stock 96 xj vibration at speed

Hey folks.
I have a stock 96 xj country that vibrates (not in the sterring wheel) when I drive over 60 mph.
I just bought the xj a week ago (it's my 2nd one). So I'm going over the drivetain in the garage with the jeep in park
and the command trac in 2H and notice that there is a little rotational play in the front drive shaft from the transfer case to the diff.
But there is no play in the rear drive shaft at all.
Is this normal?
Could this contribute to my vibration?
If it's not normal, could some one please advise me as what to look for?
Thanks in advance.


BTW, great site guys.
