Excellent work Nark. Any chance of converting this into a tech article, since this topic seems to come up once a month or so?

i too have done a little bit of reserch into the diff's on all the series.
Hiace diff's are no stronger then the Hilux, all the diff's within a series are as strong as each other.
However An LSD g series is going to take more abuse then a Open G series diff.
I'd also like to correct the weight of a complete hilux LSD converted to fit into a coil rear car is 88 kgs.
cheers
Simon

OK. Amended the Hiace thing.
Plan is to turn this into a tech article. Just don't have time right now so I decided to post it up.
Re: The weights.
There were a couple of G series weights I found. One was 80, one was 81 plus the extra 5 kg for the LSD. Now we've got yours at 88.

Nark I suggest you apply fuzzy logic and say they weigh anywhere from 80 to 90 kg. Last time I looked bathroom scales weren't a scientific instrument!

Ah. OK. AFAIK, all the other weights were dry weights.
I'll append your weight in as a complete converted wet weight though.

I feature in some of those hilux axle conversion posts so I had better chip in. The G series open centre RN25 axle weighs 81kg, dry, and 85kg with an LSD centre, before you fit the suspension mounting points for your car. I know all about dodgy 'bathroom' scales and I have a test weight accurate to 250g which I use to check on the scales, as well weighing everything twice. The std complete RA23 rear axle weighs 62kg.
End of story.
Mitch.
PS: Great work Nark, well done !

Great work Nark
The F series Diffs can also be found under the full imported MS50 series crowns.
I've also been told that the F series is the front diff in a 4x4 Lux??? Can this be confirmed.
Also just a suggestion for this thread, can HP figures be put up for these diffs. I.e. what can the diffs put up with in RWkw

Point worth adding is the need to custom up your tailshaft so that the flange at the diff end, be it Hilux G or F series, meets up with whatever you have coming from the gearbox side of things, or two piece tail shaft, whatever.

Ok with the Crowns,
MS50 and 60 Series: The Austrailian Assembled ones had Borguner Diffs in them, the fully imported ones had the F series diffs. All where drum.
Ms70 and 80 series: I'm not sure if there where Aus assembled ones or just imported, again the imported ones would of had F Diffs. Also disc brakes may have been started on this model.
MS112-On: All F series diff, disc.
I know for a fact that the MS112 and Ms50 have the same width diff and i would safley assume that the rest of them would as well. However there is a slight diffenerence between the AIM and Imported ones.
All crowns are 5 stud 114.3 (Ford) patteren
Like everything people with more knowledge than me please amend this, to my knoledge this is all correct.

read the Toyota ID plate. it gives model, year, axle, gearbox engine and everything. You can work it out from that.

G series diffs come in 2 pinion and 4 pinion models, obviously the 4 pinion are stronger. You can get both in LSD.
Our local 22R bunderas have 2 pinion G series in the rear 4.3:1 ratio. The 2LT turbo diesels usually have 4 pinion G series in rear 4.875:1, good luck trying to get one of these.
Also the front diff of 80 series Landcruisers and Bunderas are G series but have the pinion mounted at the top of the crown wheel not conventional bottom and are therefore called "high pinion"
Useless 4WD info finished
Carry on.

heh
would just like to amend the ms112 crown diff width
i have one and it measures 1470mm disk to disk. also these have an internal drum handbrake, 160mm solid disk. also there was an ms110 at the wrecker and the diff looked the same. these are a 3link + panhard (only one top link). can take pics if theres interest. the 5 stud have a bigger spigot ring to locate the wheels so say good bye to your stock 4 stud wheels.
my bro bought an ae85 with a ms112 diff conversion with ae86 mounts etc. ive pinched the housing currently and put my 3.9:1 locker 4stud internals into it. given it absolute assholes with burnouts/drift etc and it handles it fine (160rwhp 3tgte ke70)
also yh50 hiace G series and late 90's hilux surf (not sure what code was) G series measured 1470 too. 5stud
also i once bought a jdm te71 wreck with hilux lsd diff conversion. after much searching to find what model the diff came from it was actually a hiace yh51 (or 50 series) they have a few different variations in the mounting tho.. some are leaf, some 5 link, some have longer bottom links with the shock mounted to the back of em.
mine was the middle one and was bolted in 'as is' with modified panhard but the te71 links were jammed out a little so had a bit of squish on the rubbers.. when i changed to nolathanes i couldn't do that anymore.  also this diff had te71 disk conversion and the calipers were rubbing on the housing as the disk are too small for it. heh oh and the lsd wasnt original as the axles were jammed up tight to the lsd spring retainers and had broken them
some random F/G info

As alot of us have been studying the good ol' axel swap, and there is heaps of info.. But i think we need a bit of a list of what fits what car, I've been trying to get a G series diff for my RA60 celica and yes tehre is enough info here to do it, but a list would just make it a bit easier.. Two peice tail shaft, what sort of work is involved in doing this ? im not too familiar with the idea..
peace wes
