Outer Limits 4x4 Board

have just gone through and greased all the nipples on the paj. when i did the passenger front upper balljoint, it seamed that the upper arm moved upwards as the grease was going into the balljoint!! i take it this means its nakered?
what other checks can you do to see if it is worn? doesnt seam to be any undu noises or looseness at the steering wheel.

To get play you need to jack under the lower arm to raise the top arm off the bump stops. Then grab the wheel top and bottom and lift/wobble
