Weird noise

[Randleman]

Hello fellow truckers,

So recently I've been getting into ETS2 again, but there's something new.
Something I can't seem to figure out.

Every once in a while, a loud sound happens when driving.
A sound as if the trailer gets loose from the truck. Or even sillier: As if the truck sneezes.

Every time it happens, I get a little jumpscare.
But it seems to damage my truck too.
The last two deliveries I had bad results and more than €12.000 taken off my pay because of damage to the trailer.

Does anyone know what this is?
I know my description of the sound is weird, but I don't know how to describe a weird sound that I haven't heard in the game before.

Thanks in advance.

Maybe you could record a video using some recording software?

I guess you turn on realistic way of connection truck and trailer. I suppose that's the matter.
After the connection don't forget to up the legs - just push "T" button. It have to solve it and get rid you of the noise.
