I was driving down a dirt road a ways back in the woods going maybe 10-15mph, hit a washout that I forgot was there and the truck bounced fairly violently. After that it vibrated and growled, and I wasn't able to go very fast. It had sheered one mount off, tore the rubber in half, and cocked the engine to one side a little. Went to the yard, pulled one off a 2wd and was done with it shortly. I've heard the 2wd ones don't line up the same, but I've used them a couple of times without any fitment issues.
