Can wheel bearings affect toe/alignment?
Hey guys, it's been awhile. I've retired the truck in my sig below and it's now become a pure toy/weekend warrior. Before I retired it, it was out of alignment so I replaced the following:
Upper + lower ball joints
Inner + outer tie rods
Pitman arm
Idler arm
Driver CV axle (snapped it while yanking someone out)
Parts were all from Autozone, nothing great.
I cut the outer tie rods as per Fabtech's instructions below:

I've done this job at least a half dozen times on this truck and had it aligned without any trouble. This time however, the truck just will not align.
I don't have the alignment specs on me right now (I will later today), but I believe the truck has a lot of negative toe - the front wheels are pointing out away from each other pretty badly.
I took the truck back from the alignment shop, cut the tie rods even more thinking perhaps I didn't measure enough, and I believe it helped a little, but it's still way, way out of alignment. I know I have to have cut off more than the recommended amount by now, so I don't want to cut any further.
The only things I haven't replaced are the wheel bearings/hub assemblies. It's been a month or two since I've worked on the truck, but from what I can remember, there wasn't any obvious noise or play coming from either wheel bearing/hub assembly. Could these be the culprit? Any other thoughts? Looking to get this truck fixed before the next RYC event. Thanks!
Edit: Also forgot to ask, if there are ABS cables up front, the truck has 4-wheel ABS correct? I'm looking on RockAuto, and I see they have wholesaler closeout hub assemblies for less than half the cost of the normal items, but they're 2-wheel ABS. There's really nothing wrong with running these 2-wheel ABS hubs on a 4-wheel ABS truck is there? Hell the ABS wire on the passenger side has been snapped for months anyway, so this would really be no different.
