I have a 92 with KA24DE. I just replaced my clutch, flywheel, pilot bearing and throwout bearing. The clutch kit is a 4 puck with chromoly lighten flywheel. After the install I started getting a humming/light vibration noise from the driveshaft but only on Deceleration and between 2k-3k rpm in all gears except reverse.

I never had this problem before the install so Im thinking I didnt align the driveshaft on back right? So I rechecked it loosened it and realigned the bracket that holds the driveshaft up... Still the same noise. No fluids came out on the install so I didnt put any new fluids in.

I searched the site for this problem but couldnt find one like mine.. most are noises in trans on accleration or in driveshaft. I read some on Deceleration noise but not within the 2-3krpm like mine

Anyone have any idea?

I read something a long time that "Def" posted. I can't remember exactly what it was, so I'll probably fuck it up.

But I think it had to do with a harmonic vibrations because of the springs (or lack of) on the clutch disk. Maybe you'll get lucky and he'll post.

I have that vibration too, and it doesn't bother me. So I didn't do anything about it. If it's an easy fix though, maybe I'd fix it.

the clutch disc is has springs on both sides of the disc.. kind of like a dual spring but not within each other. I dont remember if it was sprung or unsprung. Everything functions correctly it only makes that noise on decel at 2-3k rpms. Doesnt bother me much either I just dont know if its bad for the drivetrain or my clutch.

well mine does the same thing, but thats cause the joint in the driveshaft is about toast and kinda shakes in the bushing.

Mine does the exact same thing. It's done it for a little while. I've just overlooked it, maybe I'll check it out soon.

I might removed my trans next weekend and check out the clutch.

I notice today that when it makes the noise and i lightly push on the clutch pedal I can feel the vibration.. so I could have a problem with my pressure plate or the pitch fork.
