someone please help, i fucked my rear diff in my jimny on the weekend, and i am now hunting a new one from the wreckers, but i dont know what engine or ratio my car is/has. its a 2002 model. 1.3. thats all i know really. help would be much apreciated! thanks

[tanshi]

i think they are either 4.1 or 4.3 i believe.
think it makes a difference if they are manual or auto aswell

2002 i think will be the m13 motor

[DavidSoden]

mines a manual, does that help? ha

[tanshi]

i think yours will be 4.1

check your compliance plate to see what motor it is,

it will either be g13bb or m13

then tell the wreckers that your after a diff for a jimny with a *insert engine type here* and manual gearbox

[DavidSoden]

mine is an m13a engine, so you reckon the ration will be 4.1?

[tanshi]

from what i know about Jimnys yes.

pull the diff out and count the teeth is the best way to be sure

[DavidSoden]

thanks heaps man haha that will be hard, i opened the diff yesterday to drain a bit of the oil, and chunks of metal (stripped teeth) came out with it

[tanshi]

should still be able to count the stubs

[DavidSoden]

true haha. well thanks heaps anyway man !

Yep, will be a 4.09. Not many Jimnys had this ratio so good luck finding one, most were 4.3.

I'm yet to see a jimny that wasn't 4.09. The Suzuki literature says only Auto's were 4.09 however this doesn't seem to be true.

I have dismantled many Jimny diffs and most were 4.3, I hunted for 6weeks trying to find a 4.09.

[DavidSoden]

a guy has found me 2, im just waiting for him to call me back with the ratio

[alien]

putting 4.3s in (assuming you can) would be good to correct gearing for a 215/75r15 tyre though!

[zukenutter]

4.09 was up to the 2006, 2006 on VVT models are 4.3, I've heard autos are different but yet to confirm that.

[Bugsta]

I have 2 4.09 diffs I have tried to sell.

Do you still need one David?

edit: Sorry, its front ones I have.

[DavidSoden]

I may need one for the front actualy! I'm not positive yet though. You will
Be the first though if I find out I need one

[DavidSoden]

Zookimonsta, you positive that it will be a 4.09?

Mine is a 08 manual and is 4.3.

As far as I understand, the earlier manuals were 4.1(4.09 to be accurate). If you have the diff centre apart you can easily find out by counting the teeth. The 4.3:1 is 43 on the crown(ring) gear to 10 on the pinion, and the 4.09 is 45 to 11.

The autos I can't be sure.

You can also find out when its all together by doing a rotation test and calculation. I posted a thread on how I did this many months ago.

When I was in need of a rear diff, all I could find was 4.1's I ended up getting a crown and pinion from darkhorse (I think) in Sydney posted to me from his Vit.

Thanks heaps guys, I'm picking up a 4.1 later on today, hope it's the right one haha
