Best place to get U-joint Axles

[Carlriddle]

I did read some post on how people ended up spending twice the money because they had to buy 2 sets of drive shafts.

I guess I'll stick with Rockford if I have to get any parts.

DSRace, did you take a look at the links I posted? Are those the parts your talking about?

If so then The only part I'd have to fab myself is a flange to weld to the inner 930 CV joint and to weld a 1310 yoke to.
So far, I have only read about guys using late model Front 4x Toyota Driveshafts for axles and having them cut to size.
 
So Im thinking thats my best bet. From gear box outwards:
930 Inner joint with flange and welded 1310 Yoke
Toyota driveshaft cut to length
Dana 30 Axle stub from XJ/YJ
97 Cherokee XJ bearing hub

How does that sound?
 

Why would you run a 930 inner cv?  A good set of U-joint axles wont be cheaper than a cv setup.

Not the CV, just the joint that it bolts too. I think thats what its called.
From the gear box it has a 930 joint on it. The current setup has a geo outer CV with custom axles.
Its a Chinese Roketa which was built by Superkart. All Superkart did was add a FNR and put in a 35HP Briggs.
I want to make new Semi Trailing arms and relocate the engine and gear box. Then I can make the axle setup to work with the longer travel arms.

Or is it called the 930 Cup?

[Carlriddle]

Cup.  Gotcha

DS will have to give his thought on driveshafts in trailing arm cars, but I know plunging on those slip shafts is not good.  Keep the plunge down.

With TA's there is no way to prevent plunge but it can and should be controlled. I'm a fan of  arm suspension as most know due to the ability to design with zero axle plunge.

99-02 f150 4x4.  Contact Livewire on here for just the outter cv/stub or you can buy the whole axle locally and  pull off the parts you need.  BTW the inner joint is not a high angle joint.

Actually, 97-04. 05 and up are the same spline but have the Vaclock 4X locking hub built in.

If you need something a little stronger yet, Chevy 2500 4X front joints are 33 spline, same as a 934........

All you've likely read about were all the issues with plunging 930 cv's. Non plunge have none of those issues.

Can someone tell me the difference between plunging and non plunging cv's? What you talking about? What is a plunging CV?

[Carlriddle]

The reg cv's, vw, porsche, are plunging.  Meaning the cage and balls and move in and out of cv.  Non-plunge the cage and balls cant move side to side, so no plunge much like a U-joint.  Either you need 0 plunge of your rear suspension system or you gotta let it plunge usually with slip axles.   

[fabr]

Design the suspension with zero plunge and the splines will slip enough in the stars to allow for any suspension deflection that will occur. For most people plunging cv's are the best route unless looking for max angle. Plunging 930cv's will go to approx 28 degrees while non plunging 930's will go to approx 40 degrees AND run MUCH cooler while doing so.

The only way to get no plunge is to build the rear set up with A-arms. Trailing arms will need alot of plunge, semi trailing arms les plunge, A-arms least- no plunge.
Corresct?

[fabr]

Yes.

[Carlriddle]

Mulit link?  4,5,6?  I limited mine to about 35*.  Boots seem to be the issue over that.

[Hollywood]

Only problem with building rear a arms is building the spindles for the right axle bearing. A bit more complicated than just making trailing arms with a 3 bolt plate to fit a 3 bolt axle bearing.

[fabr]

I don't agree on that.Correctly designing ta's is not a simple thing either.A arms can use the same simple stubs as you describe. right Carl?

[Carlriddle]

I can't think of any wheel bearing that would care which suspension design u went with.  3 bolt like most fwd cars?  T-arms if built right are a set and forget. I would only build semi t-arms with outter heim so I could get camber and lessen plunge.  But A arms are easier. A top and H lower.

TA's are trying to twist, tire always trying to tip in on top.  But can be easier to mount out of way, can be abused a bit more(maybe) and are used on prodution cars to keep owners from screwing with them. 

But standard 930's, type 2 offroad, type 4's will be more than enough for what your wanting to do and TA's will prob be easier to retro back onto a TA's car.
