Steering problem with Scania R480 and 50 ton trailer

[Alogim]

So, i just picked up a quick job, with a 50t Caterpillar 637G trailer. The truck is a Scania R480 with of course 480 HP and it is a 6x4. The problem is, it is undriveable, in fact you can not steer while throttling.
This problem happens almost always with all 6x4 trucks, when you throttle, you can't steer very much. Anyone encountered this problem too?

There is easy around 20 topics about " understeering " since the update 1.17 in May

I know this is a problem of understeering. The problem is, with that trailer, it doesn't steer at all, even when braking/not throttling :D Probably all the weight go on the doubled-wheels and the front wheels do not even touch the ground. Any mod to solve this?

Anything more than 4x2 doesn't really work. It's not realistic, but 4x2 works fine with heavy loads

Yes there is ONE mod correcting this very specific issue for all vanilla trucks. I do not remember its name but it really isn't old and a nifty search on this forum would find it.
