G Series Diff
|
Sat, 31 August 2002 19:58

With the G series diffs.
What cars did they come in Live Axle form, and ...
Can you fit the LSD from a Supra (IRS) into them?
What model diff is the JZA80 Supra and the Soarers (latemodel)?

Pretty much all Hilux's and Hiaces came with G series live axles. Yes, you can put a Mk3 Supra centre in a Hilux axle or vice-versa, but the bearings are different so you have to swap them. No big deal to do it though.
I don't know about Mk4 Supras, I'm pretty sure their diff is different to the Mk3 but they might still be interchangeable.

Hiluxes and Hiaces are the G series live diffs. The Mk3 diffs will fit - sort off :- . Hilux diff carriers with ratios greater than 4.5:1 won't take the Supra IRS diff (not wide enough) and the ones with 4.3:1 or less might. I am in the midst of this grief at the moment. The nice thing is that Hilux LSD's are everywhere, they are 4 pinion, come in a range of ratios and are relatively cheap, so who cares!
The other thing is a rear disc conversion. Fitment of caliper and disc is easy - just machine an appropriately configured caliper bracket. The main sticking point is the handbrake mechanism......internal drum looks tricky because the bearing holder is huge (105 mm - might be able to use a Soarer backing plate with mods), integral caliper handbrake (yuk), or hydraulic handbrake (is this legal?). If anyone has overcome this problem, please post away or email me. PLEASE! 
Cheers Dave.

I have seen a hydraulic handbrake used before, it was'nt using the calipers on the brake disks! It was using a custom setup on the rear of the tail shaft! It looked pretty cool but I reckon it would be a bitch make work!

Dave, just wondering how much the Hilux diff conversion is costing? I've been looking into do a B/W conversion and it wont cost anymore than $750! This is not including a LSD center though!

Why do Hilux's come with LSD from the factory?
Does anyone know the length of the diff of an AE86 and one of the Hilux? or do the Hilux's come in different widths?
I take it you cannot convert to discs with disc handbrake?

The widths of the hilux diffs do vary! What do you mean "convert to discs with disc handbrake"?

Cost so far:
- Hilux diff housing and axles - $70
- 4.3:1 4 pinion LSD - $350
- axle bearings and seals - $70
I have to get some caliper brackets made and I'll have to modify some backing plates to get an internal drum handbrake. I hate caliper handbrakes. I'll also have to get the Corona Mk2 suspension points welded on.
Hilux diffs come in a range of widths. RN10 - 40 (or so) are about 1410 mm wide hub to hub. Hiace ones are over 1500 mm. The axles are enormous.

One way to do rear disc brakes:
Use MA70 rear disc backing plates. Remove top pivot pin fitting (rivetted in place). Machine central hole to same diameter as Hilux diff bearing carrier (~105 mm) and drill 4 holes to match Hilux bearing carrier. Make caliper bracket and this should incorporate the drum pivot pin. This will limit you to discs that have an internal drum of 190 mm. That means you're stuck with rotors like the MA70 (291 mm) or possibly some Lexus/Soarer ones (307mm) - there might be more but I'm not sure.

Micheal, You could possibly be right! But i'm too confused 
GT, Would'nt it just be easier to use a B/W diff and be done with it?

Aren't the BW's a bit ordinary? If they're the same as the ones out of Pintaras etc, then I don't think I'd waste my time. The LSD's become single spinners after no time and then they moan like a skanky ho after a year. 
Hilux LSDs are 4 pinion, have nice metal clutch packs and can be shimmed up as required. Sure, there's a bit of stuffing around to get it disc brake, but I think it's worth it.

G'day Dave
I was under the impression that while the Skyline and Pintara diffs are externally the same, the pintara is 2 pinion and the Skyline is 4 pinion.

Yeah I thought the pintara was 2 pinion as well! I will using a diff out of a VN or the like which hardly have any problems! And then you can grab an LSD center out of just about anything then, like a HSV, Fairmont, XR6, XR8, T-Series or just buy one already shimmed ready to go!
And the B/W has disks standard, 4 pinion 28 spline!

why not just swap in the Supra crown and pinion to replace the high ratio hilux one... easy.

Because it wasn't a happening thing! I'd have to take pics and show you why it didn't work. Machining a small shim will make it work.
Cool1, I just don't trust those BW diffs. My mum had an XF Falcon and its diff blew after only 40000 km of totally unspirited driving (the car was new and I never drove it). Yep, an anecdote (maybe she was secretly doing doughies at the local Safeway  ) but it left a sour taste in my mouth and I refuse to go near them.
The other thing I like about the Hilux diff is the ability to rapidly and easily swap out the centres. Oh, and keeping the car all Toyota.

Gianttomato,
In your pricelist you mentioned an lsd for $350. Is that out of a hilux as well?
My mum always told me, "The stupid questions are the ones you don't ask".

GT, I can understand where you are comming from! I dont like to use things that have giving me troubles in the past!
However I have drivin BIG V8 Falcons and Crummydores and I have never had a problem with them! The only problem I have had is with the cheap LSD centers that are fitted standard!
After ringing around today, I will be doing the B/W conversion in a few weeks! All up its going to cost me $670. This is $150 for the diff and $520 do to all the work! Only thing missing is the brake fluid and hand brake cables which should'nt be a problem!

so how much do you guys think the diff conversion will cost oyu all? i am most likely going to do a hilux conversion when my cars on the road, but i want disc and i want the same offset to keep my rims. also do you need a custom tailshaft? or can the original (sprinter in my case) be used? i already got a custom one piece tailshaft due to supra box but its mated to standard diff (why bother i reckon).

Well as I said it's going to cost me $670 maybe a bit less if I talk the wreckers down some more!
This is with out a LSD center. I'll get one of these once the car is running!
Once modified the diff will be the exact same width as the stock TA22 item! And it will have 279mm disks fitted with the stock toyota stud pattern!

At the moment I dont care about the ratio as the car wont be drivin for a long while! But I was told that the wreckers down the road from me has some 4.1 or 4.11 LSD centers! One of these would be great but it will really depend on what gearbox and wheels i'm running!

I'm budgeting on 1100 for the lot. For that I will have 4.3:1 4 pinion LSD, 5 stud pattern, 291 mm ventilated rotors, big 2 spot calipers and a functional internal drum handbrake. I'm not entirely settled on the calipers....
I'm looking for some alloy 4 spots that won't send me broke. Do Volvo make alloy 4 spots? Those ATE/Girlock things on the 240 series weigh a tonne!

I'd be happy with a B/W for my sprinter depending on what ratios are available... if you can get 4.1 or 4.3 like you said then that may be the go... LSD would be nice but at the moment not a priority...

Yeah I could of bought a LSD staight up but they want something like $595 for one and its not a real priority for myself either. Anyway I was told that the centers are only about $300 from the wreckers anyway!

gianttomato, if you get the whole set up together for $1100 that sounds like a good deal, i would be looking for something similar for the sprinter so i SPOSE it shouldnt cost much different. and i would way rather drum handbrake cause disc ones are bodgy. just so much stuffing around with things i know nothing about. (housing from this, centre from that, discs from this....)

Last time I priced all the components and labour for a G-series rear end, it came out to $1500...
So $1100 looks like a bargain!

Please.....this is giving me a headache
The only reason why diff conversion guys stick to their B/W shithouse diffs id that there are literally thousands of them out there!!! They dont tell u that they whine like mole, are a faggot to change centres (therefore, ratios!) and are basically weak as piss compared to the hilux ones! The Hilux is Toyotas answer to the 9 inch although it is only 8 inch). Has 30 spline axles standard, all the LSD's are 4 pinion, its a Banjo centre (easy to change ratios!) and there are a SHITLOAD of different types of lockers and LSD centres available (aftermarket that it). For eg, the ARB Air Locker (the best lockable diff in the world), off when it has to be, flick a switch, little air compresser does its thing, whack, ultimate locked diff!!! Or the Detroit Tru Trac centre. This is VERY similar design to a torsen LSD (ie, all mechanical, no clutch packs to wear out), once again, unbreakable. Oh and as for the disc brake rear, i will do a tech article when i finish mine

GT im not sure that the caliper weight would matter all that much on the rear as it will be unsprung weight and you wouldnt notice the weight difference.
but then again some alloy calipers would be preety trick

Um, the extra weight is important precisely because it's unsprung weight. The more unsprung weight you have, the harder the dampers have to work to keep the wheels under control. This is why alloy calipers are a Very Good Thing (tm).
