Greetings!

My new (used, but new for me) SUV lets out a strange throaty rattling noise when I accelerate. It kicks in around 2300 RPM's or so when I'm driving, but if I am parked and rev the engine, the noise is not present.

Could this possibly be an exhaust rattle of some sort? Strange that it does not happen when I'm parked. But if it's not exhaust, I fear this might be a transmission problem. Any input?

The vehicle:
2002 Ford Explorer
80,000 miles
4.0L engine
automatic transmission
no fluid leaks

Thanks!

Thanks for the reply!

And yes, happens during hard acceleration. Or just normal acceleration. Seems a bit worse for harder acceleration or when the engine is under load, like when going uphil. Sounds almost like a tricking-out resonator.
