Just wondering if the comment I heard today was true or not. I was told that if you pull both axles out of your rear end install one and turn it your rear end will no longer work until you re-align the gears. The reason for me asking. I pulled both axles to replace bearing and seals. When I installed each axle I spun it to be sure the rolled freely. Now that I am done I realize the output does not turn. I have no history on this rear end it was a spare so I have never used it.
