I would like to change it, thanks to everyone
If you're talking about the dogbone, which is the diagonal piece that attaches the lower track to the upper track, allowing it to travel up and down, but not side to side.
There are rubber bushings that can be replaced to restore the rigidity of the dogbone, you don't replace the dogbone itself.
American Carrier Equipment has the dogbone rebuild kit.
