Yes,
That's the first thing I'd do. Also regular tire balancing isn't a bad idea. As the tire wears you sometimes get an unbalance. Not only that but the wheel weights fall off from time to time, maybe that's what happened in your case. If you brought your Element into my dealer and I got the repair order the first thing I'd do to try and repair it would be to balance the tires. Usually that will fix it.
