If I accelerate from a stop with the steering wheel turned I'm getting a rumble that I can feel through the wheel and gas pedal and it has a kinda deep throaty sound. This doesn't happen at all when the wheel is straight or even close to straight, only with the wheel turned a significant amount. In all of my old 4WD rigs this would happen if the front hubs were locked but that was expected, it was called chunking or something similar, but I've never experienced this with any of my Subarus. Has anyone else noticed this? It seems to be getting worse as the miles build, wasn't noticeable at all when new but after 11,500 miles it happens almost all the time now.
