After the roads were plowed, some of the compacted ice/snow fell into the road. I accidentally drove over the pile and it busted up beneath my vehicle. My vehicle drove fine the rest of the day. The next morning I start the vehicle and began to drive and it starts making a loud clicking noise when I accelerate. The noise is NOT present in "Park" or "Neutral"; only when I put it into gear, and grows louder as I accelerate. This is an Automatic Transmission and when the gear shifts the noise gets quieter but soon grows louder as I continue to accelerate.

I stopped the vehicle after I heard this noise and checked underneath. I found a frozen slab of ice in between the skid plate and my front driveshaft. I broke it free but the vehicle still makes the noise. I'm afraid where the ice had froze against the driveshaft when I started the vehicle the next day that it may have damage my driveshaft and/or transmission, I'm not sure! The noise seems loudest near the very front of the driveshaft just below the actual engine.

Put it in drive, hold your foot on the brake pedal so the vehicle doesn't move, then raise engine speed as though you were going to accelerate. If you hear the noise, that is due to an exhaust leak. Water may have seeped into a flexible joint overnight and froze, expanding the flange. That is typically not a very involved repair.
