Re: zf5 pilot bearing?
Definitely going to have to remove the clutch and disk. I couldn't tell you if you need a puller (I've never just replaced the bearing). It may need to be pressed out and new one in, but it's only a few more bolts to pull the flywheel off at that point. Make sure that you check the throwout bearing and maybe even check the release lever for wear while you're in there (those parts aren't that expensive). Cheers!
