The easiest way is to clear the HAS_JOURNAL flag on the filesystem
with debugfs.  Once you do that, e2fsck will detect that the journal
record is inconsistent and will fix everything up for you.  tune2fs is
then able to make you a journal.  

However, tune2fs will still create a journal file if the filesystem is
mounted, so if this is the root filesystem you are talking about, you
will still end up with "/.journal" present.  tune2fs can only create a
completely hidden inode if the filesystem is unmounted at the time.
