your truck should not be that horribly off..... your tire wearing on the inside may also indicate a bad alignment. also may wanna check all your suspension components make sure nothin's bent or loose.

ball joint play should be very minimal. you can check it with the truck on the ground. grab the top of the tire and shake it towards and away from you. you will notice if it has excessive play if it moves in and out too far.

 

I shall go check again...
