It really does not matter if anyone else has this problem . You do and it could possibly be dangerous so since you are asking it appears that you can’t fix it your self. So have it looked at as soon as you can . In the mean time check and see if you are still in the warranty period. ---

If it has AWD it’s possible the rear differential is failing depending on the noise. In any event a 2-3 year old vehicle should still be under the original 72 month 70,000 mile powertrain warranty unless you have a _lot_ of miles on it. Take it to the local Lincoln dealer.
