Strange ABS problem
So lets see if I can put my issue into writing....
Have an 02 f250 v10, last summer replaced the steering gear box, havent had any issues til this spring.
Beginning of spring my ABS light came on during casual driving, wasn't to worried as the rear sensor often gets dirty and needs cleaned- cleaned the sensor and the light remained on this time.
While driving (and the light being on) I would at random get a very heavy vibration/shake from the front end and if I apply the brakes while that was happening the truck would pull real hard to the right, the shaking feels like a death rattle- like the ABS was firing and was using steroids, then it would go away. (the brakes would occasionally smoke a bit on the left front side afterwords)
So like that problem wasnt annoying enough, while trying to diagnose the problem the ABS light clicked off, and I wasnt able to recreate the vibration, but I noticed when I would apply the brakes, at say a stop sign, the brake would press in another inch or so (after already being stopped) and then I could hear a loud whine from under the hood.
The fun is these 2 problems seem to keep swapping positions- and im at a loss of what could potentially be the cause- (I assumed the 2nd problem where after stopping the break pedal going soft another inch and the whine could of been air in the system- I bled the brakes and no change)
Thanks for the help in advance guys!!

Might check the hub assembly for loosness and wear. In recent searches related to the hub I found it mentioned that as the bearing becomes loose/worn, that the sensor ring internaly can become misplaced enough to pop the ABS light. Another reason is the brake smoke you mention. With the hub going bad in a loose condition, I allso saw that the tilt on the rotor attached to the hub would cause the brake pads to touch in a tilted fashion. Might be why you feel travel in pedal as well.
Just throwing out a Ideas, Inspecting the front for loose parts sounds very important in your case. A helper pulling on pry bars, lifting wheel assemblies,and there for safety while tugging at the rig while off the ground, is all most a must.
