Sounds like vacuum leak under dash

When I let off the brake pedal and/or turn the steering wheel I hear a loud hissing sound like an air leak under the driver side dash. Anyone ever experienced this?

Yeah, My Dad's 2003 Dodge 2500 6 spd has the same issue, but only when the steering wheel is turned.

Sounds like there is escaping air or something.

Check your power steering...

If your hearing the same noise i was, my PS was near dry.
