So I had a seriously stuck bearing on my R2. I looked up everything I could to remove it. I finally tried something that absolutely will not hurt the bearing or deform it. I used a 1/4 inch drill bit, but not the cutting end, the chuck end. Just slide the bit into the inside of the bearing and wiggle it back and forth. It works like a charm. This won’t, of course, work if the bearing is stuck on the axle side. I suspect you could unscrew the axle in that case, and then use this technique. This is probably nothing new to many of you, but it’s new to me. Hope it helps.
