At my wits end. Clutch shaking first gear. Subaru Forester.

defury · 06-17-2022, 05:47 AM

Car is a JDM 2004 Subaru Forester STI. I had the clutch done at a Poplar tuning shop who is known for building 1000+ HP GTRs and other imports so they know what are doing (or so I think).

I first had the clutch done with a exedy organic OEM+ and a lightened Street flywheel (14lbs) this is where the nightmare starts. I'm very mechanically inclined and immediately noticed the clutch was skipping on the flywheel at the end of the clutch since m stroke in first gear, it hooks up fine at the bite point but as you let the clutch pedal out more in first it would shake harder, shop told me to drive it a bit more to see what happens, if maybe dinner clutch material wore off and it was sticking.

Didn't go away, brought it back for warranty, they told me the pressure plate was shaped a little like a Pringle but I never saw it.

Full clutch assembly and throwout bearing were replaced, flywheel was machined and now I have it back and it's starting to do the same ****ing thing.

I have about 1500km on the clutch and the only way I can make it stop is by slipping the living **** out of it then it's good for a half a drive and starts coming back.

Any thoughts? The shops supplier won't warranty the clutch with a different brand, the shop likely don't comp warranty work a second time I'm assuming, the entire transmission was inspected when apart, no wear on input shaft, no seals leaking into case. I even had them replace the shifter linkage bushings assembly.

The car has had the pitch mount replaced but no other motor/transmission mounts.

I'm at my wits end and ready to drive the car into a ****ing River.

Any suggestions?

Subscribing because I have a similar problem with my WRX..

Can you feel the/a vibration in your clutch pedal?

I think mine is the TOB or the pressure plate because I can feel the vibes..

Yours I have no idea..

If I press my foot down slightly on the clutch pedal I can feel vibration my tob is brand new though

Sounds like we have similar problems..

Something between the clutch fork and crankshaft must have runout..

The only thing I know about my clutch is that their is an exede racing clutch sticker in the car..

Throw out bearing, pressure plate, clutch disk, flywheel..
I figure something must be wobbling somewhere..

Either way the engine has to come out..

My problem is slight enough so far that I can live with it as it is, or until it gets worse..

My clutch is still holding all the power so in that aspect it’s fine..

I have 03 wrx. Mine is doing the same thing since I got the car. I have tried resurfacing flywheel, replacing clutch and flywheel, replacing motor and trans mounts. Nothing worked.

I suspect that master may be tired and slave is also due for replacement.

I am to the point where I think it is the trans. If I grab front axles there is play up and down. I've just decided to get another 5 speed and its matching rear end out of a legacy or something in the junkyard. It will also probably be a push clutch which is fine with me.
