if i could find a good set of jeep diffs i would consider it.

but they would have to be CJ5-7 and they are rare as hens teeth.

[Gwagensteve]

And the front is barely stronger than Sierra without upgrades.

International scout are a better option for a couple of reasons, but there's no good reason to use 40 year old us stuff to save some rims.

If you really want 5 on 5.5, cut down f150 would be the go- 9" rear d44 front.

If I have time ill reply in more detail tonight.

[TZAR]

Doesnt Jonno do custom welding and changing of stud pattern holes. He's awesome........

Back to reality why does it have to be cj5-7 diffs???? is that for the ratio or because anything else would gayify your car too much???

There are some super strong jeep diffs out there, or as Guanasteve said F truck or Bronco diffs.

Or maybe 60/75 series with custom hubs. This way you get big axles full floater rear. Spacers are banned in most comps so that could fuck you over getting adapters made too

[pezz]

Because tj xj and jk have a differnt stud pattern where cj shares the same as a sierra

[tanshi]

if i wanted to be like every body else i would have already put toy diffs under it.

i considered the bronco / f truck route, but massive diff centres on 35s really put me off.

if i was to run bigger tires at some point then this would probably be the go.

[BlueSuzy]

Rocky have same pattern, But whatever you do don't pick rocky

Dana's can be built strong, but the smaller ones from tj's and xj and most jk (D35) are not so strong. A centre stuck in the housing puts me off them.

[tanshi]

asia rocksta while were at it???

$500 for a complete 1979 jeep with dana 44's

its in tassie, i sent him a message any way

What's your budget like? These come in 5 stud http://www.spidertrax.com/products/spider-9

I think sticking with suzuki stuff just for the sake of it being suzuki is pointless. People on here hate toyota diffs but stick a ford alternator on their engine without thinking twice...

If you go bigger diffs do you need to keep a certain width? Have you spoken to your engineer about it?

[tanshi]

Im not hugely worried about budget. though spider 9s might be pushing it!!!

Im not too worried about sticking with zook for zooks sake. but honestly there is something cool about keeping the 5x5.5 stud pattern.

width doesnt really worry me too much i will just cover my tyres with more tube if needed.

and yes ive consulted an engineer

[Zook_Fan]

Yeah I get that and you already have some pretty blingy wheels to suit.

If you don't mind width I'd try to adapt a F150 front hub to 60 diffs all round. That way you get heaps of gearing options, heaps of diff upgrades, probably bigger bearings in the F150 hub and 60's are already floating rear to make it potentially easier.

[kenn]

Joes diffs are looking good if you ask me. The rear is full floating and the axles are bigger and stronger. But if your going to go bigger tyres then maybe Dana's are the go.

[tanshi]

i wont be going bigger than 35s in the next probably 2-3 years

if and when i went bigger it would be linked at the same time.

what are the cv's that he uses?

[kenn]

Mine are Nissan 720s but he's gone with another type now not sure what.

[pezz]

There are heaps of hop ups for d44' even the d30 front, d35 rears are utter rubish

I ran a d30 with 30 spline cromo's, 4.88's, ox locker and beat on it, only down side to it was the ball joints on the knuckles

D44's would be the go. Not a crappy one out of a wrangler though.. they have the light duty axle tubes and are narrower.
i think some wagoneers and j20's had full size d44's

[tanshi]

nissan 720s from what i can find they are 100 mm diameter!.

thats not possible surely

F100 4wd had a Reverse rotation Dana 44 (aka High Pinion) front diff. Certainly much easier to find in wreckers than Jeeps. Bolt pattern was still 5 on 5.5" (139.7mm).

Plenty of aftermarket R&P choices (including 4.88), and lots of locker options. See E-BAY.

Unless your Joe.

[tanshi]

if thats possible then why not cal offroad chromo GQ cvs.

[SierraDan]

Dear as hell and still not that great.

an FJ80 Longfield CV would be better especially when they bring out the 30spline

[Joshyboy26]

just skip it all and go rockwells haha cheap, easy to source, small/easy to package. strong enough so when you want to upgrade to 44s youll be sweet

[gregc]

Is this car going to be road driven?

I don't mean certed, I mean lotsa kms and on road gearing requirements.

I suspect the grand you have in the beadlocks will be dwarfed by the cost of the final hub to hub spend, so if you're not going suzuki, you might as well take any pattern you can find.

No one has suggested using a vitara rear to build your front end. That might get past your fears of exploding vitara front end gears.

After my rear diff is done, front diff will be vit rear too.

My apologies Dan.

I look forward to seeing this rear-front diff once it's in.

I vote for 26 spine though to keep it off the shelf axles, otherwise you might as well go 35 spline and full custom.

What about sierra diffs as planned, but use ring and pinion from low range. Ratios of 4.57 and 5.38 and they claim them to be unbrakeable.

this might end up being the way i go. dad has just picked up 2 new ones of these for his and seeing as he destroys so many diffs i'll take his as a test rig.

but if not i think i'll go with some varient of vitara centres front and rear, and hope cvs hold together.

does any one know of a good build thread some where showing fitting up sierra knuckes to vitara axle tubes? the size difference is pretty big and i would rather not just but weld them up.

I skim read too haha.

I think its a good idea. Ups the strength, keeps servicing cheap, light, and cheap axles. Vitara rear gear sets are almost given away too.
