IFS Front axles/CV's

Are the front axles/cv's the same across all the IFS models or are there diiferent versions? I'm wondering are there different lengths and do the cv's vary in operating angle?

To answer your question there are different lengths and diameters available but generally the maximum working angle of a CV is around 29 degrees.
Porsche 936 CV's can operate on up to a 45 degree angle and thats why these are used in the long travel IFS systems for desert racing but they are big $$$

Within Pajeros, the earlier 2.6 models had smaller CVs which were easier to break than the larger CVs which came with the 3.0V6. Someone who used to break the 2.6 CVs regularly hasn't had problems with the 3.0 CVs - which isn't to say they're indestructible.
I was looking at my front end recently, and for all the lift I've got (almost touching standard bump stops) the angle is still pretty mild. Nowhere near 29 degrees.
I also once read that some Yamaha ATVs use CVs which are very similar to Pajero CVs, and they run at significantly greater angles. We won't talk about torque figures...
Cheers,

Thanks, I'm trying to see if there is a Pajero option that will be better to use in a Vitara. I know that Hilux IFS shafts can be adapted but am looking at all options. Porsche 930 CV's can be picked up for around US$50 but adapting them will cost.

Even within V6 CV's there are differences, in the GenI anyways. I swapped my old manual trans CV's into my auto-equipped rig, since they were bigger on the round than the auto axles were...

Interesting.
Does your auto rig have a low pinion diff or high pinion? Looking at the Tech thread, the Gen 1 V6 had 8" low pinion, but the 3.0 Autos in the Gen 2 had 7.25" high pinion diffs. Maybe your auto scored a 7.25" high pinion and the smaller CVs went with the smaller diff?

Nope the diffs were the same, and the splines that went into the diff were the same, but the actual circumference of the shaft was bigger on the manual CV. Given that the splined ends were identical, maybe there's no benefit to the manual axles, but I had them out for rebooting anyways, and usually bigger is better, right?

So my GF tells me.
