    It's a pain to fix.  The most likely cause is the two screws that hold the bar to the extruder bracket are loose.  You have to slide the whole gantry up off the machine to get to the screws.



      I ended up drilling a hole in the left upright so I could at least get to one of them.  I still have to remove the entire Xbeam/gantry assembly if the left screw comes loose.  Now with the gantry off I can tighten the left screw, put the thing back together, square up the X beam to the Z upright, tighten the right screw through that hole I drilled, and then deal with the adjustment on the right side bracket.  (The screws are accessible on the right.)

    Here is the 6.35mm hole I drilled.  With the gantry positioned correctly that right side screw head is in front of the hole and I can get an allen wrench to it from the backside.

    PITA.  I'm sure there are videos on repairing this and re-calibrating the X beam/gantry.  CHEP probably has done one and he's good with the Creality machines.
