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

 

If the U-joint broke, then it wouldn't be connected.
