So I was rebuilding my CVs and I notice the spider gear are different and thus it gives the CV more movement on the sharper edge one (the CV on the left). So is it bad to have a mismatch set. Should one belong in the inboard and the other for the outboard ?? The one on the right have very limited movement. What does the 914 Gods say.....

We had found it was the cages I believe. The "Meyle" CV's hyper extended and the GNK Loebro brand did not. Mark had a failure while coming out of a driveway apron and powering on to a street. I think it (hyper extension CV) should go on the wheel side or... better yet, in the circular file cabinet.

There are several good threads on cv's here in various places if you haven't built any yet. To your question specifically...

There is no outboard and inboard cv. The bolt holes and roll pins line up on either end of the axle and, other than the camber on your wheel, there is no significant difference in the deflection angle between the inside and outside cv's. But here's a tip.

You can extend the life of your (good) cv's by putting the cleaned and repacked units on the other end of the axle from which they came. It makes a different wear pattern and the load is transferred to different parts of the races and the cage.

Get them cleaned up and look for excessive wear, which shows up as metal galling or really deep grooves, and usually pitted balls. As we all know, pitted balls are unacceptable. A note about axle rotation because you could just rotate the axle/cv unit and bolt it back up 180 degrees from how you found it and accomplish the same thing.

In general it's better to keep the axles rotating in the same direction because the metal-memory remembers shear-stress in that direction. I would also state categorically that anyone with a four cylinder car is unlikely to break an axle no matter what they do, but in a high horsepower machine it could become an issue.

Good luck!

Eric, " ... circular file cabinet" you mean store them away for later use, dont use that one ?

Thanks Eric

Circular file cabinet = trash can

Otherwise known as a "round file"

I currently have at least 8 CVs clean & ready for inspection then reuse on my current rebuild.

I was considering taking photos of all of them to post, but wasnt sure if anyone was interested enough to warrant the effort.

Should I post pics of good vs bad? I believe I only have one bad one, and the damage is near one end as pcar916 suggests above.

I really dont know how to tell a "use as is" vs a "I wouldnt use that", so I am also interested in this topic.

Pictures are always helpful. If not today, maybe tomorrow. Post 'em!

IMHO, the less extension the better.

Learned 2 things today. Thanks guys !!!!
