hi again also has any have the same annoying buzzing coming from the brake booster. Mine occurs very often as when i depress the brake pedal about 3 or 4 times then the buzzing starts. The dealer saids it normal for the buzzing but i never notices it occuring so often and it an annoying buzzing like every 30 second to a minute. any solutions.

With the noisecoming from under the vehicule i was told that the manifold was not tough enough to drown out the noisy air coming out. It's another annoying sound that you only hear when accelarating with the windows down. It sound like a diseal engine makes in the winter, like marbles rattling under the vehicule.It seems that all the 2003 v6 4runner does the same. Do any one hear the same sound or even notices it.

Master Cylinder Assembly must be replaced to eliminate buzzing brakes.

The "tick" and "flutter" engine noise is normal but if it sounds like a diesel, you may have a case for replacement. Someone else went to arbitration over it and won (with an attorney of course).
