Vibration at low RPMs

I have been noticing that the whole car vibrates at low RPMs (like at 30 MPH, but my tach is broken...). It feels as though I have a flat tire for a few seconds before the engine speed increases. There is no bogging associated with the vibration, and this does not happen at idle. And yes, I have adjusted valves, replaced filters, checked air leaks; etc. Could it be a mount or bushing either in the engine compartment or back by the diff?

Could be motor mounts, engine shocks or transmission mount. It could also be flex discs or the center mount on the drive shaft.

Check your eng. and trans mounts, also the flex disks. take a look at the center support and bearing. If it`s the u joint, they are not replaceable, get a good used one.

Does the vibration only occur when you're moving? If so could it be a broken cord or did you throw a wheel weight off of one of the tires?
