So these will be going in tomorrow

As far as drivelines go what do you guys suggest? Should I use my front cv and stick it in the rear? And run single Ujoints on the front shaft?
Or would I be fine with just shortening the rear shaft?
Anyone with experience please help me put here

Not enough info.

Solid axle or IFS?

Got a CV in the rear now or not?

Lift?

Need long travel?

trail only or street too?

my rear shaft with standard u joints seems to be fine. I have heard of guys having good luck with CV's in the rear and vice versa-getting vibration.

I would just recommend for the rear shaft that you get it done 'professionally'--make sure it is balanced.

you are gonna love the dual cases...I can idle over stuff that jeeps get trashed on


he gave you this information:

I CANT wait for the weekend!
Im going from a automatic to this so Im even more excited.
Its going in my 85 with solid axle of course. This gets driven on the highway quite often at 70mph
Its getting chevys in the rear and RUF.
Anyone else use no cv in the rear?

I don't know if it's a problem in 4runners, but the "horse collar" crossmember gets in the way of using the front cv in the rear on trucks. I'm using a non CV u joint in the rear or mine and DD it, but mine is stock height IFS, I can't say for certain, but I think you would need a CV in the rear if it's lifted. As far as the front goes, are you going to make your own front driveshaft? It'd save you a couple hundred bucks...

Wel I have a 2 pc DS with a CV in the rear and my pinion rotated. No vibes. In the front with the SFA a TG long spline kit and a high angle CV and a high pinion front diff.

The front is great for wheeling but the TG long spline kit is only good for about 20mph with my angles (which are really good BTW). A front shaft with u-joints on both ends is going to vibrate like mad. I'd go with a CV front and back.

Any one have experience with a cv in the rear in a 4runner with and horsecollar interference?
Ive got a CV off a 87 front shaft. Should I use that front or rear on my 85?

You wont be able to use it in the front. I've seen others run them in the rear with good results, though. Good luck, and enjoy the duals!

SpecialScottie

Why cant it be used in the front?

malteserunner

iTrader: (1)

The SFA cv's need to reach higher angles than the IFS cv's. Since the IFS carrier is stationary.

SpecialScottie

Oh right but if I clearance it, it should be fine correct?

will that make a difference with the dual cases the front output is moved back about 5"?
if not, 4crawler's cheap tricks has a good write up on cleariing a cv

Nothing about that on my site, but se below:

I was wondering the same thing. With dual cases isnt my drivline angle almost the same front or rear?

4Crawler

iTrader: (3)

With dual cases and front axle moved ~3" forward, my front shaft is maybe 6-7" shorter than the front, angles are probably close at normal ride height, but the front angle increases a lot more under full droop than the rear shaft.

SpecialScottie

So I should be able to use a stock IFS CV in the rear without having to clearance it?

4Crawler

iTrader: (3)

You'll need to check the angles and see. With my '85, I have a clearanced IFS CV in back and even so it'll just barely handle full droop at the axle. When I disconnect the shaft it will not drop all the way to the ground, it binds up justa little past full droop.

SpecialScottie

Thanks 4crawler
Has anyone has any problems with a CV and horsecollar interference?

I have with my duals.

I used two 89-95 CV axles, and shortened/lengthened them accordingly. I knew they were only 20 degree CV's, but for now that works on my 4Runner since its still IFS. When I go SAS, i will have to clearance the driveline. You always want to go CV when you have the opportunity IMHO, because there is less stress on the Ujoints.

4WD Toyota owner magazine just did an article on this very thing
