I know there is play in the lead screws side to side for assembly but not up and down is this normal?
Or is my lead screw nut worn I have a new lead coming just wondering about the nut.

Something seriously amiss there - normally you would expect 1/10mm or so. It could well be that the setscrews in the coupling sleeve between stepper and leadscrew are loose - certainly worth checking. I they are loose, make sure that the weight of the Z assembly is not taken by the stepper bearings - they are not designed to support too much weight. The motor specification suggests a maximum of 10N (approx 1Kg) axial force.
Also check the nut itself is not loose - if it had worn to such an extent as to give the play you see there would be plenty of physical evidence on the leadscrew.

There is no problem, however simple, that cannot be made more complicated by thinking about it.
