@Carlos G !! (and others)
I've written rework instructions so that anyone will know what they need and then do the rework in an afternoon, provided you have some rudimentary tools (nothing fancy).
The parts are readily available, and the Aurora MM-5 Heim bearings I prefer are on Amazon (for less than I was paying at Tek Bearing). The last ones that I bought were made in Canada. Avoid any and all of those listed for under $10 bucks each - They're pretty bad quality and will bind up in short order. They're also a bit sloppy - something you're trying to avoid.
I've attached the rework instructions, with parts list, to this post so you can see what you need and it has a source link to the bearings. Everything else is available at your local ACE Hardware store.
I used the male threaded bearing, making it adjustable in height, but the female version works well if your bar height is similar to the height of the bearings (there is a set of dimensions listed that you'll need to make to know what to buy).
The spacer tubes are cut from a length of bath sink water delivery tube (copper inside, chrome plated) that is 5/16" ID - Cut them straight on the ends and don't crush them because the dowel pins must slide through them.
The 3/8" springs may need to be "unwound" a tad to open them up to slide over the spacers. 7/16" ID X 1-1/2" long springs might be a better choice.
That's it! Order everything from Amazon and it'll be delivered within a week.
Good Luck! Gordon
