X11 08 - Problems!

[samd]

Just purchased a x11 08 - Just got a few problems - First the front upper wishbone still has forward/backward movement with all the kit washers on ,7, looks like in needs 2 or 3 more. The head of the countersunk ball joint screw on the steering catches on the edge of the chassis as the steering turns, and finally the rear propshaft bearing, when the rear gearbox top is fully clamped down, still as apox 1/4mm movement up and down - I had this same problem on my xrs, which came second hand so i put it down to wear. I have checked without propshaft in, bearing is moving up and down. Everything is clean from burrs and clamped down fully. Anyone else had this problem??
Any other tips...
