1970 IRS bug with 3" lift. What drive axle?

[jhodgson]

I got my spring plates re-indexed at last. Thanks for the help.

Now all I need is to get some drive to those wheels.

The stock CV joints don't seem to quite cut it in terms of travel, so after reading many posts I got myself some type 2 conversion flanges for the transmission side and some type 2 CV joints and disassembled my stock axles.

When I went to put the works together, though, Lo and behold, the type 2 CV joints are a couple of mils too big to fit the stock bug axles. I wouldn't be able to get the circlip on. Son of a monkey.

Should I grab the conversion stub axles for the wheel end and just run a type 2 drive axle end to end? If so, any idea where I can find the right length type 2 axle? My stock IRS bug axles are 16 3/8 long.

Or should I order some new shafts and run type 2 joints inboard and type 1 at the wheel? Like these shafts here: https://www.pacificcustoms.com/ac525201.html

If I go that route, should it worry me that the axles don't have shoulders on them like my stock type 1 ones do?

Or do I need type 4 axles?

So confused. Thanks again in advance.

Source some 1984 or earlier Porsche 924/944 C.V. joints, driveshafts, & axle stubs and then get bus-to-bug conversion output flanges for the transmission.

Just out of curiosity, do you have any downward travel left in the suspension? It looks like it’s pretty topped out at the moment.

I already have the bug to bus conversion flanges.

This is the first I've heard of 924 in this context. They're 100mm cv joints like the bus ones, I'm guessing?

Why those rather than the bus or 930? Thanks!

The 924/944 are 100mm but supposedly are able to withstand just a bit more angle than the Bus. The axles are the perfect length and the stubs are exactly what you need. I have more faith in the factory bits than any of the current Chinese conversion crap. You could source all of this from a Thing also but oddly enough, the used Porsche stuff can typically be found cheaper.

I think people run the stock axle without the clip.


I bought some SAW axles a long time ago so that's what i use, but i think they are the same length as stock. Only the splinse are longer and i'm pretty sure i don't have clips on them.

Empi makes a "race" type 2 cv that has i think a 21 Degree articulation. That's what i'm using. But the ones you have are going to be fine as long as they don t bind up at full droop.

what you need are Thing rear axles. they have longer splines to go with the Type 2 CV joints
