- Hey Fabricators,
In this video I do a comparison between a 930 plunging and a 930 non plunging CV joint.
Both of these were purchased from RCV Performance Axles.
The non plunging retails for %229.99 and is SI15RF-30
The plunging is $399.99 and is SI15VL-30M - ยานยนต์และพาหนะ
Very interesting. Understand the need and new there were both available but did not know how it was accomplished. Thanks for sharing.
You're welcome. 👍
Very well explained now I know which way to go 👏
Very informative Doug, thanks. I wasn’t aware of these differences.
You're welcome, thanks for the comment. ✌
G'day,
Excellent video.
It will be interesting to see them applied to the car.
So thanks for sharing ✌️ Peace from Melbourne Australia.
Hello Kevin!
Good to hear from ya.
Peace from US. ✌😁
Great video. A couple points on the joints from the past: The German VW/Porsche Lobro mfg Rzeppa joints ball cages are extremely hard and are subject to braking apart and into small pieces that can mean a DNF. For short life racing applications of extreme angularity use such as off road racing, we used to anneal the cages to drop the hardness down. When the hard ones broke, they would more or less shatter. Annealing avoids the busting apart and extend the life of non-plunging style joint's in racing applications.
For the non-plunging types, one might consider using custom axles with extended spline lengths vs factory fixed length. They are made for a loose fit for the inner hub. These have no inside bottoming shoulder and they allow the ring of balls to rotate in their own natural plane of orbit. The axles were also smaller diameter torsional axles that were able to absorb lots of hammering and extend the life of transaxle used. Sway-Away still makes these axles to your specs out of 300M or E4340 for various applications I believe. They were rolled splines and fully centerless ground if I recall correctly. The old stock Type I VW IRS transaxle drive flanges had a minor diameter inside the flange seal that was smaller than the OE axle diameter thus making a stress riser and would handily brake the drive flange right off the stub shaft.
Excellent information, thanks for putting it here for other people to see.
Thanks for that, my only exposure to them was the plunging style.
You're welcome!
Greetings Mike, If I'm not mistaken, If you are using a solid axle, you use both kind. The inner use the Plunging CV and the outer ( near the spindle) use the Non-Plunging because of the amount of angle of the spindle as you steer the veh. lock to lock. If you noticed also that the ball separator is protruding to one side more than the other on the non-plunging. If I'm not mistaken, the protruding part will face toward the tire. If installed away from the tire , the separator will cut a groove on the axle. I see that you have those painful crack by your thumb nail that I use to get when I was wrenching. I used to Super glue it cause non of the band-aid work. It's been awhile, I was away from the comment section do to health issue.
That crack on my thumb won't go away and it's amazing how painful it is. I might give the super glue a try. The band aid helps, but not really that much.
I think I've decided to go with the plunging on the transaxle side, because there is a little bit of plunge needed. I agree with what you said above.
Thanks for the tips. 👍
Thanks Bud for The technical details.
See you
:))
Hey Valy! Thanks.
I've never heard of the non plunging type before. Very familiar with Type 2 style units though.
Well you've heard of non plunging now. 😁
Please @Doug Bug, did you know the splines type and module of type 930 with 28 spline ? Thank's you
Can u run the non plung on the trans side and a plunging on the trailing arm side?
You can, but you'll still be limited by the angle of the plunging CV.
Long time how are you? Plunging is famous for cracking the cage under full power suspension angle load. Ask me how I know. P3 vs non p 0.
I'm well thanks, it's been a while.
Good to know on the plunging, and it does seem like that would be when they're most vulnerable.
