I have a 1997 753. On the end of the ram where the bushing is pressed in, is there supposed to be a grease zert. Mine has a hole where it looks like one was there but theres not one. I bought a new bushing and it dosnt have a hole or any way to get grease to it. So I guess my question is should I install the new bushing and drill a small hole in it. Then insert a grease zert?
