Most of the diffs found here, have LSD. Thanks to the snowy season.

It's probably no surprise that Hiace leads the sales here too  .
Some interesting facts:
Engine is 2KD-FTV D4D diesel.
All the new Hiaces comes with LSD.
Automatic transmission is A340E.

Is this a first? A Toyota that Australia gets but NZ misses out on?
Whilst I am not one to be terribly intersted in vans/people movers, I am sure that a V6 powered Hiace would be a better basis as a people mover than the FWD Tarago/Previa. Styling wise it look much better too, better styled (although a van) than most of Toyota's current whitegoods-like passenger cars.
Funny how Toyota in 2004 can fit IRS to a van but Ford Australia persists with leafs on the Falcon wagon.
I know that the Territory will take over from the wagon in the marketplace but even so....

we do get that shape, as jdm imports only though.
a leaf spring live axle set up is actually better for commercial vehicles then irs. cheaper too.

Yes I know bit I meant as an official Toyota import, not grey market used.

That is conventional wisdom, but a Hiace is going to carry much heavier loads than a Falcon wagon, and if Toyota's R&D showed that an IRS is suitable for the intended use, then it should be fine. It must have not cost that much more anyway, otherwise money hungry Toyota would not have bothered.

the irs model was actually first used in japan as a ppl mover, irs suits that better. they must have found it goes ok as a comercial as well, be interesting to see what courier drivers etc think of it.

thats prob more to do with size of the vehicle than the rear axle... you cant really compare a station wagon and a commercial van...

Take the comparison from when Holden went to IRS for its utes compared to the Falcon ones then. The Holdens got owned because they could only carry about half what the Falcon's could weight wise.
Leafs may be crude, but its a hell of a lot easier for them to make them take a big load.

Maybe, but the Hiace IRS can take a 1200 kg payload. No station wagon - unless it is a Hummer wagon or some other monstrosity - can match that.

Coil springs for comfort leaf for weight

All the Hiaces sold here are IRS. Look the pic I posted, it's commercial and you can see the IRS setup there.
summary:
G series 8"(?)
Differential ratio is 1:3.909 except the automatic which is 1:4.100
LSD is standard fitting.
Width between shaft flanges is 270mm. Flange PCD is 4x83mm.
This applies to modells sold in Finland (might be valid in rest of the europe and world).

Just out of interest, does the owners manual of your car stipulate diferent carrying capacities for the leaf and coil versions of the wagon?
I assumed that the rear suspension difference between the base and custom wagon was mainly due to keeping the price down for the cheaper model.

G series is 8 inch I've lost the link to the axle codes site to say what the 52 is
As for the crowns Dad and I have read in one of the manuals we have that there is a different load for the coil vs leaf spring set ups. It wasn't to keep costs down.
If you really want the figures I will dig it up.

G did stand for 8", for sure but is it still valid?
I mean, the transcode marking system, is it still the same?

G52 is the transmission code (5-speed manual). The axle code should contain 3 digits, eg G295.
|

I'm curious
