They come apart just like Profile's.. If it doesn't simply pull off: Take it off the bike (obviously?) and knock the non-drive side bolt with a mallet. This will push the axle and driver off. Then to get the driver off the axle, you just hold the driver, and knock the drive-side bolt, which pull push the axle off. Then you need to get the axle back in the hub..When you first knocked the axle out, the hub-bolt would've come out too. To get that back in you need to take all the pawls/springs out the driver*, then just use the driver and hammer to knock the bearing back in flush. (Will make sense when you actually do it) Once that bearing's in, the axle should be firmly in place. Now just give everything a clean, and lightly re-grease it, and put the pawls/springs back in. * Just make sure you remembered how they go back in!
