Engine help? - Hyundai Performance Forums

I brought my car in for regular tire rotation, balance, and alligned... shortly after my car shakes, but only above 75mph. What could this be?
A couple 1000 miles ago the mechanic told me I needed engine mounts, could it be that?

Also, what should my car be idleing at (RPM)? I just put a tach in and it is ideling at about 800, sound right?
Thanks?

A weight might have fallen off from the last balancing. Yes 800 is about right.

I would check the wheel bearings... I replaced my tires recently and had the same issue... it just gets worse over time.... I will be doing mine by the end of the summer...

It could be a halfshaft too. One of them showing signs of wear and is off balance.
