After my experience I did the same procedure with no surprises thus far. Still keep 6 extras onboard just in case though.

Subject: Re: CV bolts and DPO mechanics
After sitting at an exit in Las Vegas Waiting for a tow truck
Thinking my Syncro Trans was shot
Only to find that a CV Axle had dropped on one side,
(onto the drive shaft frame where I couldn't see it )
I found that the One thing that is more important than torque is to
Keep the CV Grease Off of the bolt Threads !!!
It's a pain to do, but oh so important!!!
After inserting all of the bolts
And just before I lift the axle into position
I start wiping the grease off.
At the end of this process,
I wipe them with denatured alcohol.
and then I use a releasable lock-tite on them.
Then torque them down.
That grease is just so slippery
I don't care how tight the bolts are
chances are their going to come loose eventually!
Of course, After the job is done and the tools are put away
I treat myself with a little "natured" alcohol !!
But,,, that just seems to make me "more" slippery !!! heh... heh... ;o)
best,
