Interesting read and makes sense, although I question how many apart from extreme 4wd peeps or a very severe incline that possibly shouldn be attempted that would be in a position to flip there vehicle backwards from a rear locker only, but then I guess it's possible.
Fair enough but it's a good read none the less and it gives some insight to how diff locks operate in different situations for those learning how diff locks work.
this is only a comment made by some random guy that I thought was interesting
and wanted to share it with all of you guys no need to take this as gospel or anything lol
