Rocks in the skid plates
 
My 2012 JGC Overland Summit gets driven about 15 miles every day over a fairly rough, steep, gravel/dirt road. In 4 months, it's gotten two rocks on top of the skid plates.

The first rock was maybe 4" x 2" x 1" and caused quite a bit of consternation - it made nasty clunking noises and then got jammed between the transmission and the skid plate which caused the whole car to vibrate. We didn't realize it was a rock, took it to the dealer, and the mechanic finally found the rock on the second visit (he at first thought it was a "major transmission problem").

The second rock was slightly smaller and I was able to fish it out by cranking the Quadralift suspension up high and groveling underneath.

I wrote this for two reasons:
(1) If you hear clunks or get nasty vibrations, it might just be a rock on the skid plates.
(2) Has anyone else had this happen? I suspect that I might be pulling rocks out regularly. I've never had this happen on other vehicles.

I haven't noticed it yet but have not been on many gravel roads yet. I suspected this might be a problem though when I first bought the vehicle and crawled under it. I already plan on taking the skid plates off once a year or so and cleaning them out.

I've had lots of small rocks under the skids, but nothing of that size. I've been able to push them out pretty easily

Yes, I've had that happen once in ten months and 11,000 miles. I have a 1000-foot gravel driveway that's not in great shape. One day I started the car and heard the same "major transmission problem" sound. The service department at my dealership took only a couple of hours to figure out it was a rock jammed between a skid plate and a casing. There was no damage.

I took my Summit off road last weekend up in Santa Barbara (Big Caliente Springs)

Tire kicked up a rock the size of a small charcoal briquet. I actually heard the strike when the tire kicked it up, but didn't think it landed on top of the skid.

On the way home I had this metallic banging noise over any bump and I knew that rock was the one that was making the racket.

I ended up getting the rock out this morning and it's sitting on my kitchen counter.

Luckily I didn't have to remove any of the skids, I just banged my hand on the skid plate until the rock ended up at the rear and I pulled it out (luckily my driveway has a pretty good angle so that made it easier)
