2017 JK rear squeal

Hey, I'm posting for the first time. Just recently within the last 500 miles. I've been hearing a squeaking/squeaking sound coming from my rear when shifting from park to either drive or reverse. I can't pin point exactly where it's coming from. Its louder when the car first turns on than when it is already warmed up. I have 2000 miles on the car as of now. If I shift from neutral to either Driver or Reverse there is no noise. But when the brake is pushed down and let go you can hear the squeal. The noise only happens with shifting. When your driving I don't hear anything and it shifts smooth. I checked the rear diff fluid thinking it might be the gears meshing but that is full. I was underneath shaking the rear suspension (part connected to sway bar link not sure the name) with a very slight squeak but I really had to really tug on it and it was still barley noticeable. I do have 2.5" lift with 35" tires and also re-geared. I also have videos I'm trying to post on hear so you can hear it. I have made a appt with the dealer for next week but I'm trying to narrow it down as much as possible before I get there. Thanks a lot for your time.

Do you think it's the brakes? Lots of Jeeps make quite a bit of squealing when put in gear and the breaks are applied. Does it stop when you let off the brakes?
Welcome to the forum! Be careful calling your Jeep a car, not that I like cats but, it kills a kitten every time you call it a car.

Yea I meant jeep,autocorrect and yes it does stop as soon as it's in gear and brakes released and no noise from point A to point B. Only when shifted from Park. I was also thinking it could be the brakes not strong enough to hold the wheels when lightly pressed. They are 20" wheels with 35" tires and stock brake system. Will be down grading to 17" in the summer. Going to put the stock wheels back on tomorrow to see if it changes Any suggestions would be great. Thank you !

Put more pressure on the brake pedal when shifting into gear and see if it goes away/stops.

Yea I do that and it takes most of the noise away. After reading more into it I found other post saying that it is the torque moving through the control arms. So I'm going to spray the bushings with some white silicone spray and see. Thank you

May look at swapping the brake pads over to ceramic pads. They tend to not make as much noise when they slip under torque.

I've also noticed a slight squeak in my rear suspension after installing my Mopar 2" lift.

I was thinking about loosening every control arm and track bar bolt in the rear suspension, giving the Jeep a good shake, giving each contact point a good spraying of silicone lubricant, and retorquing everything.
