I hope that you can translate this somehow but i don't understand a singe word you say, but i still comprehended everything you explained by the pictures that you showed, like the car lines in the sand and the worm gear. If i could i would give you 2 thumbs up, because i couldn't understand a torsen differential in my own language but you managed to make me understand, id give you 2 thumbs up. Keep up the good work!
