CV Bolts worked their way out???
15 months ago, I changed a CV joint (outer pass side). I am absolutely POSITIVE I torqued the bolts to the spec in the Haynes manual. Today, I was poking around under the car (boring lunch hour) and saw that two bolts seem to have loosened all the way out - the only thing holding them there is the CV boot ridge.
So, my question is... Is this common? Was I supposed to use some form of thread-lock? What gives?
TIA,
Dale.

Yes it can happen especially if some of the grease got into the threads while you were putting the bolts back in. That's why I recommend going back in and checking them after a couple thousand miles. I check mine before every autox.

Thanks everyone for your insights. New bolts came with my kit, but I do know some moly made its way into the holes while I was packing.
Anyway, when I got it up to tighten them - two were completely out (as I stated above), two were loose enough to turn with my fingers, and two were still tight.
Scary. I'll never go more than a month without torquing them again!
Thanks again.

Nixwiz - it's hard to notice anything on top of the regular noise and vibration! But really, no - I had no clue until I peeked underneath for a different purpose (trying to see how much of my exhaust I could remove).
