Yeah, but they do that to anything with fluid there. They puncture all trans pans, oil pans, and gas tanks as well!!!
Also, when they pick truck, suvs, etc, up with the fork lift they don't remove the driveshaft either. The bend every single one!!
When I was building my 86 Ramcharger I went up there to get a d/s from a 70's ramcharger so I wouldn't have to have one made to put a Dana60 rear in it. There were actually 2 or 3 of those years up there and low and behold.....every single frickin one was bent in half!!!
