yes they will unlock in reverse in the auto position...that's how they were designed 2 work, but getting out and locking them in with the Tyre iron is no different 2 getting out and locking in manuals, if your doing any sort of extreme work they should be locked in manually. Under stress everything will fail eventually, still have yet 2 see real proof that manual hubs are better than auto's.......and yes my auto mechanism has been taken out recently, but like the rest of my 4b, they were abused and abused
