You probably mean the special socket required to remove the bearing adjuster and lock nuts? If so, you could take them off/reinstall using a punch, but doing that will risk not only damaging the nuts, but also will not allow for proper torquing of the lock nut. No real reason not to use the proper tool, GM trucks still use the same lock/adjusting nuts on full float rearends, the socket is readily avaialbe at any parts store or tool dealer.
