Pigeon toed ttb

[503sp01]

i have a 91 f250 with a ttb and a 4” lift and when I back up the tires go like /\ is there any way to fix it I don’t see a sas swap in my near future

My friends truck did that, his was due to alignment, my bronco does the same thing but when driving straight the wheels stay straight. Sometimes is a sign of worm bushings or steering components/alignment. Pretty much all the ttb trucks I've seen do this

Yes it is very common when backing up. Do they sit normal going forward? If so, send it.

With my 4" lift it did that until I did a full alignment with adjusters that had a significantly larger adjustment. A friend found the adjuster and we spent a long time leisurely doing the alignment to get it correct. It has a very small pigeon toe when backing up, but you really need to be picky (me) to notice it. An alignment like this is a lot more expensive and requires a tech who knows what they are doing to get it correct. We used his bosses alignment rack after hours so it was pro-bono. We each help each other as we can.

I will check everything out it’s very bad backing up I have to move the wheel back and forth just to keep backing up

Mine is still doing it a bit after all new front end components (tie rods, box, balls, radius bushings, I beam bushings) and an alignment. I was almost about to post this exaxt question haha

I think they're built that way for some reason.

Its because its a Ford not a Backwards ! Lol
Whats a TBB ?

"TTB" = twin-traction beam.

They do this because of toe. When you back up the wheels naturally want to pull away from your line of travel. This pulls any slack from worn steering compenents causing more toe, plus it flexes the front suspension like it was carrying a heavy load. Due to the articulation of the split axle (when loaded) the front wheels are no longer vertical (camber); when added to the toe angle the truck looks cross-eyed.

The fix is to replace all wear parts to minimize the effect, swap a D60 solid axle, or I guess you can reverse the toe angle for that perfect look when backing up

swap a D60 solid axle,

The real fix...

The camber change is an inherent property of the split axle style design. Swing axle VW's and vintage Mercedes are a good example of how this works . Good explanation by mblaney

Basically... replace worn bushings and such and ignore it. What matters is going /forward/ what the toe angle is.
Going backward? Not really an issue.

If it is properly aligned you will get minimal "pigeon toe" when backing up. It took several tries and a very committed friend to properly align my TTB. It has a very slight, almost unnoticeable, toe when backing. When it had the noticeable toe when backing it also wore tires more quickly in day to day driving. In other words, if it has a noticeable pigeon toe when backing IT IS NOT PROPERLY ALIGNED!!!!!!!!
