Did something hit the transferbox or did it just break because of the shock?


Just the shock on landing. The mount may have already cracked, I don't know.
Jumping any vehicle is not really a good idea. Time in the air is time lost (no power transmitted to the ground) and unpredictable landing etc.

I use 215/75s on a standard Jimny with no lift and the anti roll bar removed, and it takes me anywhere I want/need to go- green laning, pay and plays, use around the farm etc. The only 'limitation' compared to a lot of the heavily modified Jimnys is ground clearance, but to gain any more I need to make a lot of changes- lift, gearing, camber correction, extended hoses etc. I don't want that sort of expense and compromise on my daily driver. For a close to standard car you can't really fault it.

If you are unsure what you need to do to your Jimny I'd definitely suggest fitting either 195/80 or 215/75r15s and just driving it. You'll soon get an idea what works for you and what needs changing. I see so many people fitting big lifts and 31s before they have even driven their Jimny off road. Then they break CVs, burn out clutches, snap off shock mounts etc. and end up spending a small fortune on all the little details you need to make a Jimny with big wheels work.

Busta:
Yeah, I already had sort of a bad clutch to start with so I did that thing, now I drive it carefully instead of going up steep rocky and muddy terrain.
This until I decide what clutch to get, that's another jungle.
I have quite fresh friction tires on now and those has done a very good job on asphalt and loose stuff.
Guess they wear fast thou but have done some light drifting with them to get a feel for the car and it's a nice ride.

Just before I was thinking, maybe I should "just" do the clutch, get rear and front ARB diffs controllable from inside.
Or just some others diffs with same functions.
Maybe it can do really nice with that and the studded winter tyres going up mountainpasses in Norway this winter.
Or, I almost know it would, it's a Jimny, there is a reason I saw them all over in the Alps in august.

From what I've read the 80s would not fit without some heightening.
I would concider tyres even higher, there might be some good ones. Maybe I go wider later.
Changes in the transferbox is tempting to.
I'm thinking 3", in case I might want to try bigger tyres to, and get more travel.
More lift and the center of gravity would change thou, but we will see what will happen.

1066Boy:
Sounds gnarly :S
But you could jump over obstacles to. :)

195/80 will definitely fit without a lift or trimming. A standard height Jimny on good tyres with arb lockers would be extremely capable!

I think I get a set plus spare then.

They look quite fast, duno.

Would they fit with chains thou?

About the open/lockable diffs, should I concider limited slip to?
With the diffs open/LSD, do I have to worry about 4x4 on grippy surface at all? What is the actual problem with driving with them on that while locked? To much stress on one of the front wheel sides while turning sharply?

I'm not sure about chains. I guess they would be fine on level roads but might catch if the system flexed a lot.

I don't know of any LSDs available for the Jimny.

The problem with 4x4 on grippy surfaces is that there is no centre differential. When you turn, the front wheels have to travel further than the back wheels and without a centre differential this can not happen. It puts a load on the transmission called 'wind up' and causes accelerated wear and breakages! Regardless of what diffs you fit you can't use a Jimny on grippy surfaces in 4wd.

Thank you for making it easy to picture it, starting to get closer to understand how things works now.

My next question would be, could a center diff also be fitted to make it possible?

In a word, no. No company makes a product to fit a centre differential on a Jimny.

The only option you have for a center differential is fitting either a Landcruiser or Landover lt230 transfer case(or if you've got serious money to burn an atlas). The issue with these are they are normally bolted to the back of the gearbox as opposed to being mounted divorced (short prop shaft from the gearbox to the transfer case)
Mounting them divorced can be done but no one's done it in a Jimny to my knowledge.

I'm going for option 3......complete new axles.....no kingpins, wider front than rear and using 31" tyres to have 16" under the diff casing......and only a 2" suspension lift..... :D always another option!

OllieNZ:
Good day!
How much work would something like that take? Are they hard to get and are there any downsides with those center differential transfer cases compared with original? How do they adapt?

Keithy:
Welcome!
Are you going for balljoints instead?
Fitting any readily made parts or are you making/getting them custom machined?
What is the biggest benefits och going wider front?


By the way y'all. I need a clutch and I don't know what tho choose for these kind of cars.
There are two clutches for Jimny being sold in this shop, are they good for more power to?
If I suddenly decide to put a turbo in the "St. Jimny" to?
There is different woven materials, carbon and graphite mixes, powder metal and so on.
If I had the money to burn on an atlas maybe a Spec Stage 3+ like clutch with carbon semi-metallic full faced would be something, that might be overkill, and it seems like they do not make/stock Jimny clutches.
Just use the Jimny when necessary now, until I got a new clutch in place, which I hope is soon.

Good morning from Sweden! : )

I'll be going wider at the front for handling reasons....mostly cornering.

I've yet to strip the spare transfer box and see how feasible it is to make a locker fit in there.
