I put mine in around Christmas...also replaced the steering gear box, and all my tie rod ends are good and ball joints as far as I know are good, and i have the stering box brace as well, and a 2" drop pitamn arm. my steering wheel's center still changes a lot. It will be a few degrees to the right, and then if i nudge a curb, it will go a few degrees to the left...the truck obviously did this before, just like they all seem to...We welded up all the cracks in the frame, but it seems like the weld in brace should eliminate pretty much all of the frame flex in the trcuk...do your trucks do this too? Any ideas would be great, thanks. Oh yeah, the truck tracks pretty straight down the road no matter where the steering wheel is.
