I amnot sure if this is what happened. I stopped playing for a month, now It feels weird. I havent changed any settings, the wheel feels easier to turn, i feel less FFB.I can't feel the car's weight thru the wheel :/ if thats the problem, where to get a replace motor, and can i do it by myself at home?

Did you try turning up the FFB settings?

yea, when i increase it to a point (95 ingame) the FFB stops being smooth, and feels "shaky"

You could see if it's strong when it calibrates. Check the profiler settings.
