Hello All!This is my first post in this area! (I usually post in the 65-73 Mustang area.) I have a 1996 Mustang GT with a manual transmission. I have noticed that whenever I push my clutch in, I hear a fairly loud "whirring" noise. Actually, the noise can be heard if I just rest my foot LIGHTLY on the pedal. In other words, if I touch the clutch pedal at all, I will hear the whirring sound. As far as I can tell, the clutch operation seems fine. It's not slipping, and I have good response when I accelerate...but this "whirring" noise is driving me crazy!  It's almost like a "WOW" sound when I shift, with the "WOW" coming when the clutch pedal is pressed all the way down: wwwwWOOOWwwww. I don't know how long this sound has been there, because I ALWAYS have my CD player on when I drive, and I only noticed this noise about 2 months ago, when I forgot to bring a CD with me!  Please tell me if your clutch sounds the same, and if it doesn't, please tell me what I can do about it! THANKS TO ALL! ------------------

Sounds like a throwout bearing.. It only spins while the clutch peddle is depressed..

T-45 is notorious for the throw out bearing going bad. Hard to believe it lasted this long. If you are changing the bearing, you might as well install a King Cobra clutch while you are in there.------------------

I agree, it's prolly the T-bearing. Mine made the same sound, but I knew my clutch was going south so it was easy to assume it was my throwout bearing (I was right, too).As for a replacement clutch, I would recommend the clutch that was OEM in the '93 Cobra. While the King Cobra is ok, it isn't quite as good as it's marketing leads you to believe. Call Don Walsh at D&D Performance. He was the chief drivetrain engineer at Ford before he retired, and the King Cobra was developed while he was there. He's the one that explained to me the why the '93 Cobra clutch is everybit as good, if not better, than the King Cobra, but with less pedal effort. After my dealings with D&D, I posted an exceptionally glowing report in a thread at Sam's Place because of his customer treatment. He'll get my business for the T-5Z tranny I want when I finally get the cash to purchase one. Exceptional customer support, and fantastic product knowledge. Stewart

Thanks to all for the quick (and helpful) responses! I am fairly mechanically inclined (I do all the work on my 1965 Mustang myself), so I am considering trying to replace the throwout bearing by myself.The only problem is, I can't find a "throwout bearing" mentioned anywhere in my shop manual. Does this bearing have another name? Is it part of a larger assembly? Also, what is involved in replacement of the "throwout" bearing? Thanks again, folks! ------------------

Yes, a lot of manuals refer to it as the clutch release bearing. It's attached to the clutch lever, which sits inside the bellhousing, over the transmission input shaft. The bearing is part of the clutch assembly, and if you're going to replace the bearing, you might was well replace the whole clutch assembly. Especially if it's the original clutch and you have a good number of miles on it. Stewart

I go along with everyone else here... If you're gonna tear it down.. DO IT RIGHT..
Don't forget to replace the pilot bearing in the center of the crank, and have the pressure plate deglazed, while you're at it. You won't get a better chance, and you'll be good to go for a long time.. If you can't afford the whole project, then save up till you can. The throw bearing is only used when you hold the clutch in. I have seen em go 5 yrs making the noise.. Here's some advice from an old pro,... Don't rev the engine when your clutch peddle is in (unless your dragracing ). It will burn out the bearing much quicker..
