Chirping/ Squeaking Sound On Clutch, Possible Fix?

I've recently bought a GTS25T and everytime I start the car, I can hear a constant chirping sound when the clutch is not pressed. As soon as I even touch the clutch pedal, the noise stops completely.

My mechanic has told me over the phone that it's either the throwout bearing ($800+ to fix) or the transmission (over a grand to fix).

However it's not a big sound at all, and doesn't seem like it could damage anything. It can't be the throwout bearing, because the characteristic of a worn throwout bearing is loud chirping when the clutch is pressed, not released.

So I've googled and googled, and this seems to be the most cost-effective solution, it makes sense but I just want some acknowledgement before I go and try this procedure:

"To fix the squeeling; chirping; or whirring sound that goes away as soon as you apply even the slightest pressure on the pedal. You need to replace the lubrication that has dried up at the point of the shift fork and pivot ball stud. The loss of lube has allowed it to dry up and the noise you hear is actually a frequency vibration and as soon as you put pressure on the pedal it dampens the frequency, and the noise disappears. To replace the lube do the following:

Get a can of disc brake wheel bearing grease and a small stiff brush, like an 'acid brush'

Pull the shift fork boot away from the bell housing

Push the shift fork forward, towards the front of the car. This will be difficult, but you can do it. It will probably look dry and rusty in the area of the contact of the ball stud

Now, while holding the fork forward, take the brush that has been loaded with a dab of grease, and smooth the grease around the area of the ball stud and shift fork dimple. Do this 2 or 3 times.

Replace your shift fork boot, if so equipped.

You will have eliminated the noise. As soon as you start up the engine, the noise will be gone."

What do you guys think?

i dont know about a chirping sound but i got a grinding sound when my thrust bearing was worn. $800 is over the top just to replace a thrust bearing you can get a new HD clutch + labour for that price and that includes replacing the thrust bearing too.

i got a new clutch and bearings replaced about a month ago along with a nismo pivot ball, got rid of the grinding noise but a week or so ago i think its come back again. annoying considering i got everything replaced.

interesting thought about re-greasing your pivot ball joint. would like to know if that works.

I'm all thumbs when it comes to mechanical repairs. I know it's easy to do, but I don't know where this pivot joint is, and I don't want to f it up! But it doesn't come across as serious, just annoying!

Yeah I thought $800+ for a bearing was a bit excessive too, I almost had a heart attack because they said that they had to take the whole transmission and gearbox apart. Sounds like a major job!

      R34 GTT AC short cycling ? Normal behaviour?

      By George. · Posted

      Hey guys, Just want some advice on r34 GTT ac system. Since I’ve owned it, the ac compressor, doesn’t matter the set temperature or ambient temperature, runs for around 10 seconds then disengages the clutch, then re-engages everywhere 30 seconds or so and keeps repeating this.    is this normal?   I had it recharged today as it was slightly low and thought it would fix it but still does it. it cools fine in summer even prior to the recharge, except for the usual warmup when stopped or in traffic (still yet to wire overheat fan to on with ac)   any thoughts would be much appreciated

      Factory oil temp sensor in a RS4V without gauges?

      By GTSBoy · Posted

      To plug the hole. The engine plant may not have known whether the car it was going into had a gauge or not. It was a long time ago and the integrations might not have been fully modern. Or they might not have cared because the extra inventory and processes to save a few cents on the sender might have cost more anyway. But please tell me you are not still confusing the idea of a pressure gauge sender, and an oil pressure light switch. The switch will be out there. In a separate hole. Probably with only one wire running to it. Running the light.

      Blower needs to go low on the exhaust side, displacing the AC and PS, which you have to decide whether you want to keep and how and where to relocate if you do. Electric option for PS is, at least, helpful. Sadly, there is no workable 12V electric AC of any value. Whilst the blower is the last compression step before the throttle, and so it might seem a good idea to have it near the inlet manifold (as mentioned above), you probably want it to go through an intercooler first, so, having it on the opposite side of the car facilitates that air flow path. The turbo discharges into the blower, so proximity of the turbo's compressor outlet to the blower's inlet is nice. But then you might want to intercool that too, before boosting it again....which would probably be a ball ache. Routing pipes out to the front and back could be a bit shit. If there was room for (at least) a small (but preferably larger) water to air core on that side, then that would probably be the best approach. I guess a reasonable alternative would be to locate the blower where the alternator is (more or less, associated with the inlet manifold, per Matt's thought), and somehow incorporate a water to air core into the manifold, sort of like they do for modern blown V8s. The big difference here though is that those V8s have only the one throttle (upstream the blower) and only the one compression step (the blower) and no need for too much in the way of bypass/blowoff valves. Whereas in a twin charged 6, you do need to think about one or two bypass valves associated with the 2 compressors and you would prefer to have the intercooling done before the air has to pass through the throttle. You'd like the throttle to work approx the same no matter what the compression is doing. But if it is located in hot air stream before a cooler, then sometimes the air will be real hot, sometimes it will be quite cool, and the throttle mapping/response will be quite different between those two cases. The throttle, if sized for hot air, would be too large for cold conditions. It's all a ball ache.

      Package SC on exhaust side. Remote mount turbo. Still a fair bit of room when you get creative on the inlet side of the motor too. Especially if you can get really creative with the welding, and effectively build it into the bottom of the inlet manifold. Would definitely take some design work, and some trial and error, to make sure flow works well still! Might be easier to just start with the Nissan March though... All the work is already done for you...
