My garage door shifted to the right, this causing the top door panel to hit the

I tried to shift the door back to the left side, but it would come back to the
right side over time. To fix it: Really simple, I put two zip ties around the
post between the door roller and the hinge its attached to, this keeping the
door from hitting the door glide. Now the door work fine, forever!
