sleeves were removed. They came out mostly intact. These bushings will need "messaging" with a sander in order to even get them to start into the hole. 33.5mm bush into a 32.4mm hole. I'm sending all the sleeved Whiteline bushings that I was going to put in the knuckles back to CZP. The thought of going through the sleeve removal process on the aluminum knuckles and maybe having to message the bushing to make it fit, makes me want to stay stock for a little while longer. Would be nice to hear from someone that has made these sleeved bushings work.
