We opened up the bearing bores on all the new Grippers and Sliders so you can practically put bearings in with your fingers now. Go in easy, come out easy and spin for days.
To answer the question just prop the wheel up on both sides so the bearing can fall out and stick something through the other bearing like an allen key at an angle and hammer on it until it come out. Hammering it in a circle so it comes out evenly usually helps too. Also when you put new bearings in it is good to lube the inside of the wheel so they slide in and out easier.
