What type of removal tool do you use to press out the rear ball joint on e60 e65 etc? I understand there a bmw tool for this. I actually use the OTC ball joint tool that works fine. I have heard people using generic ball joint tools etc. But for the diy'r that will maybe use this tool once. It really doesn't make since to buy. If you're going to spend 300 on tool. You might as well take it to shop and have it done. So what do you use. How about the harbor freight 63725? Has anyone used it? Or maybe something else out there to help the diy'r.
