This is the continuing saga of the search for the "holy grail" of a slower running gear for my Feroza.

MM, is the Toyota R151F tranny and TT compatible with the Daihatsu Feroza? I understand they're ...

Been there...... done that and it does give more travel.

As said its a lot of work, and needs to be done properly - wheels falling off due to poor workmanship wouldn't be fun.

A down point is that the wheelbase to track ratio becomes worse making stability even more of and issue. Mines around ...

I've done some difficult trails (long and short) with lifted front diff and welded (actually built up) side gears. The learnings are:

1. CV joint issue is more related to axle rod angle from torsion bar lifting than due to gear welding. Maximum side gear cavities should be weld built up except ...

I keep looking at a hilux front diff ( already running a lux rear on Feroza PCD ) for a SAS but he Feroza' chassis rails have very little hump making it very challenging not to make the whole thing way too high. Diff to sump clearance is also an issue - i'm lifting my motor and creating a weird ...

Thanks gents.

I'm already on 235/75 15s, and have untightened the torsion bar so that the lower arm axis and the wheel axis are now same height (stock specs says lower arm axis should be 30-50mm lower so I'm higher still by at least 30mm but the ride has improved greatly with no scrubbing against ...

Christmas greetings; me again mates.

I've been told that with my 2" front lift, I can do a procedure where I first put support on my chasis on stands to keep the vehicle's height, then proceed to remove the torsion bar and from the original mating mark of the torsion arm and torsion spring re ...

3/ Spacing the diff down, just reduces ground clearance so IMO its counterproductive. Your fitting bigger tires to improve ground clearance ( and hurting gearing.... ) and then loosing it again. Also Feroza diffs don't like dragging on the ground - something I've learn't first hand :x

Thanks MM ...

Just a related question:

If I put a bigger tires, would an increase of 2" in diameter push the axle up ward, say by 1", therefore making it more horizontal and less strained?

No, it won't change your suspension geometry by fitting bigger tyres.

If you want more downtravel, you have to space the ...

Just a related question:

I want to increase further the downward travel of my lifted independent front suspension.

Can I cut off some of the top of the downward bump stop limiter that's welded to the chassis to allow additional downward travel of the front suspension? (I've already removed the rubber bump stop attached to ...

Now that I have an excellently working fossy locker on my IFS; next question is:

Can I cut off some of the top of the downward bump stop limiter that's welded to the chassis to allow additional downward travel of the front suspension? (I've already removed the rubber bump stop attached to the ...

You got it mate.. Fill EVERY valley in the spider gears that doesn't interlock with the other gears.

Hi gents. I'm about to get my spare front diff for the "welding" project. One more question please: If the teeth on the side gear pinion only fits two valleys in the side gear at any time, can I ...

Would you mates know if the Detroit here won't fit a Feroza 1.6L w/ IFS and 25 splines? Appreciate your info. God bless.

Hey guys
anyone interested in a rare Detroit Locker for your Rocky or older Daihatsu?

I've one for sale and willing to let go for a reasonable price. Reason why i'm selling it as i've decided to upgrade to either Volvo C303 or Hilux axles as i've come to a point that the final drive ratios on the ...

You can only reduce the LOW gearing on the transfer case because you dont have any space to reduce the gearing for the HIGH gearing. This month we searched a lot of mechanics and sayed that only the low gearing of the Feroza transfer can be done. Now we are looking for samurai transfer or Hilux ...

Ooops, thanks mate. Afraid I'm not ready right now to tackel such a daunting project as yours. I'm trying to get a spare transmission with the intent of opening the transfer case to see gearing possibilities as you had thought of one time. Wish me well again.

Its easy ;)

Feroza Automatic ...

Hellow MM. I hope you don't mind my ressurecting this post. I've working weld-filled side gears in front now and pretty happy with it. You said yours has a 4.3 tranfer gearing. I'd appreciate knowing how you went about the process of getting your transfer re-geared.

Thanks.


Hi Tansy.... "out of ...

The front differential has now been tested through major off-road trails (mostly old and abandoned logging roads) the traction is awesome and quite effective with no major adjustment in handling on loose surface. The system of "filling-up" of the side gears is definitely superior to the direct ...

Hello gentlemen. It's taken some time to get my spare front diff welded but welding is done now and should be assembled by next week. I hope it can be installed soon.

By the way, I was able to determine that the Feroza front differential is a GM 8.2" w/ 10 bolts but haven't checked how many spline ...

IIRC 25 spline

Thanks. Pardon the ignorance, what does IIRC mean? :)
IIRC=IF I RECALL CORRECTLY :lol:


meece is correct of course - but is being kind.

Some of us have trouble remembering what we had for lunch - let alone spline counts :rofl:

Haha, I thought it was some techie code... guess ...

I'm just as eager to get going but I just finished talking with my friend who will do the engineering build-up weld on the side gear crown and the earliest they can accept it is after New Year (Christmas ...

Oh I see. In that case, where do do the weld on the differential in this process, i.e. which part/s do you weld?

Thanks.
Here you go mate.... Nothing to it...

@Piglet and Skiddy: i think it was the finest scat i have ever see.
I am building a Scat for extreme off-road too, for the competition here in Belgium and once a year somewhere in europe (this summer in Roemenië)
this one have a Rocky 2.8tdi engine and original 5-speed gearbox, with Scat F20 axles ...

Now I've got you all thinking about welding your spider gears .....
Has anyone thought about doing a complete axle swap that includes a locker?
I know you guys won't like this but what about putting a pair of LADA NIVA diffs under a rocky....

nah i was talking to andoy, sorry mouse i do know you have a well modified roza :)

Thanks gents for all the new info I've gotten from this thread.
More and more it looks like getting a spare front diff and having it weld-built up as described earlier is my better value for money option.

Thanks. That eliminates this option.
