You can jack up your jeep from under your axle one side at a time to a point where the tire can freely rotate. Then go and try to rock the tire back and forth and see if there is any give. When I say back and forth I mean one hand at the top of the tire and one at the bottom.
As far as the driveshaft, I'm not really sure. I want to say there's a standard size for stock front and stock rear driveshafts but I could be wrong.
