modified sierra driveshafts

[small talk]

Has anyone ever used an extra 2 (either front or rear) diff pinnion flanges (the bit with half the uni) and bolted and pressed them together to make a double uni joint arraingment?? the reason to gain extra angle the the tailshaft can turn at before it binds up in setups with huge lift or extreme suspension situations.

If it has been done:
1. did this setup work well??
2. would it be best at pinion flange or coming off the x-fer case??

This could be used when streching wheelbase without the need of custom shafts and also give the aadvantages mentioned above.

Anyone with pics or information please post here, also contructive critisism welcome. People Sh*t Canning my ideas please keep it to yourself.

do you mean similar to the joint in a hilux shaft?? i will look for pics of it

[small talk]

Yes i believe they are called doubble cardan joints.

If u check my thread on driveshafts, hilux ones were mentioned in there. mu can go with WT zook flanges and clearance them a bit for the lux ones.

Not sure on the length of the lux shafts as no one got back to me.

just considering this as sierra stuff would already bolt up, and unis would be the same.

[PJ.zook]

If you mean creating your own double cardan cv joint, then without a lot of work you really cant, as you still need the central pivot point to keep them at the same angle.
If you mean adapting the flange into an existing joint, then if it fits, no reason why not.
Id be interested in this if you do, im making custom shafts soon.

Kind of like a centre bearing in a two piece tailshaft?? to keep it under controll. Do you think it would slop around alot??

not gunna work brock you cant just make your own dc joint. I be seeing skinners engineering bout lathing me up an adapter either this week or next, Il let u know how much it cost.

[small talk]

Sounds good rhett your a wealth of knowledge, can you post up the basic idea or email it to me not sure if ill need this in my zook just ideas in my head at this stage.

thanks.

[Rhett]

when I get it made I come and show u it, if I get time. Im guessing lee will tell u when Ive got it done

[bazooked]

wont work dude tried this a while ago, just flops around like crazy, you need that pivot ball set up andhousing like the hilux shafts

[small talk]

Can some one supply a pic of a hilux style joint. Let me know when your done thanks Rhett.

check on here - site is doing funny business with me.

Whats the difference with the pic above (one piece) and bolting two flanges together?? in my mind i can't see the difference, but thats just me.

here is 1 i googeled

[bazooked]

well that didnt work, here is the link look at fig 6.

i see how it works but why the hilux doubble cardan join works but two sierra flanges bolted together dusnt work has got me stuffed.

EDIT: i see it now but if that inner coupling stops it flopping around wouldnt you still only get the same as a normal uni joint?? as that middle yolk in now kind of a middle shaft.

i think the max angle u get out of a dc is 26 degrees, the bearing and housing support it all, without it it just does not work there is physically nothing to hold the flanges central, ya really need to assemble 1 and fit it in the lathe like i did and its pretty self explanatory as to how it wont work.
