I was backing up onto ramps and at about half way up the traction between the wheels and the ramps exceeded the friction coefficient between the ramps and the concrete floor. You guessed it. The ramps literally shot forward to about the back edge of the doors with the rear wheels hanging just off the ground. No obvious damage except for some scraps and dents on the underside of the side rails. Get the floor jack out and jack up the car to remove the ramps. So far so good. As I had the drivers door open while I was backing up I now go to close it and discover to my horror that the door latch and striker are at good 3/16" out of alignment. I've lowered the striker plate so I can close the door but now I'm wondering if I need to take my baby in to see how much the chassis is out of alignment. That seems to me to be a pretty big shift in the rear quarter of the car. Damn it's always something. I'm beginning to think that "Murphy" lives at my house.
BTW, for those who responded to my earlier question about the a/c clutch not engaging it turns out that the a/c cycling switch was faulty. Discovered this when I tapped the switch and the clutch engaged but would cut out until I tapped it again. Cheap fix at $20.
