Hello Jaffa J and ODK members,

Well that's an interesting and significant question.
I wonder if this problem is due to a previous over-torquing?
I mean, more people nowadays using 'rattle guns'....
What's your opinion, given your experience and that it has been 'bugging' you.

There are legal issues in giving advice on critical components.
I will need to default to our engineer and Moderator Grumpy on this.
He will have an answer, I'm sure.

In the meantime (if it helps) Click HERE for some elevator music. smile

All very interesting.
