Vit diff centres into W/T

[Badooky]

Gday guys
im looking at a vit front cut to upgrade the engine in my lwb maruti ute
(G16a efi) it comes with front and rear diffs i think they are 4.62s does that sound right ? (early mid 90s swb auto)
can i fit them both into my 4.11 maruti W/T diffs or do i need two fronts

thanks guys

Is it just the centres that come with it, or the whole deal. it would be a good time to do the coil conversion in the rear and use a whole vitara rear end. Bigger bearings and all would handle stress a litle better...

Sorry, don't know if it'll all fit or not.

[Badooky]

Its the complete diffs but a vit diff isnt offset like the sierra so i would need to change the tubes or use the vit transfer case( but its an auto so the ratios just arent low enough

[Badooky]

can anyone help it would be much appreciated

Sorry badooky but you must have the wrong section because all that gets talked about in here in rubbish not suzuki tech talk as the title implies. Sorry J/J

I will give it a shot Badooky,

There are 2 diferent crown wheel sizes and 3 diferent axle sizes between a vit and a sierra.

sierra front has the same size crown wheel as a sierra rear and a vit front but it has a smaller axle size than both of them.

sierra rear has the same size crown wheel as a sierra front and a vit front and shares axle size with a vit front.

vit rear is physicaly larger all round and wont anywhere on a sierra (without major mods)

The other thing to remember is that the vit alloy centre is not very desirable, so you will have to swap the vit gears into the sierra cast iron centre

You need 2 vit front diffs of the same ratio, 1 goes in the rear easy, 1 goes in the front, after you change the side gears from vit front to sierra front.
There is a bit more to it, but that is basicly the nuts and bolts of it, I hope this helps.

Your on the right track fellas. Haveing run Vit front diffs in my sierra for years I found the best way is to simply swap the ring and pinion. The diffs you have are out of a four cyl. auto. The ones in the manuals are 5.12:1 and if you search hard enough you can find some 5.36:1 sets. It pays to beat the housing out a little to give the new ring gear enough clearance in case of a knock. The other problem with swapping the ring and pinion is the cross pins are free to move around and a ring needs to be turned up to hold them captive. You could get crude and use a large hose clamp. Another thing to do is to make a ring up to space the outer race of one of the main carrier bearings. The pinion is so small that the whole carrier has to be off set to properly engage the ring gear and the bearing adjuster will bottom out in the thread. May not be an issue on the gears you have as the pinion is larger in diameter. Last but not least it is possible to run a Vit front diff centre complete in the rear after changing side gears and the offset won't upset your tailshaft but the hole you punch in the alloy housing on the first rock you hit will pi$$ you off. Do it properly first time and it will last as long as that pi$$y little pinion gear will let it.

Hope this has helped, Andy.

cheers guys thats what i wanted to here it will make spining 32s that much easier until i can afford 35s and s3 RH
thanks heaps

No, cannot do the front vit r&p conversions on your centres they are equvelant 1 litre centres, so you have to change your housings over to 1.3 w/t's which is a good move Maruty housings are very soft and bend easy = bearing failure = trailer home..

32's hey, well i'll race you to it!
Just get a s3 and keep the diffs per normal for now because your going to suffer on the highway. Just keep the diffs for a later date!

do the coil conversion in the rear and use a whole vitara rear end.

hmmm ideas coming to my head, maybe you could use the vit rear and use the rear springs you got now to lift the front?

[Badooky]

what are the differences between 1.3 W/T housings and my maruti W/T 4.11s can i see any differences
what are my complete diffs worth??

I think your centres are smaller but the rest is the same to look at. brakes are all the same to be honest I never really did a visual comparison between the 2. I sold the front centre to a guy in qld for $100 that was all that was worth selling still have front brakes which you can put on the rear and cv's(don't know why) the rest was chucked. If you hung onto them, brace the rear housing and you can put 1ltre lockrights in them but if you bust an axle or cv I think you will find it difficult to find replacements.

[stephen]

Just remembered that the guy I sold my front centre too (mechanic) tried to put varios standard jap 1 litre centres in the car he was working on but something was not happening (cannot remember exactly) that is why he bought the genuine maruty centre from me. so to the right person they would be worth a bit but then that is the same with everything.

[mtzook]

Don't forget about how weak the rear axle shafts were in the maruti centres. After just 1 afternoon offroad, i had twisted the spline (with the detroit locker) of the maruit shafts almost 1 spline tooth around (few mm or so). The rear diff that day bent like a banana on one side, and it bent upwards instead of down from the spring perch. Very strange. Now it's gone WT 1.3's in it. Haven't checked the splines on the shafts for a long time, but it seems to be all good.

That's why i was suggesting the vitara rear end if possible.... Is this why people go with toyota stuff???

steve, are you talking about early 90s mg410 or later mine is a 96 model, i just came back from SuziWest looking at housings and stuff and my housing are identical to sj413 W/T ones. the guy are very confident that they will fit

mtzook, do you know if i can run sierra axles in a reinforced maruti housing

thanks guys

Maybe, but I don't think so, but feel free to call me a lyer. Possibly they have integrated the 1ltr r&p into the wide track centre but then what about axles? Just don't invest any dough until you are 100% sure, I am interested to find out now.

[stephen]

Mtzook is my brother niether of us have and answer for this one, but as said in my last post I am still sceptical of suziwests theory so I don't think they will fit.
Michael and I are talking about the same zook. Michael lives in the us I mod and drive his zook. Since he has left I have done efi, turbo, intercooler, r-u-f, 34" jt2, s3rock hopper.

[Badooky]

Nice
how did you fit the RUF?
what BL do you have to fit the 34s
i wont be spending any extra as the diff are coming with the front cut

[stephen]

Ruf with shackles only at the moment. worked very well for me. But I think high steer is required if you do this with shackles I had done high steer before hand also. Going to coils f&r soon so I did not bother with the chassis extension for the ruf. No body lift for the 34's they fit spoa with the front diff moved forward no problem at all.

[Badooky]

i am wanting to run spua with 32s for the time being. i am thinking of running RUF using a drop shackle with a longer bottem section to allow for the longer spring, what do you think

[mtzook]

When i changed out the maruti front and rear ends with 88 Sierra WT's, i noticed (going from memory here), that on the maruti housings, you could see 2" or so extensions on each wheel end of the housing. Kinda looked like they had taken a bunch of narrow's and widened them. Not sure about that, but there was definitely some welds there, and i never paid much attention to it after that.

These were from a 95 MG410.

[mtzook]

Actually, i think i do have an answer, stephen.

When i found out i had a twisted spline in the rearend of the MG, it was in the shop cause i was having the detroit rebuilt with new bearings and what not. I went home and pulled out some sierra axles i'm sure of it. I definitely didn't have any other MG axles laying around, but at that time, i still had the remains of most of the stock 88 sierra that donated body parts to mine (hence the blue and red colors).

Unless i'm forgetting something that i did to replace the axle, then YES, MG410 shafts can be replaced by stock WT sierra's.

You remember stephen? Same bearings and all, i'm sure of it.

You don't remember because we never had the detroit in the maruty centres. remember it was unlocked at menai when we bent the housing.

[mtzook]

Ok, i remember now. The MG diffs got bent at menai, without detroit, and the splines were ok at that time. It was after i swapped them out with the SG413 WT's, and drove it a few times that i found the axles were stretching a little.
Ok, so now as far as we know, we're back at square one, the axles are not interchangeable.


... I kicked ass going up that hill at menai though. Everyone else needed a locker but me.
