just been told kzj78 front diff head has to be a high pinion head. a rear one doesn't fit in the front. is this correct?
kzj78 front and rear, 130 185 surf rears, other hilux front and rears (not ifs) all fit each other? forgetting ratios.

Will fit in just have to change the steering as there a drag link the runs under it

so with cross over steering a normal hilux/surf/rear prado diff head would fit? bolt patterns all the same?

If you ran hi steer a hilux front or hilux/surf rear will fit in front

Hi, yes that is my understanding, except if it is a toyota electric locking diff housing.
Cheers

Can takes a bit of grinding tho

electric locking prado rear diff head on TM but he just said no actuator with it. he's got one but wants 500 for that. so unless I can find actuator a LOT cheaper than that i'll go back to original plan of auto locker in front.

You are wanting to get a locker into the front of your Prado?
Fitting a rear locker to the front (if it is possible), then having to change all the steering and then get a cert for the steering modifications will become a very costly exercise.
An auto locker is a hell of a lot lot cheaper. It can be a bit of a nuisance offroad with the auto locker in the front but I have one and it is good. I have to do the odd three point turn due to the locker but it is a pretty good compromise. On road no issues as long as you have free wheeling hubs disengaged.

What motor will you be running??? the reason i ask is that the high pinion diff is much stronger than a low pinion in the front, i would be looking at getting a center for the high pinion will save you diff cost at the end of the day. alternatively if you already have a center in a low pinion it will fit in the high pinion will just need new side bearings. my 2c

ok, just not sure how much room there will be when its up to bump stops. will look into it.

I have a couple, this was the plan.

A mate of mine used a low pinion diff when he sas'ed his 185 surf. It was the easyist option for steering, panhard, sump clearance.

He might pop up, there is a thread here about it somewhere

Yes. Absolutely.

I ran a normal hilux head in my prado housing with different steering.

Thats me!!! Yeah shes no worries, havnt read the rest of this post so it may already be covered but the main issue is the steering needs relocated to the front of the diff. With that you loose the steering damper mount on the knuckle end. Unless your running leaf spring (no panhard) then you will find it difficult to fit on the front as well.


Deff do-able though.

P.S. Hi Glen

Just realised what you wanted to know for..............you have the 185 too. Dude thats sucks. After doing mine I realised how easy the 130 shape Surf was to SAS.

Anyway if you have any issues or questions with doing your PM me and ill do my best to answer, im not on here a whole heap but will reply when I see them

Cheers

cheers, will do, won't be happening until about march/april, just trying to make a plan and get all the pieces together.

I kept the hp and lsd it just a matter of matching the carrier bearings

what steering did you use? probably in your build thread but quicker to ask.

problem is with the 130 I would want to change the diff and the motor. I've had petrol and diesel 60's, 61's, 130's and now a 185 3.4 v6, quite like the 3.4.

what steering did you use in your 185?
