I have a 20 ton press. Do you know where I could buy a kit? I'm not worried about the luxury ride it's a focus. [histerical]For stock bushings, replacement arms are the only answer I know of.
Aftermarket poly bushings are a major project to install, and are used only when you want a performance suspension that's much stiffer & not as smooth/quiet.
There are some good old threads with pictures & details on installation of that type, having a press to use is the only way to do it properly & easily.
