Ya u pretty much need the puller, i've tried in a pinch w/o the puller and it was a mess. I'd lend ya mine but im in sask, and all i'd charge is a mcdink's meal, Maybe a local dealer will let u borrow there's or just order it in from a suzuki dealer for a little over 200.
Now only if there was a place to rent specialty tools for toys,just like crap tire or partsource does, with better service than them ppls.
