Dedmon, it's not that the motors are more quiet, but the steel gears themselves. The metal used in the HL gears, and I believe their design itself, is a cause of a lot of the ringing noise we hear. My first tiger still has the metal gears and it's obnoxiously loud. I also remember a thread a year or so ago where Pzrwest filled the backs of the gears with some type of resin to deaden the noise made from the gears and he said that was helpful
Found it...

Thanks for the clarification.
I don't think I would try the caulk. I can't see that lasting more than one run and causing additional problems with the caulk pealing and adding debris in the teeth.
I got my replacement motor attached to my board and it's whisper quite. Unlike my original gearbox that is significantly louder, almost grinding sound. I added washers to prevent sliding, but it's still loud as heck! Added some axle grease and it's still loud. I'm quite concerned about this one going out too, just when I got the new one. The teeth appear fine, but I'm too inexperienced to really know what I'm doing.
All this modification stuff that's being suggested, does very little without tutorial for newbies.
Looks like I may have to shoot for the steel gears at rccommand sooner than Iwould like.
