ATTENTION! Is it coming from the transmission or the bellhousing? I'm am amazed nobody has thought of a pilot bearing yet. A pilot bearing will make the most noise when you have the clutch disengaged. This is because the flywheel is spinning where as the input shaft is not, thus causing the bearing to spin. Push in the clutch, if you hear it, slowly release it until your friction point. If it goes away when you hit your friction point then the Pilot bearing is a good suspect. If you are certin the noise is coming from the gearbox, then i would tend to think it is input shaft bearings. Input bearings will make noise driving or idle, because they spin anytime the clutch is engaged. Output bearings will really only make noise while moving. Either way I can almost gaurentee it is a bearing of some sort. Try to diagnose the best you can with the information given, if you still can't find it, I'm afraid the only real way to find out is to rip the **** apart. Keep us posted:SNSign:
Please guys..begging for help...weird noise

Yup I tried it....pushing in the clutch.
I can hear the clicking sound at idle with the clutch pushed in.
With my foot on the brake (so the car wouldn't roll) I slowly let the clutch out.
At a certain point when you could tell I was at a certain point of friction (the rpm drops and you can tell the car wants to start moving) the noise was gone.
And for however long I held the clutch at this point, the noise was gone.
This obviously tells me there is nothing wrong with the engine right?
I mean if it were a rod bearing etc the engine would still be spinning and the noise would still be there right?
I also noticed that the car is doing some excessive vibrating.....especially when I shift into a gear and the rpm is between 1,5k and 2k.
It does it really bad going into 5th gear at 1,5k-2k. The shifter shakes like crazy.
So you think it's a bad pilot bearing now?
Thanks for your help bro...greatly appreciate it.

Yes from what you describe interms of the noise and what you are doing with the clutch it sounds to me that it is most likely the pilot bearing. However, now hearing about your vibrations could put a spin on things.
Ok, so your cruising down the road, and you really feel these vibrations in 5th gears around 1.5-2k rpm. Now does it only do it in gear or does it do it anytime the wheels are moving? Go ahead and drive the car to where you can really feel the vibration, and pull it outta gear. Did the vibrations go away? If they did that usually means that you could have a mainshaft bearing or something in the trans going out. Another thing, do you have gears? I have heard of cars with gears in it having vibration issues on the highway. Also sometimes the driveshaft balance weights can fall off and cause serious vibrations. Solution, get a Aluminum drive shaft. A buddy of mine has a 93 that has CRAZY vibrations in all gears but goes away when out of gear, and he swears it is the driveshaft.
I conclusion, most likely your pilot bearing is your noise. As for the vibration, let me know when you feel it most and we'll go from there. Pray it's not the trans.
And just remeber, we are all here to help each other out
so no problem brutha!

Yeah I'm pretty sure it only does it when in gear.I'll try later to be sure.
I dunno...it sounds almost as if it were bogging...maybe that's why it kinda vibrates.
I also wanted to add that when I replaced the TOB, it was really worn and not like a TOB is usually worn.
You could actually move the bearing up and down on the shaft. It would make a clicking sound, that's how much play was in there.
Everybody at the shop told me they had also never seen a TOB wear down like that.
So my guess is the shaft in the tranny is wobbling.
And possibly my vibrations are coming from that.
Could the pilot bearing cause that?
Thanks bro you're a huge help!

At this point I'm not sure. I don't really want to tell you one thing or another until I'm pretty sure what your problem is. If you have some time, replace the pilot and double check your TOB. If that dosen't solve it then go from there. But I hate to tell you to throw parts at a car with out being pretty sure about what it is. Maybe it's worth an hour of checkout time with a professional?
Does it sound like a scrubbing noise? Like something is touching the driveshaft? Does it make the sound worse when you hit a dip in the road or bumps?
If so, check your e-brake cable. 94 to present Mustangs may exhibit this noise over time, see as you set and release the parking brake, the bracket that connects underneath the car in the drive shaft tunnel will bend down and the brake cable will come into contact with the drive shaft creating a scrubbing/scraping sound. You can fix it by bending the bracket back up into place. However, use of the e-brake will cause it to eventually start doing it again. Some welding may need to be done on the bracket to keep it in place.
I had this issue on my 94 GT and have heard many others with the same problem.

I still think your pilot bearing is bad. Just also know that if it has been bad for a while then it puts more stress on the input shaft bearings in the transmission. So it could be mulitple bearings goin bad. But like I said before it could also be a driveshaft, or u-joints causeing your vibration. I can't tell you exactly what it is without driving and hearing the car. You need someone that knows what they are doing and knows mustangs to check your car out. Even if you pay someone an hour checkout time, it's cheaper to know exactly what is wrong with the car, then paying rediculous amounts of money in time and labor to throw parts at the car.
I just had the same problems you are having on your car in my car. If you changed your clutch and did not resurface the flywheel, change the throwout bearing, or change the pilot bearing you are going to have noise. I put a centerforce dual friction clutch on my car and I did not change the pilot bearing and now I am getting noise from that. Also if you put an adjustable clutch cable on your car and you have it too tight, it will put premature wear on your throwout bearing and make the noise. so make sure your cable is not too tight. I am 99 percent sure your noise is your throwout bearing. I have bought throwout bearings bad, they are easy to go out, and will make that loud noise when you are at idle. go in there with the tranny out and change your pilot beaing, throwout bearing, and your rear seal because when you have an oil leak from there you have to pull your tranny to fix it so just change it when you are in there. hope that helps you. peace!

Hey Rickey_Bobby, I have the problem you described! Did you fiugre it out? I have a new TOB so it's not that on mine either. Nothing when stopped, clutch in and revving... and when I'm coming to a stop sign I can put the clutch in and I hear the noise related to a spinning motion (clutch disc?) spinning down and coming to a stop (even before the car does). Seems to increase if I brake while in gear without putting clutch in.
Also, I would describe mine more like rocks or gravel falling/sliding around in the transmission. No hard shifts, pedal is fine, adjustment is great, no slippage....
