
its hopeless

You know another solution is a loud exhaust.

Maybe your parcel shelf is lose. Put some mats or something on your pracel shelf and see if it gets rid of the noise.

I have that, still no good. LOL.

And I don't have a parcel shelf, so its not that either.

[tamay_s2k]

same
my parcel shelf got removed after i put a sound system in the car
so nothing there is loose
i even tightened the softtop screws that u can c in the back, my boot bolts and everything
STILL THE SAME!!!
i got custom exhaust aswell so it is loud..decent loud. not unbearable like the invidia (im going by this on how much brad complains about his) lol

[jbird]

If the buzz is still there when you do a stationary rev then it may be your resonator?

Is there much clearance between your exhaust and any chassis parts.
Check the hangars, transmission mounts, engine mounts for excessive movement?

Dont over tighten the soft top bolts at the rear, as they are meant to be loose, and not firmly screwed other wise when it rains your drainage will be affected and coluld leak water into rear parcel area/boot.

[tamay_s2k]

yea when i got my exhaust done, they lifted it up a bit more then standard so my exhaust piping would be tucked away a bit but the noise was there before that aswell. well i think my diff has something to do with it since my left output shaft SNAPPED 2day next to my house at the roundabout whilst driving normally, out of no where my car started rattling form the rear and wen i turned at the round-about and put it bak in gear it just wen bang.. thats 2 in 2 months... 1st my right 1 and now my left . now i have to get the car towed and that fixed.
i think ill ask the mechanic to have alook at that other vibration while the car is on the hoist.

did u check plastic bits behind the seats? maybe somethings loose down there

[ludecrs]

Let us know how you get on. I'm keen to have the sound removed / taken care of.

And its not a plastic sound, so its nothing like that guys.

JBird could have hit it in the head with the resonator though.

Funny, I just noticed this same noise on Sat night, and have an am exhaust. Now that on Sunday I put in an HFC, its noticable at the same RPM range!

[dlai5552]
