When I back up the front tires look they want to lay down. Does anyone
have any idea why they do this?

Common on independent front suspension. My old Bronco looked like a pigeon
toed cowgirl after backing it into a parking space that required lots of
turning the steering wheel.

No need to worry.

frontend shops and still couldn’t find anything.The top of my front
tires was in futher than the bottom but never had any abnormal tire

It is NOT a indepensant front end though, it is a primative knock off
called the TTB (Twin Traction Beam which is basically a D44 with a
pivot hinge in the middle of it) and wildy changing camber angles and
funny tire wear is its trade mark due to design limitations. ANY time
the suspension deflect/ moves up or down the chamber "angle" or
wheel will change a lot. It is not at all like a true IFS that GM
uses and even ford finally give that design up quietly recently too.
The only "cure" there is for that problem is to trash the front end
and replace it with a solid front axle or live with it.

TTB IS considered an independent setup.

It's just made that way. The steering toes out on turns (designed that way),
and when you back up, it's toed in (so to speak) and the tires kind of crawl
together. As it happens, the twin I-beam suspension allows the tires to fall
over "extra far" by raising up in reaction to the tires.

Mine doesn't do that if I back straight up. But anyway, just ignore it.

I should have added, when I back straight up, they just fall over the
opposite way. I think maybe that's what Shakes73 is talking about.

You're right, but it's camber you're talking about.
