Strange Noise

[dogfish1]

Hi guys, I have a query for you as I find this the best place to get answers. I have a 2002 d4d, when I accelerate and get to about 2500 revs, there is a sound coming from the front of my car that sounds like hail on a plastic roof, it also makes the car feel like its hanging back.

Anyone have any ideas?

We had a similar noise on our Rav not so long ago.

So took into the Toyo dealer who promptly took it on a test drive and it turned out that a bolt had sheared on the heat shield and when the Rav hit certain revs the noise would come in.Didn't notice any lack in power though.??
