ok thanks....yah i look down at it throught the engine compartment and had my step brother spin the axle and from what i see throught the hole in the case theres still one pinion with that shaft holding it in still there...also i noticed that the shaft that holds the pinions in on one end its sticking out farther than it should...

Oh! Sounds like he blew a pinion pin!!



If its anything like this. Drop the pan and inspect for shavings and open up the filter too.

It might look something like this...
