Squeaky/chirping rear when gear engaged cruising
Driving to the airport this morning when I noticed a new sound coming from the rear of my vehicle. It is a very faint, persistent, high frequency squeaking noise that sounds like it’s caused from some type of rotation of something in the rear. Car has 3k miles and changed at 2k with proper diff fluid. Conditions for squeak noise:
60+ mph cruising Car in gear Only on accel and decel (while a gear is engaged cruising) but when the car transfers between accel and decel (like going down and hill and lifting off gas), it ceases until decel engages Taking car out of gear and leaving in neutral stops sound as well Doesn’t start immediately at 60 mph, it takes a few minutes of cruising to start making any noise The sound is high frequency as if it’s squeaking while something rotates in the rear. It’s so faint that I obviously don’t hear it with music on. Not sure if anyone has experience with the sound. |

Sounds like it’s your diff although in my experience it typically either makes sound when cruising OR deceleration, not both.

I had a similar issue and had it fixed by the dealer under warranty. Mine was a high-pitched ringing sounds at low speeds and left turns. It was louder when wet and in the colder months.
The dealer originally inspected the diff and flushed the fluid. This seemed to fix the issue for the first 1500 miles. Upon second inspection they replaced the seals on the driver side. Sound went away for about 5k miles before returning louder than before. They replaced all the seals on the 3rd pass and the sound hasn't returned for over 30k miles now. When I'd lift the car in the air and rotate the rear wheels, you could hear the squeak coming from where the axle/differential mate.

Thanks for the response folks!! I get home tomorrow and will drive from the airport and see if that persists. I bought it from an Ohio dealer but imagine anything, since I have 3k miles on it and extended coverage, would be covered under warranty even if I went to another Chevy dealer. Will likely try a Rick Hendrick dealer since I’m in charlotte
