Hello,

I'm trying to collect parts and info about my future SAS. As SAS are not very (Nor little!) common in Spain, today's question is about driveshafts.

I'll be running Marlin Crawler 5'' leaves in the rear and 4'' ones in the front.

Today I've been in a salvage yard where they've one Hilux with live front axle, like the one I took my axle off. The stock front driveshaft is a double cardan joint one and the right length for a solid axle. Do you think I must buy it? I suppose that maybe it would need to have a long slip yoke welded but it's ok to test and probably modify it?

I've took a pair of pics of it with the cell phone:





What's the difference between this driveshaft and the IFS one? The lenght? Or the flange pattern at the diff side?

Another one is the rear... I won't be putting dual cases. Do you think I'll need to modify the rear driveshaft, put a double cardan joint or a long slip yoke?

Thanks a lot!

David

 

IFS front d shaft u joints cannot handle SAS angles

You need at least an 8" slip spline up front with a CV

You will want to lengthen the front and rear d shafts

 

So do you think the correct would be buy the shaft pictured and weld a log slip yoke?

And the rear? Only lenghten it or I also need a doble cardan joint?

i couldn't run a CV joint on my front shaft because of the angle. i know you can clearance them for more angle, but without duals i don't think it would be enough.

 

This is something a bit extrange isn't it? I think the good think about CV joints is that they are good to save the steep angles aren't they?

i used my old IFS shaft ends... but welded them to square shafts. they were a lil bit of PITA to convince to go into place at that angle, but they did it and have been that way for a year.

 

I just put a 8" slip on my front DS, and it's been fine. The rear, I don't think has had any changes made to it. But, I'm not lifted way high either.

 

Thankd Dingman,

And are the stock 85 DS as the one I pictured in that Hilux? Those Hilux weren't sold in the US, they hare a hybrid, newer body with older frame hehe

An IFS CV shaft can be modifed for more angle:

U-joints can handle more angle than even a modified CV joint and they are shorter overall, so the shaft angle is somewhat less with 2 u-joints and with one and a CV.

 

Im running a pair of high angle drivelines shafts. a clearanced CV out back and a U-joint up front, a CV can not handle the front end angles.

 

Wow, what a lot of possibilities...

Then... I've my stock driveshafts of my 94 4Runner and a long travel slip yoke I've bough with the SAS kit.

What have I to do?

- Shortening the rear driveline and putting the long slip yoke and using it as front DS?
- Clearance front CV shaft and lenghten it and use it in the rear?

I've also the possibility of buying a front CV driveshaft from a solid axled truck...

Sorry for asking so many times but I'm new to DS tech...
