Add me to the list and I've got a 2010, all stock Exedy OEM clutch. The only driveline upgrades I have are Kartboy SS and front/rear shifter bushings. I drive hard at times but I'm pretty good to my clutch and tranny now that I can drive it well.

The decel harsh nasty noise started pretty early on in the ownership, I don't remember exactly but it might have been there from the beginning and I just thought it was my driving at the time. I usually err on the side of "it's a brand new car so it must be normal" so I haven't done anything about it. I'm at 7000 miles now and it's the same. This thread pretty much confirms that it's normal but damn does it sound awful sometimes. I picture my gears ending up like the pic a page back but I figure that's unlikely.

Let's summarize with what we know can reduce noise level.

1. Modulating tire pressures.
2. Replacing rear diff. brackets (not always known to work)

Please add if you know of other methods that could help.

Add me to the list. 08 WRX, ACT HD with Lightened Flywheel. Currently in the shop with the rear of the tranny pulled apart. Wish I had seen this earlier. All parts in the rear flawless. We had it on a lift and listened with a stethoscope and you could CLEARLY hear the rattle coming from the back of the tranny no doubt about it. Looked it over today and everything is good to go... How do you explain this with the mounts and tire pressure? Same decel rattle but car is on a lift. Almost got rid of the car. Loved this car but its like a hot girl who won't shut the **** up. She might bang like a rock star but those aren't songs coming out of her month.

Given the fact that the sound is heard when coasting and gears are in their loose zone (not accelerating, not compressing) it seems logical that rolling with the wheels floating off the ground would be the ultimate "gear looseness zone".

Also your observation about the noise coming from the rear (where the gears are located is'nt it?) makes perfect sense too. The noise is between gears, not at the clutch itself (even though it looks like the cause for the noise is the clutch/flywheel combination). So instead of the clutch dampening the rotational vibrations, some of it is sent to the gears and they do their noisy thing.

I'm kind of torn. My 04 STi's factory clutch is pretty much done at 65/K and I am looking at buying a new one, preferably Exedy OEM. Can't decide if I want to gamble with a new after market flywheel or just be safe and get the old one shaved down.

Are flywheels pretty much GTG after being re-machined? I don't want to deal with the racket everyone else seems to be experiencing.

Can anyone tell me if the problem I'm having is the same on described in this thread? I've read a few pages on my phone and it may be or may not be as many of the old videos aren't playing for me on my phone.

06 legacy 2.5i 5MT. Car has 82k. I recently purchased it and as far as i know it has the original clutch installed. I just noticed a rubbing/grinding/rattle when in 5th gear and I let off the gas to coast. The sound stops if I press gas or brake or take the car out of gear.

Here's a video I made this morning on my phone.

Not much to hear in that video, but it did sound similiar to my car. Coasting in fifth is the easiest way to make the noise in mine as well, and it does go away if I brake or accelerate.

A reputable shop here in SoCal, blames my decel noise not on the clutch (Exedy stg1 HD series + new OEM flywheel) but rather some internal transmission bearings failing. The claim is that it'll get worse over time (it has) but not be catastrophic (that they know of), but should look at a new trans, or rebuild down the road.

Which I wanted a Legacy GT or FXT STi trans anyways...

It's pretty darn irritating as it is I must say.

I had my stock clutch replaced at 80k with another OEM clutch, kept the stock flywheel, and now I have a noise while decelerating. Its only around 3k RPM and sounds pretty bad, almost like a grind, but after reading teiva-boy's post it does sound like worn bearings. Im not too concerned about it, I've read far too many posts of people worrying about noises to be concerned.

Mine still made the same noise after i did the rebuild on my 5speed. The darn shop didn't replace the flywheel and clutch like i told them too. Had been driving around with the noise for a few years, and fiqured when my tranny went i'd replace the other things.

Really pissed me off to get my car back with a new tranny and still makes the noise.

at about half way i put my phone under the car and you can really hear it. when the noise stops its because i pushed in the clutch. so is this the sound that is normal.

That is totally not normal. If it was caused by changing your clutch either something is wrong with the fork or release bearing installation or maybe the linkages connecting the shifter. Better pull that thing again and check it out

I have a 2002 Subaru WRX with manual transmission. I have 72k and had the transmission rebuilt with new clutch and flywheel. Still have the deceleration noise!
I have 18" Rims on my car and set the front tires to 40PSI and rear tires to 35PSI then 35PSI all the way areound. There was no difference.

Has anyone solved this problem?

New clutch directly from Subaru, or an Exedy OEM replacement?

Exedy, my deceleration noise is in any gear and is mainly under 3k rpm.
I would say it is most noticable from 3k down to 2300 coasting.

It is really awful sounding, I want it cured asap!
My friend has a 04 WRX and had a new clutch put in and had the flywheel resurfaced. No noise for him though.

I'm going to ask the exact same question about your friend: did he put an exedy replacement or he put a clutch from subaru ?

If I am not mistaken, there arent many (or any?) with genuine clutch from subaru that are having the noise (except those who changed the flywheel for aftermarket).

I'm no expert but from reading this thread it looks like :

Cure = stock clutch (not exedy, a genuine one from subaru) + stock flywheel

If you put aftermarket clutch or flywheel or both, it might do the noise, might not.

I have an 05 wrx. Got a Exedy OEM replacement and exedy lightweight flywheel and Boom, I now have this sound.

It comes and goes. Worse in cold weather, better in warmer weather. For a while, the tire pressure trick worked (putting 4-6 less psi in the back vs. the fronts). Now it's just makes the noise.

It's fun having a lightweight flywheel and having spent very little on the clutch. That being said I'll wait a little while and put the OEM flywheel and a subaru factory replacement clutch (not exedy OEM, the Subaru clutch as been re-designed with more sound deadening around the springs and re-located perches)

The sound just drives me nuts and isn't worth the performance gained by the LWFW.
