I've seen several tech articles including clarks garage, but have not seen any reference to this, although I thought I've heard of people doing this. Several of my current CV joint bolts are loose right now.
And what type of loctite?
thanks

It is good idea to use blue on new bolts and not to used old bolts at all.
Make sure you thoughly clean the threads and the holes to ensure there is no grease there.
Tighten to 30 ftlbs.
I had a set of bolts back out after installed new bolts and used loctite, but did not full clean the threads. Believe me it sucks to have the bolts back out on you on the road.

Yep,
I was stuck on the AZ freeway in the middle of summer in the afternoon rush hour.![Mad](https://rennlist.com/forums/images/smilies/mad.gif)
Luckily I was able to get home with a friend and go back to the car an install some old bolts for the ride home.
While the half shaft was faling about it took out the speedo sender on the tranny and ended up jambed between the exaust pipe and the tranny.
Not a fun experinece.

Loctite Blue is threadlocker #242 - depending on how.where you buy it, it's not always in a blue tube. The threadlocker not only helps ensure a good lasting fit, but also prevents rust and corrosion so the next time you're in there it's not so painful to remove.
Also, Loctite has just released new versions of their popular threadlockers and anti-sieze that are "sticks". I find them a little easier to use on bolts, etc. The new medium threadlocker stick equivalent to #242 is #248. for high strength semi-permanent bonding, use Loctite Red threadlocker #262 or stick #268.
FWIW, I use the threadlocker #242/248 on the Koni insert rebuilds and conversions as well... just as an extra measure of safety as they are already lock-washered.

Another thing to remember is that everything is clean when you use loctite. If there is any grease / oil, it won't work.

I always clean the threads with brake cleaner & cotton swabs until they're BONE DRY. Stuff a paper towel behind the flange when spraying so it doesn't shoot into the trans or wheel bearing seals. I've done this on 4 different axles, and they're always tight when I check them before a DE event. I don't use Loctite, but it's not a bad idea. It just makes it harder to clean up the threads next time.

i just finished my passenger side CV joints today - cleaned and repacked. for some stupid reason i bought enough new bolts to use 5 on each joint, and use 1 old bolt per joint. on the final round of tightening everything, the old bolt on the outboard joint snapped. i had to completely remove the axle to remove the remaining fragment. added another hour to my job. from now on - use ONLY brand new CV bolts

I think I recall reading in either an old thread or Pano that the bolts are torque to yeild, so you actually really, really should not reuse them as Joseph found out.
The pinhead who worked on my old Scirocco didn't tighten the bolts properly when he replaced my CVs and the bolts backed out on the driver side inner CV. It all came loose at a traffic light. Got on the gas and the revs went through the roof but no motion. Pouring rain and near freezing. Not fun.

I personally would not use Loctite blue on the CV bolts.
Anyone that has removed those "Damn#ioi$ky" cheese head bolts know how easy it is to strip the bolts.
Remembering this, now think how it would be to remove the cheesy bolts WITH locktite on them!
Just use new factory bolts and the next time you remove them, you will thank me.
For anyone that is removing and reinstalling the CV's with any frequency (couldn't imagine why) I would recommend installing safety wires.
Again....no locktite.

Last winter I did a clutch job. I did just about everything you're NOT supposed to do when I put the CV joints back on. I reused the bolts, didn't use locktite, didn't even clean the threads all that particularly well. I've put anywhere between 2500 and 5000 miles on them, and just checked them a week or two ago. All of them are still tight as spec calls for. Of course, at the time I didn't know, and I really wouldn't recommend doing it, I just got lucky.
Anyone know if the 12 pointed bolts offer any engineering benefit, or were they just invented solely to **** mechanics off?
