Hi All.

My Jimny is from 2005. It has M13a VVT engine, R72 gearbox, ABS etc..
Can I fit axles/differentials from a donor Jimny from all year between 1998-2018 or just 2005 and later years? Can I use axle without ABS? Would it pass MOT?
Sorry for my daft questions.

Regards, Gabor

non VVT axles have different diff ratios, but the casings are the same otherwise. if you have ABS then you will need a donor casing from an abs vehicle. Would pass a UK MOT no problem.

For example; I have 2007 vvt axle casings but the earlier non VVT diffs and have no issues swapping parts between them all.

Ideally you are better off with abs axles on an abs car as it's one of the few driving aids actually worth having. Also for the mot it's possible to remove the abs system completely and not get a failure but to have a constant abs warning light on is a failure. There is also the insurance cot notify who will undoubtedly increase the premium.

My current understanding of this subject based on what I could read here and heard from others:

Casing had been made either with ABS or without ABS in the past. I should fit only casing with ABS that's for sure.
After about 2004-2005 the engine was made either M13A non-VVT or M13A VVT.
All (M13A) casing size the same but non-VVT has different ratios. What does it mean? Lower or higher?
And what about axles made before 2004? Was all of them wihout ABS therefore those aren't for me?
How many different variant of axle can be found out there? Four or even more? I just cannot get it...
Educate me please...I feel confused.

Thank in advance.

OK then, Gearing calculation is the key here.

For the gearing avaliable by swapping different parts about see the wiki here.. www.bigjimny.com/mediawiki/index.php?tit...erential_information

and use that information with a website called 'grimjeeper' to compare the effects of changing any given part. www.grimmjeeper.com/gears.html

with enough work and parts it is possible to swap the gearbox, t-box and diffs between vvt and non vvt. its also possible to swap in a SJ t-box or a rocklobster box for really low drive :-)

very versatile is the Jimny ;-)

I realise that doesnt answer your question. Basically anything in the UK with ABS would have suitable donor axle casing from 2001 onwards.
To be certain I would ask for one from a hard top M13 engine'd model.

Ok then. Here is a quick question: would an 2004 ABS axle change my current gear ratio? I guess yes, because all engine before 2005 were non-VVT. Is it correct?

The casing would, but the diff will be a 3.9, where you need a 4.3 to keep it the same. You could swap the diffs over, but that means removing the shafts.

The result would be to over-gear the car, making it slow to accelerate and cause clutch wear. You would also need to swap the front to the same ratio diff if you want to keep 4x4 ability.

The question nobody has asked yet is what are you hoping to achieve? Are you just looking to replace a damaged axle or are you looking to alter the gearing?
If its the gearing you seek to change you only need to swap the diffs, not the entire axle. All the diffs are interchangeable, so you could buy some '98 diffs and fit them in a 2017 Jimny and vise versa.
