What the hell is in my axle housing!!!!

[oilhorsejack]

If you disassembled the birfield itself, there is a "cage" that hold the large roller balls inside the bell of the birfield.

If you disassembled that...assembly.... It CAN be reassembled backwards, thus having the "cage" in backwards and causing an interference.

Either way, the birfield/axle assembly is either not seated in the differential far enough or it's not assembled correctly because that's what's stopping your spindle from installing.

Ok thanks!
