Default Knocking/Rumble/Rattle Coming from underside of car.

Hey guys.

Its been there for a little while now and is starting to really get to me.

It happens generally when turning right, I hear a rumble/rattle/knocking which seems to be coming from the passenger side of the car.
Has anyone come across this problem before?

I own a bugeye.
Done the wheel bearing but no good.
If I had time I would have a real close look but im always at uni or work...

Any suggestions/feedback will be greatly appreciated.
Thankyou
Lukas

Exhaust rubbers might be stuffed or its not mounted properly.

It sounds to me like from the middle of the car.
Which is why I was stumped for idea's?

Im thinking it may be the exhaust mounted wrongly and knocking against the underbody.
When I give it some it makes the same noise sometimes aswell, which is why Im thinking that.

Might have to crawl underneath sometime.

Most common one I have had is the muffler hitting on the heat shield and it resonates through the whole car.. So it would definitely be worth a look.

If the exhaust is has been vibrating against the floor it will have been sending your knock sensor crazy too.......Just ask Fobz.

My zorst was bent up and hitting the body. Caused some shocking
noises at different revs. Also made my knock sensor go nuts at
high revs. Since getting if bent back away from the body the
noise has gone, and knock is much less.

Get a shop to see if its fouling the bodywork anywhere.
Pete are Carline on newcastle street fixed mine. Good bloke.
