Rober, a good practice to have when any wheels are changed or removed for any reason is to nip the rear left wheel again once you get home or after a drive, I really believe this has to do with having such a good rear diff in them, is your left hand drive or right hand drive, I think the right hand drive patrols have the issue with the rear left wheel & vice-versa, I am extremely weary of it now after it happened to me, I check it periodically & before any major trip, never been an issue since
