The clip is broken that holds the spider gear in the diff. to the axle. It would be a good idea to remover the diff. cover and diff. assembly to remove the pieces so they do not end up between the gears and causing more damage.
Actually it's easier if we tell him the end with the longer splines is the axle end.
Yes there is found that out.Zach..one thing I forgot to metnion. Make sure you put the correct end back in the trans first. There is a difference.
