Re:Diffs VVT on Jimny Non VVT

I bought front and rear diffs from VVT Jimny (43x10 - 4.3 ratio)
My Jimny is Non-VVT , manual gearbox (43x11 - 3.90 ratio).
And my question is...Any put VVT diffs in a Non-VVT Jimny?
I read that rear diff is a simple swap, right? The problem come with front diff, the diff housing is small in Non-VVT Jimny, right?
Is simple to clearancing the diff housing or i need to find a front diff housing from vvt ?
Thanks man for helping.
Lerk.

You will need to grind a little bit off the diff housing

And no problem with axles?

when you try to push the diff in to axle case you will see where the diff catches the axle case just grind the axle case to allow it to slide in
only a few mm to remove

Perfect, it has already been understood.
Only need to grinder the "front" axle case, right? Rear is plug and play, correct?
Thanks for ur time.

I have swapped vvt to non-vvt diffs (the other way to you) and had to grind at the front axle casing a wee bit, thus I would assume that going the way you are shouldn't need any extra clearance?

Yes, if u need to grind at the front axle casing a wee bit (the other way, from VVT to Non VVT), I dont undestand that i need to a extra clearance hahaha.
At final, when I dismount front diff I will see.

The one in the garage is going the other way, that's an old Jimny having VVT diffs (keeping the original transfer box) to alter the gearing for 30" tyres. Unfortunately I've only done the rear diff so far so can't comment on how the front one will fit...
BUT...
When I fitted the Vitara LSD in the front diff of theS200KYS Jimny (machined to suit by Redacted ) I then had to take the angle grinder to the front axle casing as described above...
Having a search back through the Bits4Vits archive... here's a photo showing how much had to be removed -
Note there is a similar notch in the bottom of the axle casing but it's slightly obscured by the "B" in the photo's watermark.
Hope that helps Lark?

A man who has made the swap (non vvt to vvt) has sent me the next photos, similar that ur photos S200KYS.
When I put the both diffs, I will do a DIY.

I can get ahold of NON VVT axles for cheap if thats easier? looking at getting a set of axles to weld up and add gussets to anyway so which would be the best option??

Yes, the gearing will be close I have 235/75/15s on mine (29") and the gearing is great, a little bit low if anything, as it accelerates like a little hot hatch...
Here's the diff and trabsfer box information in the BigJimny WiKi - www.bigjimny.com/mediawiki/index.php?tit...erential_information
So you can see your current diffs will be 4.3:1 and the transfer box is 1:1 and the older diffs are 3.909:1 and the transfer box is 1.32:1
So I swapped the transfer box and diffs from an older Jimny into my VVT Jimny...
