loud throbbing vibration even when in park on 2000 Focus SE wagon

I've got a 2000 Ford Focus SE wagon with about 90k miles on it now. For the last year it has been vibrating and humming or throbbing loudly. It seemed to only do it in the winter cold, but now does it all the time. The throbbing vibration starts just above idle and resonates inside the cab of the car so loudly at a low frequency that it will literally make you sick. If you get the RPM up high enough, it isn't that bad because the frequency of the vibration is too high to resonate, but you can still feel it in the steering wheel and if you put your hand on the front of the car anywhere. It feels like a car with no muffler. I've hear "exhast system", "flywheel" and "torque converter". Anybody have any ideas? I do not have to be moving. Just sitting in park or neutral will rattle your teeth if you get the RPM's above idle.

Failing motor mount. It gets worse, and is first noticed in the cold when the rubber is stiff, but as it gets looser is now noticeable all the time. The vibration has now damaged your exhaust system, which causes the noise. If you're lucky it could only be the donut (which separates the manifold from the exhaust pipe). The sooner you get it into a dealer or good repair shop (one able to do engine work), the better. It will simply cause more and more damage if ignored.

Don't believe there is a "donut" on the exhaust system for the Focus. Donuts were used on the old style exhaust systems which had a bell joint.

The Focus exhaust system is a follows: the manifold is connected directly to the catalytic converter which is connected to a flex pipe, which is connected to the front muffler, which is connected to the rear muffler..The flex pipe allows movement of the exhaust system as the engine moves. It could be an engine mount, the way to check it: block of wood on top of a floor jack and when it is making the noise slight jack up the engine (about

1 inch). If the noise stops its one of the engine mounts or the transmission mount that is bad, if the noise does not stop its something else. The only way to check and engine mount is when the weight is taken up on it.

Hey "Tune Up" Dave,

So you took the time to do a Google search to check up and see that I am right.

Yes my advise was from my many years of Auto repair and I am glad that you have finally acknowledged that.
