    Unhappy Whining sound when in gear and on the gas.

    '03 WRX

    I deserve this. I'm going to come right out and say it. I pretty much asked for a problem. I had work done at a Delta Sonic. DON'T JUDGE ME. I work standard office hours and it's a bitch finding a ride to work. The convenience was too tempting. I am lazy. And I ****ed up.

    It started innocently enough-- I needed an oil change. I didn't feel like doing it myself, so I decided to overpay to have it done for me (I've been using mobil 1 forever and they offered it). Here's where I fell into their trap. The car has 90k miles on it. They know this, and told me I was due for a change of the front/rear differential and gear oil. This is true.. sorta. The maintenance schedule suggests an inspection of it every 30k. I have no idea if it really needed a change tho. So I had them do it.

    Everything seemed okay at first. About 100 miles later, I now hear a whining sound when in gear and accelerating. It is loudest in first gear and gets higher pitched as I accelerate. In 2nd, 3rd, and 4th, it is harder to notice. It is somewhat close to that classic whining sound of backing up in reverse gear.. but with not as much of an "R" sound to it. At 5th it is barely perceptible but that can just be due to ambient noise. I also sometimes notice almost a sulfur like smell... at first I thought it was excess oil burning off.. but it's not quite that.

    Who knows what those Delta Sonic retards did. I didn't think that type of work was easy to **** up. But apparently something is not right. Or maybe it is something completely different. Could it be something as stupid as them using the wrong diff oil?

    Mine is an 02 and has 96k it's always had that kind of sound when accelerating. Cruising sounds normal. Declaration sounds normal. So I just figured it was some turbo noise or something. My friend said his does too. But maybe your are talking and a different noise. Can you get a video?

    Whining sound when in gear and on the gas.

    Check gear oil level.

    Check for gear oil leaks.

    Ask what gear oil and viscosity they used.

    Gear oil change interval correct.
