Good morning-hope everybody had a good weekend.

It would seem as if one of the rights of 914 ownership passages is dealing with self-loosening axle bolts.

Will the correct size spring washers from Ace deal with this, or do I need special serrated ones, or do I need to safety wire them?

Thanks in advance for the help, have a good morning.

New Schnoor washers and proper torque will keep them right. Threads need to be clean

Yes the new Schnoor washers and clean threads, but adding safety wire does not hurt either.

I do that, and then safety wire them. That works every time. You do that when you are younger and drive the 914 to clients. The CV fell off on my way to one of them, no problem, except hand got covered in CV grease, luckily I knew them well, not a first impression sort of thing. Still not my most professional day.

Same day I also discovered my fuel level sender was not working and ran out of fuel on the way back home. Murphy was batting a 1000 that day. Still had a huge smile on my face from (IMG:style_emoticons/default/driving.gif)

That's not a factory bolt or washer.

Those bolts are not the original type of bolt used for 914 CV joints.

I would be ordering some new bolts and probably get the "drilled for safety wire" bolts since I was getting new bolts.

You need to be sure the bolts are the correct strength.

It’s the wrong bolt for the CV joints. They are supposed to be the riebe style, which looks somewhat like an internal multi faceted Allen bolt. As already stated, you also need the special schnorr (spelling?) style of lock washers for the bolts.

Flattened, likely from banging against the loose CV.

Factory bolts /4 are only threaded part way, 8mm tri-square female. schnorr washers are thin wavy washers with teeth ridges.

Rebuilding my CV joints and noticed my car was missing one roll pin and had no schorr washers ! Replacing all the bolts, adding the washers. Amazed the car did not have any issues running just on roll pin on one of the joints. I guess low power application helps !
What is the torque spec for the CV bolts?

The Schnoor washers are a one and done part, which is why we get in trouble in the early years of 914 ownership.

"Ya mean I have to get new ones every time I pull the engine?", yes.
