I have the Centerforce DF clutch package, steeda quad and firewall adjuster with stock cable. The clutch, PP, flywheel, TOB, and pilot bearing were replaced in April. The TOB has been a little noisy since the install (should've used Ford piece). The car has 118k miles and has seen quite a few power shifts back in its earlier days.
I've been hearing a little more noise than just TOB whine. When I depress the clutch the whine from the TOB goes away but I hear a deeper sounding noise from the tranny if it is in first gear. I can take it out of gear and return it to first while the clutch is depressed and it may or may not go away. Shifting is always fine.
The trans will have to come out to diagnose and repair but I would like some opinions before it does just so that I can financially plan for more than just a TOB. I plan to replace the ball stud, clutch fork, and TOB no matter what.
1) Do I understand correctly that there is a sleeve over the input shaft that the TOB slides back and forth on?
2) I assume I should verify if the input shaft bearing is worn and needs replacement.
3) Anything else I should check?
4) Can any of these parts cause a small intermittent vibration at 2,000 to 2,300 rpm whether the car is in neutral or unload a driven load?
Sorry for the long post. Any suggestions appreciated.

I really think all tob make some kind of noise, it would depend on how loud yours is. The tob slides on the input shaft sleeve. Now those, aluminum ones can get ridges on the sleeve were the tob rides and that can cause binding when pressing the clutch. Shifters let alot of noise out of the box dont know if you just installed or had it a long time. The drive shaft could cause vibration if the u-joints are bad. Now I never had trouble with my Bullitt yet, but this info is from my t-5 in my foxbody. Hope this helps

I did not replace the sleeve when the clutch was changed in April. That may me causing some problem with the TOB. The TOB is definitely noisier than it should be allowing for some noise. The vibration is whether I'm in gear, out of gear, parked, or moving. I'm pretty sure its is something else but was curious about it being a possibility if the input shaft bearing on the tranny was bad. Just a thought.

One suggestion ... You might want to PM English Bob. I know he recently went through his tranny and it seems like there was complaints about a noise that was fixed with using some bronze bushings or something. This was an internal remedy, of course. I don't know much about this trans model but it is an idea that came to mind when I read your post.

Another person to call who is real good and is in San Antonio is David Kee. He is originally a toploader specialist but he has since expanded and would probably be able to tell you as quick as anyone what to look for without tearing in to it himself. Here is his link below:

I hopes this helps you out ... :~))

Well I know the input shaft on a t-5 needs to be shimed up to load the front bearing it may be the same for the 3650. I cant see the bearing going bad unless it has run low on fluid, or debree got in the race from something else in the trans. I thought the vibration was when you were driving. Check bellhousing bolts make sure they are tight and the bellhousing is flat on the block surface. With the clutch in do you get the vibrations?

The vibration is probably unrelated (I think I have an coil that is working sporadically). Just thought I would ask on that one. The TOB is Centerforce (I know, I know, buy Ford). It was a little squeeky from day one but has gotten progreesively worse. There is more noise than just the normal squeek though and I'm concerned the bearing retainer may be worn out as well. I guess I'll plan for some worse things and hope for the best. I may try to get it in the shop next week.
