Defender axle number identification

Is there a way to identify a Defender axle to know I'd it is one of the ones with potential issues with weaknesses that could cause a failure.

I have purchased an axle case that I was told was from a 300tdi, but the axle number is stamped in dots. Is it possible to identify it from the number? It would be good to check this before I swap the axle case on my vehicle for this one.

Thanks for any help you can give.
