Rumble

[oli_quick]

I've noticed a rumble coming (I think) from the drive shaft when I turn left at speed.

I am guessing it could be the drive shaft bearings or something when the chassis is being put under lateral force. Just wondered if this is a common noise, common fault or something I should get checked out ASAP.

The noise seems to come from inside the column the houses the drive shaft - so I assuming it is the drive shaft. Doesn't seem to happen turning right at speed.

Any ideas would be welcomed...aside from those expensive sounding reasons...

Not exhaust rattling on the chassis?....only needs a very slight contact, and some of these 'noises' can be very deceiving!

It does seem to be more of a frequency-type rumble, as opposed to a rattling.

Almost like a low rubbing (no pun intended ) noise.

try this first. I've had it many times. Cerbie exhausts move around a lot. I give mine a tweak (oo er) once a month or so.

mmm...i'd need to get underneath...I don't know Flat Stanley...and more realistically I don't have access to ramps.

Do people recommend taking it along to kwik fit for a problem like this?

Exhaust sounds like a good candidate. Try pulling the tail pipes sideways with the engine running and see if you can reproduce the noise.

Excellent - i'll give this a go then (donning my WWII gas mask to avoid immense CO hallucinations - leading to me trying to crawl into the tail pipes thinking, 'mmmmm...that would be a nice place to live...')

My exhaust needs adjusted nearly every 6 weeks and especially after very high revving, the high speed run at CREAM springs to mind. I found a slight adjustment with a crowbar just in front of the cats works wonders.
