The ones that hold the dog bones on mine are bushes just the one that holds the knuckle to the frame are roller , and easier to get a kit from Wemoto I would have thought well that's what I have just ordered so hope that's the way don't think they would work out any cheaper at bearing shops , by what every one on hear says its the one on the bottom of the shock that is the hard one to get ,have stripped mine in readiness and was surprised how easy it was .
