Wheel problem GMax FS9

I have buit a Cessna 150 to be used as AI but am having a problem with all wheels flopping around and not spinning on the X Axis.
I have un-linked all parts several times, put the dummy objects in several times at 0,0,0, checked and rechecked the pivot points of the wheels to no avail.
Any advise as to what I should be looking at would be greatly appreciated
