try 8mm x1.25, believe that what I've used in the past. Hit them with penetrating oil and go easy and even so they don't break. i usually just get a hammer and hit either between the studs with lugnuts on to protect the threads or the outside front edge away from the lugs. hope this help hopeful I'm right about the size and pitch of bolt.Anyone know the spec size of the empty bolt holes on the rear drum used for removal? See pic. 2004 X.
Thanks.
