Groaning sound accelerating from a stop.
 

I am a new member. I have a problem w my 05 Pacifica AWD. When I accelerate from a stop I hear a groaning sound. While cruising or accelerating while already in motion it is fine. Only from a stop. I am considering selling the car as it is time for a new car. This issue would be a deal killer I’m sure! Otherwise has been a great car! Never a problem. Thanks for any input at all.
