Outer Limits 4x4 Board

hi all

I just bought myself a 80 series front end to put in my 4 runner but the diff is from a full time 4wd 80, i was wondering how i go fitting FW hubs to the 80 diff.

I've heard that you need to machine 7-8mm off the end of the cv then regroove the circlip groove, is this the way to do it ?

are there any other options ?

or any factory cv's that i can use ?

Thanks

Gav.

im pretty sure u can put hilux hubs on them u should be able to take ur fw hubs off ur runner adn swap them over. ive never done it personally but heard it can be done

From what ive been told the cv spline is to long to fit into the FW hub fron the hilux/4runner

you buy them from ebay maybe 250 bucks for the pair.

undo 6 small nuts, take off dust cap then circlip. Put free wheel hub base on, do up 6 small bolts again, put circlip back on, put rest of free wheel hub on, do up 6 hex nuts on free wheel hub


Its all very simple i did my 80 but i did the whole part-time conversion. Search ebay sellers for the 4x4 shop.

(BTW the whole conversion is the hubs plus 1 thing is changed in the transfer so that centre diff isnt always locked.)

I am pretty sure it is the other way round. I thought the CVs for part time hubs are longer by 8mm???

yeah CV's for full time hubs have a shorter spline, FW hubs won't go on.

right once and for all to clear things up.

I own a 93 landcruiser RV which was full-time 4wd from factory. the cv spline on early model 80 series ie 1990 - 1993 were longer by 8mm than 94 and upwards 80 series.

I myself have put freewheeling hubs and a part-time kit on my landcruiser.

I have no knowledge of free wheel hubs off hilux / 4runners and how they fit. I brought AVM free wheeling hubs specifically for 80 series landcruiser. One hub size fits all you just need to put spacers in on early models. Which most kits come with btw.

If i understand your intentions then you are looking at putting 80 series diff in the front of a 4runner which would mean that all running gear in the front would be landcruiser.

You may already have hilux / 4runner free wheel hubs laying around but is it worth putting them on considering they were made and designed for a much smaller / lighter car.

Spend the money and do it right the first time, the hilux / 4runner hubs may last forever but in my opinion $260 for brand new free wheel hubs designed for the diff you are running are worth the money if only for peace of mind.

Otherwise hilux / suzuki / landcruiser all use aisin hubs so maybe shoot an email to aisin and see what they say.

See my previous post on fitting it is really that simple.

first pic is full time hub on my car, second is parttime.

Ok this is how it actually is

i have a 1990 80 series , a1998 80 series, a 1986 model hilux and a 1980 model hilux

both my 80 series were full time when i bought them

1990 -1992 (until update in 92 when the big brakes and 4.5 came out)
full time and part time run the same length spline

due to excessive spline wear in the early model full time cars
they increased the spline length in the up date for the full time models to increase surface area
1992- 1998 full time have longer spline

i am personally running hilux asian hubs on my 80 with the 1990 model cv's

these hubs are much stronger than the crappy AVM hubs suppied in part time kits

so the answer
if you have the early front end
your hilux hubs are the best hubs money can buy
if you have the later model diff with longer shafts on cv's its easy to shorten them and cut a new curclip groove
all long fields are built to the longer size so any one running asin hubs with long fields in their 80 has done the shorten mod
its comon knolege

again, pretty sure that is arse about.

94 and later CVs have longer splines, drive flanges for fulltime 80s are deeper to improve wear on the splines.

I changed my CVs in my 1990 model for 94+ CVs and the flanges are different.

as above, the early 80,s (90/92)cv,s are shorter
you could buy the spacer if you dont want to shorten your cv, and use the lux hubs

info i had was from the marks 4x4 guide supplied with kit, is possible it could be a misprinted copy or i remember wrong. As for AVM hubs being worse than aisin generally this is always the case. Oem equipment is almost always better 4x4 wise when your talking driveline. But when i looked at twice the price i didn't think it was worth it unless i was going to turn it into a comp truck.

Sorry if i mixed things up. BTW thrashlux is this from personal experience that you say the AVM hubs are "crappy" as i haven't read anything but positive comments on them. if the aisins are stronger ill have to see about keeping some money aside just in case they do fail although so far they've been perfect

Asin (the lux hubs) are stronger than the $260 AVM's... although i *think* you'll need to use a solid axle collar on the Asins if they're off a IFS rig, because my crusty memory is telling me the IFS CV's and Solid axle cv's are a different spline count where they go into the free wheeling hub.

this does work but.........
the spacers require longer studs also the dowel pins are not directly engaged this weakens the whole set up
the 8mm studs are marginal to start with if you add the spacer they are even weaker

then they fire off into the bush shearing all the studs off like this

after that if your bearing carrier is not stuffed you need to drill out the studs and look for your free wheel hub in the bush beside the track

found it !!!


its best to shorten the cv's i know from first hand experience
unless you r a pussy and dont drive hard then the spacers will be fine

ok i think maybe i am a little hard on my hubs and studs
but yes howsie its worth getting the asin's if you can they are much heavier and stronger than the avm or warn hubs
longfield will not waranty their cv's unless asins are fitted which is funny cause you need to mode their spline to fit them

strike #1



strike #2


strike #3


why me



maybe diff locks 8000 rpm and wheel doing 80kph at a standstill grabing a rock

So after all this im slightly confused as to what being said

ill just see what i can get to fit and ill get back and let you's all know how i go

Thanks anyway.

ok
you have 4 options

1 early model 80 cv's with your hilux aisins direct bolt up
2 late model 80 cv's with your hilux aisins plus spacers
3 late model 80 cv's machined with your hilux aisins
4 late model 80 cv's with AVM or warn hubs

strongest is aisins with no spacers so option 1 or 3

hope that helps clear the mud a bit

Where can I get the spacers????

Ok got some time today to try and see what fits and luckily its the shorter cv and my hilux hubs are just a bolt on fit

The diff is from a 10/93 model so i just scraped in.

If you have the long c/v, put an extra circlip behind the one in the groove and it is sweet, a little loose but still encapsulated with the free wheelin hub selecter holding the c/v from popping out any further...drove mine around for a couple of years like that.
Andrew

sounds like a good idea for track side repairs.....ill be sure to carry a few extra circlips with me now

I tried the extra circlip but found the end of the axle then hit on the ASIN free wheeling hub

what brand of aftermarket CVs do people recommend and where sourced from for 80 series daily driver GXL?
not after longfields or anything just a non $50 ebay CV that will do the job for towing/driving. bit of offroading etc.

cheers

Twon

NTN are suppliers of OEM CVs and other stuff to car makers. They are available through Don Kyatt and elsewhere. There are other Japanese made aftertmarket suppliers, make sure you verify they are Japanese made. at the moment I cant remember the brand I used
You will be looking at close to $300each for aftermarket Japanese made CVs, so Longs maybe arent a whole lot more expensive.

anybody else had recent experiences in replacing 80 series CVs?
do repco or anyone else sell a decent replacement?

i just put two new cvs in my 93. Got them from all 4x4 at kotara and they were 125 a side, with new flanges (they are the later longer spine ones, as an upgrade/repair)

As for quality? who knows, but i've generally found all 4x4 to only stock reasonably good stuff, and often genuine parts too.

I will bet you a Chinese CV that if you got them at that price, they are Chinese made.

When I blew a chinese CV, I spent as much repairing the other shit it smashed as I did on the Japanese made replacement.

Probably is chinese made, but doesn't necessarily mean poor quality. Only time will tell I guess. I bought cheap cvs from the same store a few years ago on my last 80 series and they held up well.

I do think though if you spend big dollars on big tyres, lockers and plenty of engine power, you're a fool to be cheaping out on the cvs. People seem to balk at the price of cvs like longfields, but wouldn't think twice about spending the same amount on arb air leakers.

thats a good point. I bought cheap ones when I knew no better, I also thought they stood up well to lockers and 35"muds in the 80 until one shat itself. I could have bought Longs for the original chinese CV price plus the repair bill and replacement when I blew one. Oh well, meh!

longs are great but you have to have part time and be serious about how you are going to use them or they are probably over kil
i have a set of $120 cv'sper side i got from driveline services in my full time touring truck with turbo diesel it also has lockers andi am not scared to use them
and a set of longs in my twin turbo supra powered part timer truck (though i do tour with it as well)
but i would never punish the first truck like i do the second
if you had a tow rig truck or one that has no locker i think these cheaper ones would be ok not dirt cheap ones
its like anything, its who is monitoring the quality control that counts when it comes to Chinese stuff they can make good stuff if they are forced to do so
