[urq] NAC : CV joint rebuilt...

[laraa at sympatico.ca]

Good idea indeed. Only problem is the joint is alone of its type on this
car. It's the rearmost joint of the propeller shaft, and I doubt dismantling
a CV shaft for any wheel will get me the answer I'm expecting... 

Thanks anyway, Keith.

I have no knowledge or experience of Saabs but my guess is that allthe CV
joints on the car will be similarly marked (one would hope so) So could you
perhaps open up another one but this time note the arrangement and photo it?
Just a thought if you get properly stuck.
