At first it almost sounded like an exhaust leak. Sometimes it's almost like it's a fast squeak. It only does it when I'm accelerating hard. If I slowly accelerate it doesn't do it. It doesn't do it when in neutral and accelerating. I even tried jacking up the rear end, and then accelerating but no dice. I was kinda thinking maybe the belt until it didn't do it while the rear tires were off the ground. I did notice a little bit of ps fluid underneath. The cap seems to be jacked up and won't seal. Not sure if that would cause it though. Steering is fine with no noises. Here's a link to the noise. Not sure how well you can hear it though. https://www.youtube.com/watch?v=DaKp66MaTbY Not sure how much you can help because I know noises are tough to diagnose online. Figured you might be able to give me some ideas though. I'm on my phone now and it's a pain to type so will try and explain more when I get home.

Does it do it if you brake torque the engine? Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Hopefully it will make the sound when doing that. It's hard to figure it out when it only happens while driving down the road. It almost sounds like the belt now but the belt is only about a year old and has about 10k on it.
