An issue that I just noticed yesterday...
Just some background info... my vehicle is a stick shift Z51 that just passed 1000 miles. Driving it home on 12/8/13 as I was backing it into the garage, I noticed that my steering wheel was really hard to turn (almost felt as if it had no power steering) and notice that I had a "service rear axle" warning in my dash. Shut off the car and went to bed.
Next morning, I started the car and see that the warning light was no longer there. Called a local dealer and was told to bring the car over and they will take a look at it. Brought it to the dealer and they said they will see what codes are stored in the computer.
Got a call the a day later from my adviser saying they found some codes in the vehicle but was told that it was some thing related to the communication between the modules and that a reflash took care of the issues. He told me he wanted to keep the car for an extra day just to make sure everything was ok.
Got a call the following day from adviser that everything was taken care of. So I went to pick up the car. Adviser told me that they checked the differential fluid and notice it was a smudge on the low side, so they topped it off. He also said they reflashed the ecu and solved the module communication problems. I got in the car to drive off, engaged the clutch, put it in reverse and gave it some gas to back out of the parking space. As I let off the gas and engaged the clutch again to shift to first, I heard three clicking noises coming from under the car right as I engaged the clutch. I was able to duplicate the noise again in the parking lot of the dealership. As I have never heard this noise before, I asked a tech to check it out. Drove it around the block with the tech in the passenger seat. I was able to duplicate the noise only once, which he also heard. But by that time, the noise was a lot less pronounced. The tech told me that its normal drivetrain noise and said I should not worry about it, so I left the dealership.
In my drives today, I notice that the sound only occurs when shifting between low gears and only at very low speeds (might due to the fact that shifting at higher speed, the sound is blocked by road noise) Furthermore, the sound only occurs as the clutch is being engaged immediately following being on the gas (no sound when shifting from neutral to first or neutral to reverse from stopped). And the sound is louder when the engine is cold.
I'm worried that this sound is not normal, especially since I haven't noticed it before. But I might just be paranoid as I just got it back from service. So I'm seeking some guidance and advise and want to see if anyone can shed some light as to what it might be. If anyone else have heard this in their vehicle, please chime in.
