Well, then you might want to avoid doing it if you can’t do it without stripping it. It sounds like you’ve got a slightly bent axle, though, given what you’ve told me so far.
Both halves are a little wobbly, you’ve got a vibe, and it’s taken several hits. I imagine that axle has seen better days.
Of course, taking it out and giving it a roll will tell you right away, but not at the cost of stripping it unless you’ve got a replacement sitting there with you.
