What needs replacing??

[Nard Cox]

Hi guys,

I bought myself a RCM Slipperential via eBay (turned out it was from Bryan here). Now I got it but there is a big wobble in the output yokes (Bryan mentioned this in his ad). So I was just curious what I should replace:

I put together a small movie for you to check the play:

I'm guessing it are the two end cap plates that are worn out? I've read Mike made some hardend steel versions that should ''last forever''?

Thanks guys!

EDIT: Any other hints on what would need replacement while rebuilding, some gaskets and o-rings?
