I was out last nite riding and in some sand with 4wd engaged. I heard a pop and all of sudden the right front wheel quit spinned. Now i can grab the front drive shaft from the transfer case to the wheel and wiggle it back and forth and move it in and out. Is is it the U-joint gone?? and if so how to get it apart?? thanks

 

I looked at it again today and it seems as tho there is only play in the bottom of the drive shaft right behind the wheel nothing is loose at the transfer case
