Im on the stock pump and have 51k miles. Could this be my problem?
Could be. Usually if your in a warmer climate and you car warms up quicker, then the car falls on its face when jumping on it. If your in a cold climate then I can see it taking longer to be an issue. It's under $100 bucks and with that mileage wouldn't be a bad idea.
