Garage door bar
I am curious as to the one piece torsion tube on my garage door.
It has a single torsion spring on the left with two cable drums on each end.
It was making a clunk sound when near to all the way close.
I disconnected the door from the opener and couldn't find any problems.
I lubed the rollers, spring and the torsion tube where it travels through the cable drums and has seemed to resolved the problem for now.
Anyway, the torsion tube travels about an inch to the right when open and back to the left when closed. These directions of travel are from inside the garage facing towards the road.
I've never really noticed this before and was wondering if this is normal or an indication of something about to go wrong.
