I've got a 93 Mazda MX3 that needs the driver's side cv shaft replaced. I replaced the one on the passenger side 4 or 5 years ago with no problems. I got everything disassembled, the strut out of the way, etc. I put a slide hammer with a 3 jaw attachment on there and hammered like crazy on it and it wouldn't budge. I mean I worked on it for hours, too. I don't remember there being any problems with the passenger side, but is there something that I'm missing? Some type of retainer? The new one just has an expandig circlip that would fit in a groove in the tranny but it looks like it would easily compress. Can somebody give me a couple tips? I don't want to take it to a shop, but I'm getting pretty frustrated with it.
