  1. Front Differential Fill Plug Stuck

    4x4 Drivetrain
    The front differential fill plug on my 2002 Trailblazer is stuck. This is the oversize plug. I used a 24" breaker bar with lots of force but it does not budge. I'm afraid any more force with shear the threaded shank of the plug. Does anyone have any suggestions on how to remove it?
