I’m pretty sure that is what I used..a “punch” with a flat end, not tapered, not pointed. If I’m misunderstanding, I’d need to see a picture of what you mean. Having said that, I like tangofox007’s socket idea, might try that when I do the other side. (Even though the noise is gone, I’m putting new rotors on in front anyway-if I wasn’t I might just leave the right side bearing alone for now, but for the relatively low cost of a bearing, I figure as long as it’s apart I might as well have new bearings on both sides).
