like 'cheesy steel' might have been right .... or maybe a roller
failure chewing it up. All other ends look fine, greased OK, indeed
this one looked well lubed, it was just dug away ... ;)

Castrol LM .. dunno about the Moly. Any recommendations?

Yup.

You're right, the only vibration occurred when the UJ had already
failed, the prop is absolutely fine. Just tried it out after replacing
UJ's and all is well again at any speed or condition.

Stays compressed.

Loads, about an inch, maybe inch and a half, maybe a bit more.

Heheheh, I'd tend to agree with that ... ;)
