Ok Thank for all the help, I will take the car to the mechanic and see what we can do cause here in Mexico I might not be easy to get parts and without the car AWD I can not lunch the boat and go fishing

no noise nothing it just quit working and I am wondering if that coupling failed the front passenger wheel should not turn but both wheels were spinning when I got stuck

if the viscous cupling is not fonctionning properly or failed you will not have traction on the passenger front wheel no ? when I got stuck in the sand both wheels were spinning

Thanks for the reply, it was working before I was able to lunch my boat on a sandy beach in Mexico now I am getting stuck all the time and the front wheel are just spinning like never before just wondering if it is the coupler or the Bevel
