ok here's what my detent roller looks like now.




I'm about to change my upper bushings, and before I do I want to find out a couple things.


Should I even bother replaceing the roller? Does it being crooked like that make the door sag, or is it crooked because my upper bushings are shot?

 

The bushing inside the roller is worn out. Maybe you already know the new one comes with a pin and new roller. Yours is shot and needs to be changed.

 

yes, I know it's shot. The question is, does that cause the door to sag? I know people that do without the roller entirely

 

The roller, or lack thereof, has nothing to do with your door sagging.

 

Along with doing the top hinge there is a pin with bushings on the bottom hinge that should be changed at the same time.
