jeep grand cherokee 2.7 GRD noise

Hello dear jeep friends, with my jeep I have a strange noise for a short time. I think that comes from the drive train. when the car is cold, you hear it especially. it’s a roar and only occurs in partial load operation. so if you keep the speed with a light gas foot. when accelerating and when the speed is reduced, the noise is immediately gone. the car now has 95,000 km on the speedometer and knows no terrain except dirt roads. full gas orgies I also have ve rmieden as well as it went. does anyone have any idea what that can be? for tips I would be grateful. otherwise the dare runs without any problems except that the remote dining has only a range of 5 m ( despite new battery ) greeting rajim007
