Is this normal?
1990 f-250 7.3 idi 2x4 long wheel base extended cab. My truck seems to set level but the front tires lean inward. The bearings are fine and everything seems to be in order under the front end. I think the front springs may be a little tired, though I am not sure. Some kind of input would be nice because its been aggravating me since I bought it. Drives great though.

I will get a pic up as soon as i can. I'm on campus now. But the top of the tires lean inward. Kinda like this /---\ with the slashes being the tires. and the dashes being the bottom line of the truck.

Uhhh... there is no torsion bar on an early 90s F250, but I guess if the ball joints are completely worn out they could affect the way the tire sits. Mine have no play in them though.

Another common item that can cause this are worn spring and shackle bushings.
My truck has the same problem and I want to fix it, so far the tires seems to be wearing ok, which makes no sense at all to me.

I haven't seen any uneven tire wear yet either. Kinda puzzling? I will probably look into making some spacers for it. Sounds like a good cheap fix. My ball joints aren't worn out. Everything is rigid.

When you notice your tires like this /---\
Was it just after backing up?
Camber angles change alot on these trucks, usually backing up makes 'em go like this /---\
Then when you drive forward, they return straight |---|
I work on Fords alot, and I actually see as much 2wd Fords, company vans/trucks running around like this /---\ than this |---| and what I learned by working on them, is the camber adjuster on the top ball joints, with the bumps/vibration, can turn overtime and changes camber.
Very very very rare to see old older King Pin twin I-Beam setup running around like this /---\
Even my motorhome, 1987, 160k miles, original springs, carrying alot of weight, and the front sure bounces up and down alot, and I had it aligned earlier this year cause the factory tie rods were done, and passenger side camber is 0.1* and driver side is a perfect 0.0*, it is a King Pin front end.

His is a 1990. Wouldnt he have the Dana 60 front axle? I know my buddy's 95 F-150 did the /---\ after he went into a ditch and it was his axle itself that wore down over time, granted he had the Dana 50 TTB.
