Check your CV joint bolts
Bolts had loosened on one my CV's - re-torqued.
Just thought I would post as a friendly reminder as these bolts are known to loosen apparently. Thinking of drilling and wiring mine for extra safety.

Yep, they loosing sometimes. I found this out years ago on a farm road far from home. Got off the highway and the first railroad crossing resulted in a sudden loss of power. Oh oh! Now what!?! Coast to the side of the road and check the engine bay. Nothing funny there. Revs OK. Sounds OK. Looked under the car to find a dangling half-axle with twisted bolts!
Luckily I had traveled that road before and was aware of a gas station about .5 miles down the road. Got towed there and had to instruct the resident wrench what to do…guess he was use to pick’em up trucks  But they were very nice about everything. I was lucky.Now I check them frequently and am considering drilling and wiring the bolts. |

I replaced the bolts on my '75 a couple days ago because the old ones were getting stripped.
I'd never done a 4-bolt CV with the M10 bolts before...boy, do those things take a lot of torque! 61lb! I thought I was going to break the things, but they held. Thanks for the reminder

Can thin lock washers be used to keep them from loosening and spinning out?

Remember Skinnerd's post a while back?
Seems as if it's not a good thing to have a loose shaft banging around your new SSIs. I'm going to check mine when I get home. |

re safety wires -- I'm still concerned about drilling holes in the heads -- they aren't that big, and tho some have disputed this on the basis of hole size, I'd be worried aobut stress cracks propagating.
Note that lubing the threads can alter torques and hence how "tight" the bolts will be. |

LOL, I used Schnorr washes and Loctite. After I had used the Loctite I thought "Opps maybe that wasn't such a good idea
 ".

drilling the heads of the bolts wont weaken the bolt itself, dont worry about that. Just be sure to deburr the holes or even add a small chamfer so the wire wont get cut.
A .040 hole will be fine. Use .030 stainless wire. you are good to go at that point |
