As I look at this and understand it better - I may just need to replace the 11/2" wheel? You know better than me. If so, these are nylon wheels would a steel wheel be better? Thank you
swapping door hardware I believe the only piece I need is the nylon 1 1/2" roller with the ball bearings. The present roller doesn't have an axle per se but two rivets built on to the roller? An axel could work as long as it had an end that held in place on one side and was only as wide as the two holes in the bracket (if any of this makes sense to you).
BTW - if you find some I'll take at least 4 and as many as 8.
