To start off, I have a 2013 Jeep Wrangler Unlimited Sport (3.6L). Manual Transmission.
So I've had this annoying chirp/squeak noise happening for a while now and have spent the past few months trying to figure it out to include a trip to the dealership, to which they said they could not hear the noise. The noise sounds like its coming from the rear, I hear it behind me while driving but if I'm in the backseat I cannot pinpoint the noise at all from the rear seats it sounds like its coming from all over the place. The best I can describe the noise is a loud squeak/ chirping noise. The noise is intermittent I'd say it happens every 30 seconds or so but its hard to give a good timeframe as it can be random at times and disappear as well for a bit . I never notice the noise when I first start driving for the day, as in if my vehicle has been sitting for a while but 10-15 minutes of driving and it'll start up. It also does not happen while idling, only while driving.
The thing that is odd is I only seem to be able to hear it when the air-conditioning is on, it hasn't been cold enough to test if I can hear it with the heater on but hopefully I can test that here soon as the weather gets colder. I'm not sure if it has to do with the air-conditioning but my current theory is that having the air-conditioning on is allowing the sound to resonate through the vents and when I have it turned off it dampens the noise enough to where I cant hear it. I've also noticed that when turning left from a dead stop and accelerating the noise seems to be louder than usual, other than that it appears pretty consistent noise-wise while driving down the road. I can't pinpoint it to going down rough roads or hitting bumps either, I can be driving down a smooth nicely paved highway and hear the intermittent squeak noise every 30 seconds or so, but I've hit bumps on purpose to see if that would cause the noise without any success. I've also shaken the shit out of my jeep to see if I could get it to make the noise without success either.
Things ive tried so far:
-Replacing front brakes and rotors
-Replacing rear brakes and rotors
-Dealership replaced emergency brake pads and mechanical parts as well as free'd up snagged emergency brake line
-Dealership tightened Body Mounts
-Replaced Serpentine belt
-Applied Sil-glyde to all bushings that I could.
-Tightened doors and Hatch.
-Removed Jack
-Removed Spare tire and drove around, noise still happened.
-Lubed all door latches and rear hatch hinges
-Tightened all Hardtop mounts/screws
-Lubed all weatherstrip's
My guess is that it has something to do with my suspension but I can't pinpoint what part and its odd to me that it takes a while of driving before the noise starts. I would think if it were a suspension issue it would happen as soon as the vehicle started moving or when hitting bigger bumps. I've also heard the rear seat can cause issues but it doesn't make sense to me that the noise would dampen with the air-conditioning off if it were the rear seat causing issues.
Im currently at a loss as to what it could be and the noise is slowly making me lose my sanity lol. I've scoured the forums trying to find an answer to no avail...
