So I've never owned a 4wd nor a truck for that matter. I bought an 87 F150 today but it needs some work. I just have one question where can I need a bushing to fit the end of this arm but I can't seem to find one. Can somebody drop a link or tell me where I could get one?

 

I think you are looking for a radius arm bushing, see link at Rockauto http://www.rockauto.com/catalog/raframecatalog.php

 

A local auto parts store should have them, if they do not They can order them. Replace both and get the poly bushings not rubber.

 

Those are very hard to change. Good luck
