installed a 5.5" rough country lift a few months ago and also changed control arms, hubs, cv axels, and brakes upfront. install went smoothly as possible but I'm experiancing a rub/ grind upfront around 35mph, changed hub after rubbing was heard and it did nothing. been hunting it down since I heard it and I finally think I have a breakthrough, got under the truck and looked around and I noticed both torsion bars are hitting the lower control arm in the through hole. the drivers side isn't hitting while parked but I can see a huge gouge and the paint missing on the top right under the rear through hole on the control arm. the passenger bar is constantly touching the rear hole too. does this mean the torsion bars are bent? I know they are made to take a lot of tension but I've never seen them rub the control arms. noise its making is driving me insane and its damaging the torsion bars. any ideas?

Did you ever figure this issue out? Having the same problem with my passenger side.
