Somehow it seems a bolt sheared off connecting the axle. Apparently this can happen if bolts get loose and one by one loosen until one is left and breaks off. Now my question is, has anyone gotten a bolt out?
The bolts seem to be made out of very hardened metal. Attempting to use drill and use a bolt extractor barely even makes a dent.
If this has happened to you, how did the broken-off piece get out? Searched and found just one other person that had this problem. Thanks!
