Also, while the door is out I want to replace the wheels that the door rides on. I have foudn the wheels at Home Depot but my question here is how to remove the assembly that holds the wheels. On other doors I've seen the assrmbly wiht the wheel is fairly easy to remove, but on this door from what I've seen so far it looks like I have to disassemble the frame before I can slide the mechanism out of its channel. Can this be correct? It's going to be much more work.
BTW, this is a single pane door. I've been trying to find a manufacturers name but have not found anything yet (usually it is on the aluminum inside the two panes of glass). The only printing on the glass appears to just identify the glass.
