Default Flat Bed Tow did damage!

I had my car taken to the shop on a flat bed tow truck. Watched the guy put it on, but did not drive all the way to the shop with him. Bad move. I am calling the tow company to get them to cover the costs of fixing it; they are reputable, and don't think I will have a problem.

When I picked up the car, I found a bent rear control arm, the heat shield folded up against the drive shaft (just in front of the differential) and after driving the car a couple of miles, the 'flat tire' warning coming on.

In thinking about how this could have occurred, I think it is all consistent with the truck hitting a bump, such as the entrance to a parking lot, and the truck bed swaying. This would have bent the control arm and pushed a wooden block under the car. The wooden block then hit the heat shield when it was backed off the truck.

Here is my question... So far the car drives OK, other than the alignment is clearly off, but the differential is not making any weird noises. When the heat shield was folded up, it was just barely hitting the u-joint just in front of the differential. Is right in front of the differential a particularly delicate spot? Need I be concerned about the differential beginning to leak oil as a result of the drive shaft being hit?

They hook the control arm then winch the car forward to create tension so the car doesn’t move...those are strong a*s winches...they’ll easily crumple the control arm if careless. The tow attachments should have been used.

Don’t know about the shield though.c unless the exhaust bottomed out and was wedged up against it.

The pinion seal is at the front, but that is a hefty piece of metal on double bearings. I’d think you’re fine there.
