The VW CV joints have about 1" of plunge, but I made custom axles to slide in and out of them.
And when assembled every thing is captured and can't come apart.

SARgo1,  you may want to consider over engineering it for the added weight of the gear you plan on having onboard and the added weight of the suspension.  Also it will help in the future when you decide you want some more HP, say 50 or so.  Easier to do it now rather than later.

Bingo, ascaw. you hit it right on the head. Over engineer it, you don't want to work on it all the time.
For a good independent suspension you have to have floating outer axles for the wheels to move
straight up and down through the travel of the wheels.
If you use u-joints you end up with the suspension of a VW swing axle.
The tires will fold up under you when you catch air or in a turn.
You also end up riding on the sides of your tires.
If you have to change a u-joint you'll have to take every thing apart to change one.
I have never had to change a CV joint in 10 yrs on any of our Springers.
That is why I use CV joints, but if I did have to change one this is how it is done.



Ah yes, you're right. I forgot about effective axle length change with suspension travel.

I've never had a VW cv joint in my hand. I'm assuming it uses some type of "plunging spline shaft" to account for axle length during articulation?

I know most vehicles just use and inner tripod joint to account for suspension action, but it doesn't look like this is how the VW units work.

I'm not looking to race the thing, just smooth out the ride and possibly get the outer hubs further away from the tub (and maybe tweek axle center spacing) to increase my tire options.

I do have a tendency to not be able to leave anything alone, building for more HP in the future might not be such a bad thing......;)

years ago i was looking at P.T.O. shafts and joints with their type of yokes to do the job. BUT  whistling

yea you are right , if you have stock gearing and engines then all you really need is about 3 inches of travel at the most. you just want to smooth out the ride. iagree

ya know, it occurred to me that being a non steering axle, you don't really need a CV joint for a springer build.

Also, since it's all relatively low power (sub 30 hp engine, although skid steer is going to put some stress on it), it doesn't need to be overly robust.

I'm toying with the idea of using universal joints instead of the VW CV joint.

They can be had much less expensive and if you use a common one, can be sourced at nearly any parts store right off the shelf.

And since they are sealed (and grease-able) they wouldn't need boots like a CV, which can be vulnerable to tears/splits.

It's relatively low travel we're taking about (2-4" I'm estimating) so it's well within the operating range of a U-joint.

The only question would be the yokes, which I would probably end up making. Seems I could make the stub shafts with a yoke end, a center axle with yokes and then it would be a matter of figuring out a bearing yoke arrangement at the wheel end. The older 4x4 trucks used this arrangement at the wheel, although on a larger scale. Decent enough to use as a design concept though.


Any opinions (good or bad) on that idea?

from what Whipper told me all the stuff he took off and then all the stuff he added was only about 200 lbs more that the stock weight. I was surprised also after floating mine.

They are 3/16 thick cold roll plate.

Jeez, I that must weight a couple pounds!

Im surprised it floats as high as it does on some of the swimming vids you've posted on youtube.

hey Whipper weren't the ones on the front of GOLIATH from a kawasaki sidexside and the rears are 200 lb coils on a rhino rear shock.
but you get the point SARgo1. they have to be short enough and stout
No they were all front shocks remember we had to buy after market heavier springs for the front.
I don,t think alum side plates will work, they would have or be twice as thick and a lot harder to work. With. Watch some of the under car videos and you can see the side plate flex.

Whipper

May I ask how thick your plates are if they are steel?
