95 Cherokee A/C noise

My 95 Cherokee makes a train horn sound and vibrates at the drier occasionally. I had the unit serviced (complete evacuation and charged to spec). Any ideas what the problem is?

Originally, I was told that I had overcharged the system at home which caused this.

There is a baffle in the system somewhere, usually near the compressor, that is supposed to kill the resonance in the system. It sounds like perhaps a hose was replaced and that baffle was removed (it's a can-shaped thing in the A/C line)
