Idler arm failure

Is it a 67 year model?

If its a 68 or newer there used to be a rebuild kit you could get for it that replaces the internals with a pair of ball bearing races, metal spacers, and a grease fitting. I bought 2 ,of these kits on ebay a couple of years ago. They can be removed, and installed in a different idler arm when the other end wears out.

I believe these were old moog service repair kits for idler arms. It doesnt fit the 67 only idler arm tho.

Hope that works for you.
