How to Transform The Fiat Panda 4x4 - Installing A Mechanical Coupler 

I like how you repurposed one of the cup holders as a mounting spot for the lever lol

I think the best pairing for this system are manual hub lockers on the rear wheels, even if you cut power going to the rear, the diff is going to be driven as the wheels move along so even though it's not as much as when it's driven there is still efficiency losses and wear. This also would open the door to installing a simple rear locking diff or even welded without compromising everyday drivability.

Nice upgrade! I had a Vw T4 syncro with VC and sold it because of many issues other owners had with it. That special oil had to be changed periodically, you had to pay attention on hot asphalt roads, not to be stucked on, metal plates inside it could be bended, etc. At that time, I wished some passioned guys like these from Prometeo would designed a mechanical coupling like this for Panda, but for the Transporters. Now, I have a Vw T5 4motion with haldex 4 and rear diff lock. It's better and smarter than VC, but I still need to change the oil and filter, so I wish to change it with a mechanical coupler for safety and redundancy reasons. Hope someone will design one for it.. Until then, a haldex controller will be my next upgrade. That can set the coupling between 100-0 to 50-50. I also wish free wheel hubs for the rear wheels. That would really be a big improvement for your Panda, too. Less rear diff wear and better mileage.

I'd say 500 euros is a bargain. You'll probably save that on fuel and diff wear over the next few years being stuck in 2WD when not off road.

can't wait for the black and white paint job getting done ?

We asked the man AND THE MAN DELIVERED IN ABUNDANCE 🎉

In short, you are installing the same device present in 1st gen Panda 4x4 (the ones from the 80s, wich had a manual coupler, instead of a viscous coupler. The 3rd gen, if I remember well, use an Haldex couple.

I'd like the LSD that they do. Because when you're struggling for grip, you can tell not all 4 corners have power going to them.

Most interesting... Been thinking about something like this for some time, not realizing someone actually already made it! How about a LSD for either front or rear? Do somebody do that? I have been toying with the idea of splitting the handbrake into two levers to be able to brake one rear wheel.

That's a great kit. I have seen it before on UK panda facebook page also but what I wonder is that doest it effect the brain or abs of the car? Because I have got a suzuki swift 4x4 and its ABS system is linked with the 4x4 module and the brain. Some people here disconnect the shaft but they say the car jumps when first starting like not good to do. Yes its more fuel efficent.

Oh, I've seen those! I always thought they were a lot more expensive! (As in: don't even bother asking expensive)

your rear diff mount is done i think that is why you have a rub spot on drive shaft where paint has worn off.

Nice ratcheting spanner @12:37 🤣

What FIAT should have fitted in the factory not the fluid coupling. Awesome mod.

Hi Do you need some great lighting for your car to help you better driving, off-road. We're the pro auto lighting company for nearly 20 year and we're looking forward to do some sponsorship with you!

Is that blue the original rear subframe or is it a newer modified one - if so where did you get it from?

Unless you put freewheeling hubs on the rear, rhere will still be some friction loss from the rear differential.

purchase link?

I thought 169 4x4 are permanent 4x4

great work!, is there available for the panda 319?
