I figured I wasn't the only one..... my hearing loss is due to exposure to loud noise (gunfire, stockcars). Anyone who really blasts their stereo or does a lot of work around loud machinery is either in the same boat as me or will be after continued exposure to the noise. I learned the hard way....protection is necessary for more then just sex! Wrap that rascal and cover your ears!

One thing, it may not just be as easy as plug-and-play. Some piezo elements require a driver (some have integrated drivers as well). The driver uses PWM to rapidly oscillate the element and vibrate, causing the sound. RadioShack has a bunch which have internal drivers and would work on a wide supply range. These should be a relatively easy drop-in for the one in the FJ (although, I haven't looked at it to see if it's something custom, I doubt it's anything more than a regular piezo buzzer).
The reason I say that is the buzzer may be triggered by 12V (most likely), but it could also be triggered by 5V off a signaling line from something. One like this works with 4-28VDC, covering anything in the range. It might be worth it to find the buzzer and put some volt meter leads on the pins first just to see what voltage level drives the piezo.
I wish you luck -- my uncle has had the same thing happen from too many records through headphones, too loud!
Thanks Doublejfj....it sounds like you know what you're talking about. I found this TSB about the reverse sensing system, but it doesn't have the specs on the buzzer.
what bugs me is eveytime i put it in reverse, that stupid beeep.. i am like why does it need to do that.. i do like it when backing..
Note: The beeper does (should) not automatically go on when you are in reverse unless you happen to be within range (48" or less) of an object behind you.

Yea, it looks like you should be able to disconnect the buzzer and put a multimeter (set to DC voltage) on those lines going to it. Throw it in reverse and place something in front of the sensor so it will beep constantly. Read the DC voltage and see what it comes out to when the buzzer is beeping. You should be able to then find something which matches that voltage level and sub it right in.
This would be a pretty cool and useful mod, I think.

My son is a computer techie with all kinds of meters and stuff....sounds like a mission for him!

Just a suggestion. Maybe the power supply to the buzzer could be replaced by a Bright LED lamp that could be within easy sight. Even with your head turned you could still see the flashing. The buzzer can't be using much juice and neither should an LED replacement. Not so bright of a lamp to make it look like you have a light show going on inside though. It's something I have kind of been looking into. If I have the stereo cranked up pretty good. Backing into a spot or looking for a better angle to go up a trail. It's tough to hear the beeper.
