I used the magical search button, found one thread where Royce had said this
It was some ancient thread from 2008 with 2 posts, so i thought i'd refrain from grave digging

"the vitara rear centre wont

you can get the front 26 spline diff from a vitara from about 92 on and put that in the rear of a sierra but tis an alloy housing so wont lst very long

I am not sure if you can take the 22 spline front diff from an 88-92 vitara and fit that to the front of a sierra, but once again its alloy so not strong at all

you can swap the gears themself in to a sierra centre though"

So what i'm reading, is if i get a 93+ Vitara Front, swap the R+P and planetry assembly into my 90 WT Sierra Diff Housing, it WILL work??

And if i get a 88-92 Vitara Front, swap the R+P and planetry assembly into my 90 WT Sierra Diff Housing, again it WILL work??

yes

Make sure your ratio's match. Front & Back

Then it will put you in the shit real quick.

How big is the accord diff in the gearbox?

[lump_a_charcoal]

Mud racers sometimes use a higher ratio in the front, apart from that, it is bad news.

[SuziBlu]

I never actually thought anyone would alter front and rear ratios, unless in extremely slippery country it would only bind up the transfer case to explosion. Even an odd size tyre can stuff things.

[royce]

if you are going to put the gears into your sierra centers then you can use any year front

That's not even funny

Alrighty, thanks Royce.. I'm gonna see if i can track a pair down

[Brett]

i have a front here and i'm on the central coast. pm me if you want

why cant you use the rears????

[BlueSuzy]

Vit rears have a bigger centre/gearset.

oh righto cheers, i got a LWB vit i just brought, i might track down another set of front gears.

[Ben_Sierra]

Even better than different ratios, a mate of mine had a great idea for a 4WD burnout car.

Put the front diff in upside down. Drive to the pad in 2WD. Put it in 4WD and let her rip. She'll just about stand still and the rears spin one way and the fronts the other, should make for great viewing

I have 5.12's... i dont think they are worthwhile... they are too low in 2H and not low enough in 4L... I'm running them with 31's atm. When money permits, i'll be going to 3.9's and 4:16.1 or 6:5.1 tcase gears.

Just my 2 cents. Cheers.

im going 5.12 diff gears and 6.5 transfer case gears on 31s my zook is a trailer/comp rig
i already have 4:16.1 transfer case gears which im selling

Yeh, 5.12's with reduction gears would be intense... mines a daily though. So reductions gears would make it too low... and already, my max with a 1.6 is about 100Km/h because it just revs its tits off. haha so i cant go any lower in high ...

100Km/s on the taco for me is actually 80Km/h actual speed. So thats a Give or take 20% reduction in high... you just dont see that in low though unless you have the tcase to back it up... Hence why i want to go to 3.9's and reduction gears...

[coneykid]

Ok, I bringing an old topic up again. How much reduction will you gain in doing this..
Is it around 30%.

What are you starting with? NT or WT 1.3l ratios?

I had 4.8 centres with 31" tires and got about 20% reduction. bigger the tire, less reduction.

[coneykid]

i have 3.9 centers. 31 inch muddies..
and i now have (thanks to usher) 1L transfer case.. would all that make good reduction??

sorry to boost up a hot old thread here

I need a new diff center and there are none in townsville. what what royce has written above am I understanding correctly that I can pull the diff center out of any vitara front diff and fit it into my 1.3WT rear diff?

thanks

Not the whole centre, just the Ring and Pinion (the "Gears") will fit any 1.3 Sierra carrier. Vit/GV front centres come in 22 or 26 spline versions and a variety of gear ratios, the Sierra uses 22 spl in the front diff and 26 in the rear diff.

None of the Sierra ratios are the same as the Vit/GV options, so you will need to find 2 Vit/GV's with identical ratios to replace BOTH the Sierra diffs at the same time.

[Rossco]

I think there are two vitaras at the wreckers with both their diffs. so as long as I get both ring and pinions from the front and back I will be aright. im assuming the front vit will go in front sierra etc. how hard is it to replace just the ring and pinion? its my dd and I need it to get to work. is it something I can do in a day without fucking up with basic tools? I have never seen a diff center before.

[Rossco]

or wait the vit rear wont fit so I have to find one vit front 22 and another vit front 26 spline both with the same ratio?

You want TWO Vit front diffs... When you get them home you strip the crownwheel and pinion shafts out and then fit them into Sierra carriers using all Sierra hemisphere bits...

You need 2 sets of Vit fronts. And if you have never played with a diff before then i'd advise you to get someone that has to set them up otherwise they will be very noisy and not last very long. Diffs need to be set right and getting it just right is very difficult without the right tools.
