SOA didn't fix my clutch-shudder problem!

"The fact is that the relatively hard lining of the clutch disk gives the car such incredible clutch wear mileage is prone to a slight chatter condition when cold. This sensation is make more noticeable by the five drive shafts in the car. Their relatively light inertia make them prone to 'ringing' in response to the cold clutch chatter. This usually goes away in the first few minutes of driving. This is a normal characteristic of the car. It can be made more noticeable at some point in time due to heat damage from excessive slippage of the clutch.
If a driver (does) not drive a manual transmission car smoothly, i.e. makes hard clutch launches from a standing start and/or causes gross slipping power on shifts, then it is possible to overheat the clutch lining, flywheel face and pressure plate. This is true of any car. This can cause damage to the clutch plate lining, altering its friction properties, can cause local damage 'hot spots' to the fly wheel and/or can cause the metal ring of the pressure plate to warp, at which point the clutch may grab on take up or have vibration at all times. It would not be a manufacturing defect, rather abnormal wear and too high heat conditions that have created the situation.
This is strictly the driver's responsibility."
The above quote references long clutch life, but I think there is some evidence that Subaru clutches aren't especially long life units.

I left the car over night so they could reproduce the problem as it was only shuddering when the car was cold (this has since changed). The next morning they were able to reproduce the shudder problem and they contacted Subaru for advice. Subaru told the mechanic to slip/burn the clutch for 3 or 4 seconds with the brakes on. This, so they claimed, was to smooth out the clutch plate surfaces. I was pretty pissed off when I found out 1) that's all subaru told them to do, and 2) they did it (without asking me!).
So, they say not to burn the clutch due to damage it could cause, as that's true of any clutch, yet that's exactly what they had the mechanic do?
I love the car, but this sucks (leaving out explicit vocabulary). It now shudders regardless of temperature (this is months later). I was in 87 degree weather the other day and it was the worst it's ever been.
Looks like it's time to print out the post and mail it to subaru again...

So given that it took 8k or so to show up we'll see what happens.

why doesn't some on try replacing the clutch with a non oem one and also replace the flywheel again with a non oem one.

I agree that the clutch vibrates way too much to be normal. I've driven hondas, mazdas, toyotas, land rovers, even merc benz, all manuals (okay, so the land rover and mb were military vehicles). The passenger cars have never vibrated like this (the military vehicles, well, they were poorly maintained so let's not even go there).
However I do think that it is possible to adapt your driving style to the clutch - I've done so to some extent myself. My car still shudders, but a whole lot less than when I first got it. Sometimes I can even go days without any shudder. For those of us who already own subes with shuddering clutches, I'd suggest we try to adapt our driving style, while we continue complaining to SOA. That way we hopefully minimize clutch wear on our present clutches, and sometime down the road SOA will relent and issue a recall.
I'm relieved to note that someone out there at least has gone over 100k miles in his OB without changing the clutch. Maybe there's hope for me and my new clutch.
Oh, and I'm probably going to put in a Kart Boys shifter instead of the OEM one. I find the current shifter a little too vague for me, and sticky at times. Some other people on this forum have said that's probably due to the tranny fluid though. Anyone out there have any comments? Thanks.

That was just a thought, and does not tie in to the fact that many of you have this problem in the cold. I can report that i have had no abnormalities with my clutch in the cold.
I currently have my tranny out, getting a syncro replaced. I checked my clutch, and it needs to be replaced. After reading this thread, i am very turned off to getting a clutch from subaru. The only problem is i cannot afford a $400 aftermarket clutch at this point. Does anyone know of anything better, or is every basic clutch for the car the same?

The boxer's cylinders fire in pairs.
Is this correct? I thought one cylinder was firing while the other was on the exhaust stroke. That would make more sense to me.

I've tried just about everything to smooth out the starts when it's being cranky (more gas, less gas, slipping the clutch, cussing at it, loving it) and when it's shuddering, NOTHING seems to calm it down. When the car is behaving normally, it shifts beautifully and seems to have an excellent drivetrain...but when the clutch does not want to play, there's no way around it that I have found. When I feel it starting to shudder on takeoff, I've started to slip the clutch through about 3K rpms before shifting into 2nd...it seems to help a bit.
I've tried to short shift it into second (at like 2K rpms) but then the clutch shudders as I go into second so I usually just keep my foot on the clutch through first gear. After 33000 miles of frustration, I think I've tried just about everything, to no avail.
Sometime when I have an extra $600 burning a hole in my pocket (read: not anytime soon) I'll put a new clutch from Cobb Tuning in and see if it solves this mess. I sure as hell won't be spending my own $$ on a Subaru clutch...I don't feel like playing Russian Roulette with another one of their parts.

Yes, but No.
The plugs do fire in pairs, but one is always finishing it's exh stroke, so there is no combustion there. Just as an I-4, there is a fire every 1/2 revolution.

reading your latest post, I'd be inclined to agree with you then, it probably has something to do with parts rather than driving style. I was watching my tacho on my way to school today, scrutinizing every shift. I normally shift between 2 - 2.5K, and there's no abnormal shudder. It's true that there's a lot of low end power in the 2.5 engine; I never let the clutch go completely when I'm backing out of the garage because I'm afraid I'll hit the wall behind me!
And thinking about it now, the shudder for me was worst with the old clutch, which eventually had to be replaced because it was just worn out. Best of luck with SOA, I'll be cheering for you.

Best clutches that I ever used, abused, or just flogged the livin' snot out of. :rollin: If my left leg wasn't wasted and I could still drive a stick, I wouldn't drive with anything else. A little pricey, but I found them to be worth every dollar. :smokin:

I am quite sure it has nothing to do with my driving style (I know, I know...EVERYBODY'S a good driver!) because the problem is so intermittant. When it starts shuddering, I've pulled over and tried just about every possible launching technique (little gas, lotsa gas, slow clutch, fast clutch...) and nothing gets me around the horrible shudder. 20 minutes later, it can be shifting like a dream.
An aftermarket clutch is in my future, I just don't know when I'll have the "extra" $600 laying around.

My '01 OBS 5sp just died in the middle of a busy, dangerous intersection during a particularily bad clutch shudder event. Just about got killed.
My dealer replaced this clutch once. It was OK for about 3K miles then it returned worse than ever.
Dealer told me that SOA said to them that replacing the clutch may have made the clutch problem worse! At any rate they said that was all they could do for me.
It was originally mostly related to cooler weather but now it's doing it all summer long.
I think it's a big safety issue and I sure wish SOA would act accordingly. It's otherwise a great car, but it's tough to remember that when you're hanging on to a bucking bronco

Feel free to email me anytime and I will help you with the process of getting a new clutch.

Just wanted to add another virtual vote of solidarity.

Visiting my folks recently I drove their Toyota truck which got a new clutch about 4 years ago and MAN what a difference. It was a new disc and plate with flywheel remachined. Can't wait to have mine redone, just have to find a money tree and start growing it
