help? 1990 f250 4x4

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.

My 93 F150 did the samething but there was nothing wrong.Went to 2 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 wear.

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.

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