My '94 4Runner SAS
#1
My '94 4Runner build-up (SAS, E-Locker, Intercooler, rear discs, dual tanks & more)
Hello,
Finally, after years of dreaming it, the SAS has become real!
This swap is almost unknown in Spain, I only know four trucks SASed and legal in Spain, and this is the 1st Toyota 4Runner.
My truck is a 1994 Toyota 4Runner 3.0 Turbo Diesel. The odometer reads now 199k miles and still running strong. I've the stock clutch too and it doesn't slips! I love this truck.
It's being more than a SAS, the setup is this:
I think I've forget something...
First day we took off the truck all the IFS parts, the rear axle, fuel tank, exhaust and began cutting:



Tipical POS pile

Ready to regear the E-Locker. I bought it with a broken R&P for 300$

The front ready to grind

The rear axle stripped. Panhard braket was a PITA to cut


Welding the E-Locker beads and the armor


Altought the High Pinion diff had 4.88 gears from stock (Toyota LJ-70) we had to adjust the backslash. Also changed the seals

The E-Locker carrier with the new ring gear installed


Pressing the bearings with the "SST"


The rear cut

Front grinded and ready to weld

The E-Locker with the new R&P. Unlocked position

And locked:

The backslash became perfect

Tacking the front spring hanger


The shackle jig tacked in place

The metal eater hehehe

"Plasmaing" the holes

Hole finished

And the tube welded in place

This is me (The long haired guy) and my friend and welder JuanFran mounting the front leaves


The truck in it's weight


Greasing the shackle bolts

As the shackle angle was good JuanFran began welding it definetively

Front hanger welded and gusseted


Mounting the discs to the hubs. I had to buy new hubs because the old ones were rust-welded to the discs. We applied 16.5k tonnes in the press till the disc broke and still were welded.


Where to pound the hub bolts more confortable than over a wheel?

The rear axle plates cut to accept the discs

Front axle truss fully welded

Front diff armor welded

The E-Locker mod made to the rear axle housing

New seals all around

Testing the rear axle without discs

Fully welding the rear leave hangers


Presenting the axle to it's new friends the leaves

Ready to weld the perches in the 0? driveshaft position

The driveshaft angle. or better said, no-angle

Welding the perches to the axle


My friend welded them in the inside too

"Martacking" the front axle shafts


The new axle seals and the Rock Rings installed

The birfields fully litium-greased
Altought I had all well studied sometimes I need a bit of help hehe

The Creeper Gussets welded

Better view of the Rock Rings

And the backing plate eliminator

The Creeper Gussets are also the front shock brackets

Front axle ready to clean and paint

And the rear one

Axles primed


As you can see we left our creativity flow


Matt black painted


The rear discs machined in the inside and the axle shaft plate in the outside to fit

Testing the Supra calipers

Rear axle hung

Primed the grinded/welded areas

Front axle ready to go


Front axle ready except for the Aisin manual hubs

Hy-Steer installed



And finally, the truck on it's four!





This is me, tired but happy

My Toy and an Opel Frontera (Rodeo I think in the US) for comparing

Forklift time. We were testing the shock and bumpstop location




We stopped when the rear tire began rubbing the bumper




Presenting the front shaft and the lonk slip yoke

I've to say that the Trail-Gear long slip yoke was very bad machined. The outside was off-center to the rest of the yoke, so we had to machine the outside again to center it. I know they're not intended for highway use but we put it in the balancing machine and the shacking was horrible even at low speeds. It could have caused the T-Case or diff seals to leak in a few weeks!
The stance. Note there's no weight on the truck (No exhaust, fuel tank, front bumper, winch...)

Rear shock brackets

The front shock towers with the gussets

Front bumpstops

The rear axle shaft plates machined to fit the discs

Aligning the front


As we where welding we decide to add a dual shock support. We've to gusset it

The upper rear shock brackets

The dual shock (Testing)

The Aisins with SS bolts and washers

And the Sky Manufacturing caliper

I must go now, I'll add more pics later.
Cheers,
David

- Trail-Gear 4'' SAS
- Trail-Gear 5'' rear leaves
- Trail-Gear Backplate eliminator kit
- Trail-Gear Rock ring kit
- Trail-Gear Creeper Gussets
- Bilstein 5150 shocks
- Rear airbags
- Intercooler fitting
- Injection pump rebuild
- Injector rebuild
- Turbo wastegate mod
- New SS exhaust line, 70mm ID with constant-radious bends.
- 8x15 ET -24 Vaska alloy wheels
- Copper Discoverer STT 35x12.5x15 tires with airsoft pellets for balancing

This is the disc we made for the T-Case E-Brake. It has the V6 flange pattern and the 3rd Gen one.


This is the intercooler we're fitting in my Toy. It's from a Mitsubishi Montero/Pajero 2.8TD

The injection pump rebuilt


And the injectors


This is the SS piping we're using for the exhaust. It's 70mm (2.756'') inside diameter. We bought constant-radious bends too.

Those are the constant radius bends for the intercooler (2'' ID)


This is the Hilux tank we're using as 2nd one. A 4Runner tank would be easier to fit but this was cheap and the only one we found in that moment

Looks great david!
Since you are SAS'ing for reliability on your desert runs in the Sahara, I would have seriously looked into the full lfoater kit for the rear axle as part of your disc brake conversion:

I'm glad you like it.
Pics added to the 2nd post. Will update when my friend send me new ones. I was there for 2 weeks, now I'm at home again because I have to work...

Hi David,
That is one sweeeeet rig.
Exactly what I want to do to mine. So how's about I get the kit off Trail Gear, and next Spring I get the ferry to Bilbao, pop over to Barcelona and we (OK, you) spend two weeks fitting it all onto my truck??
Sounds like a plan.

Hahaha Andrew!
My truck is in Alicante, I've a friend there that is the person I trust more in the world to touch my Toy, if not I wouldn't drive 500km to reach him.
There's a lot of English people in Alicante hehe

Hi!
My friend has sent me new pictures, so here they are.
Those are the rear brake caliper brackets. They're made from 10mm laser cut steel. We could have made a simplier design but we prefered to use 3 bolts to hold the bracket to the axle.


This is how it goes in the axle

The rear axle shaft plate, painted and ready

The brackets with its spacers and gussets. The caliper isn't going anywhere!


Painting them

To hold the bracket longer bolts must be installed

And this is how the bracket and brake discs are together


And with the Supra caliper in place


Front axle is ready, with rebuilt calipers, new brake pads and front driveshaft

The Trail-Gear long slip yoke. You can see how we had to machine all the outside because it was off-center.

Angle seems a bit excessive but this is with the front axle hanging. Once it rest in the ground the angle will be less.

Hub, spacer, free wheeling hub and brake caliper


Front axle. I think it will last a little...

We sacrificed the upper crossmember. We need that space for the exhaust to go over the transmission. We fabbed another crossmember that will go below the driveshaft, made to hold the two fuel tanks and also the tanks skidplates.

Have fun,
David
