I'm not sure you can have different amounts of backlash in the same axis.

Backlash is caused by space between screw and nut / gears / belt and pulley. The space results in a deadzone where when the motor direction reverses there is a time when the motor is rotating without the axis actually moving. Then the motor has rotated far enough and the space / deadzone has been taken up and the axis moves.

You could also be dealing with stick slip
