Friends,

I have a 98 Model Prado SWB and has run 100K miles.

I hear a distinct 'boom' noise (kind of resonance noise) in all gears at greater than ~2K RPM and upto 3K RPM. Below that it does not exist and above 3K RPM it reduces a LOT.
At those RPM, if I put in neutral or depress the clutch, the boom noise vanishes.

Previously, when there was leak in silencer, this boom noise was much much more pronounced. Now with the silencer gaskets replaced, it is a lot less but still there.

Need to find out why/where it is coming from and how to remove it. Is it from silencer, or transmission or maybe that dynamic balancer. (I can see that the dynamic balancer rubber has cracked with age )

PS: It is not a whining/bearing/grinding noise. It is a distinct boom noise and kind of creates a pop in ears also

Any pointers?
