another screeching halt...
looks like i'm off the road for a few days again. i've got the wrong seal.
FRC8220 is not the right seal for my rear diff.
after destroying/removing that metal thing and discovering that it is in fact the oil seal i then quickly realised that my new 8220 seal is wayyyy too small.
