1.Make sure the both sides on Z axis are staying at a same height:

6.Check if there are some flaws(bad threads or bent rods on Z axis).
7.Spread some lubricating oil on rods of Z axis to see if there is a difference.
8.Check if the hole on the top plate is too small,which leads to the blocking issue(remove the plate to take a look):
