what's that noise?

No vibration? None at all?

That is a very low frequency - maybe a heat-shield from the exhaust system, or it hitting the frame of the car somewhere? Or a soft motor- mount causing more-or-less the same thing at a certain RPM?

If there is vibration, the answer _will_ change.

No vibration more than usual. It's very possible that one or more of the motor mounts is bad. There's a distinct THUNK when starting from a standing start, which I've been told is a sign of a bad motor mount. The front shocks are shot.

If there was vibration, what could the answer be?

Is there an online repository of vw rabbit noises?

Thanks, Reid

Mpfffff.... So, bad strut/shock mounts, bad motor mount - that has it covered all-in-one. Start with the mount, then do the shocks - very preferably at the same time. Try stopping hard with bad shocks - you might find yourself three lanes over by the time the front-end stops bouncing. This is life-safety stuff. Until then, no kids, no SOs, no one but yourself in that vehicle - and only then at low speeds on local roads with nobody around you.

As to what the answer could be if vibrations: Bad wheel-bearings or CV joints, bad ball-joints, tie-rod ends - AKA drive shaft or suspension parts. Also potentially life-safety stuff.

At 24 years old this car has 'needs' - fail to meet them at your peril and at the peril of those around you.

Gah, I wish I'd known this sooner. Just returned from a long road trip where I was driving at 100KPH+ for days on end. Just me in the car though, fortunately.

OK, will get on this pronto. How difficult is it to replace the motor mount(s) ?

I hear ya. Thanks muchly for the info!
