I have determined that it must be the reel table and not the shaft. this is because the plastic reels seem to move back and forth. if the shaft were bent, they would just not be paralell to the face, but they would rotate evenly. it must be the table, because the rotation is not even. the right side is messed up pretty bad too; the tape bangs up on the reel. but it does not seem to affect the right tension arm. this is probably because of the direction of flow of the tape. so about this "easy" fix??? also, fast forward works again (with the smaller reels). not sure what that's about. I think whatever is driving the right side might be weak?
