you have a few things that could still be wrong, jack up the front of the truck,
grab the tire in the 12 and 6 position and try to wiggle it, if it has play your balljoints are worn out.
if that is tight, grab at the 2 and 7 position and wiggle, if you have play, your wheel bearing may be going.
then grab the 3 and 9 position and try to wiggle, if it does, have a friend look from the front of the truck, and watch to see where the play is. normally you can see the play in a tie rod end by seeing if the one part moves before the other. if they seem good, look to see if they inner tierod is moving some before the rack does.
It would not surprise me if the rack was messed up after hitting the house. i believe there is an adjuster to tighten it up, but dont over tighten or the box will blow up
and driving down the road at 50 wont tell you shit by looking at it, no matter how smooth the road is, its going to wiggle, because the suspension is moving.
