This PORC hd SYE was installed 9 years ago. Np231 2000 XJ

Put about 80k on it and it is vibrating like crazy. The output shaft has a bunch of play in it and looks like it's weeping fluid too.

I seem to not be able to find any insight to which bearing and seal it takes.

These have all been verified to work.

Seal
OD - 2.7540 in.
ID/Shaft - 1.8430 in.
Width - .5 in.
---- National 470331N, Single Seal, Double lip
---- National 3946, Double Seal, Double lip, most closely resembles original
---- SKF 18472, Flange, Single Seal, Double lip
---- National 714675, Flange, Single Seal, Double lip

Bearing
---- 6207 (35mmx72mmx17mm) Open


Found this and ordered the parts!

Good to know.

That same unit installed on my XJ about 2008 or 2009 have a leaking output seal which need to be replaced. The bearing though is still tight and noise free.
