How did they break? if you use the plastic balls they fail quite quickly and the hinge pin can then damage the hanger.
I always ran plastic - but if I had the money I'd have liked a couple of alloy hangers on there.

Yes that's the diff joint you need - don't be tempted by any 3rd party nonsense, get the real Tamiya diff halves.
