Thanks, guys (and Angela).

I like it all, although I lean more to the ballads than some of those uptempo Jersey bar-band numbers. But I've seen a lot of his shows and have never come away disappointed. He seems like a very genuine guy.

It's true. It's all relative. I worked for years in alleys, borrowed driveways and under a plastic canopy. Every step forward felt great.

I don't recall if there is a difference in flange size (which would be a change) or axles themselves - probably are changes. But if you researched it and found the point valid, and were willing to make the changes - you might reap benefits on your setup over the long run.

Just a random thought from the one of the few chicks who post in the tech forum.

The 930 CV joints are whoppers. See this set for sale by Josh @ Carrera6 Parts

So it appears if Jack were to use the 930 joints on the inboard side, he'd have to shorten his axle shafts? Also note that Jack's outer CVs are not replaceable since they are welded to the axle shaft. A better choice would be to switch to the 930 axles/CVs that are bolted on both ends.

The VW sandrail hotrodders like to use 934 CVs because of their strength and angularity tolerance. I suspect that since the dune buggies have so much suspension travel, these beefy CVs are a must?



So what did you end up doing Jack? Just replace the axles entirely? Just curious since the boot kits are cheap, but a CV kit is not. That's typically why complete reman axles are a better value.

But even the reman axles aren't giving us the best chance of survival/durability. You gotta use a quality grease, even on new axles, if you're going to track or race them. Factory grease just doesn't cut it. Need to use something good like Swepco, Redline, Neo, etc. Something with a lot of sticking power that doesn't turn to juice like the economy greases that manufacturers use.

That's an interesting idea. I wonder if the Turbo joints could be adapted to the 85-89 axles. The jury is still out on whether the more-common failure for me is the rubber boots (probably Chinese neoprene, or whatever), or if it's the cages and balls. When the joints themselves fail, it's not always easy to know if it's because the boots cracked and the grease was compromised or if it was the sharper angle that was the culprit.

For now, I'm putting in new axles. I've got a track day on Wednesday that I don't want to miss.

But the two I took out might get taken apart, inspected and re-booted.

Dave, your failure was with the boots? I'd hate to go to all the trouble of re-doing my hubs only to find out that I'm going to have the same problems. Any chance of getting some measurements of the 930 piece you keep as a spare? It would be interesting to see if it'd be possible to create a hybrid half-shaft.
