ok...after many weeks of delays i finally have this assembly apart
when i rotate the old hub, i dont hear anything unusual (no rubbing or grinding sound). when i went to take it apart there was a lot of purple oil in front of the stake nut (magic purple)

the old one feels a bit grittier than the one i got from roverland, but then again mine has 150K on it.

so do i replace whole hub or is this just the o-ring. seems like a lot of fluid to leak for just an o-ring when i have not driven it. i am happy to get a $200 credit with roverland for other stuff but dont want to cheap out and ruin brake pads, ets... i am really looking for final confirmation to trash the old one.

there seems to be a ton of old grease built up where shown in attached picture (between flange and bearing) does that mean it is in fact a bad hub?

thanks for your advice

That is a tough call, do you replace a $.98 o-ring and risk the hub beinig bad and having to do it all over again or just do it all and be done with it?
I dont know.
I am cheap, I would replace the o-ring and wait and see.

 

thanks spike.
well i got to the task before reading your advice.
i decided to go for it and put the new one in.
reassembly was a snap.
