Noisy Thrust Bearings

Does anyone know if these can be lubricated (without removing the gearbox)? Mine are making a little bit of noise. When I touch the clutch pedal they stop. Clutch is in perfect condition too. I know some cars have a special panel to look at the condition of the bearings and to grease them. Is there one of these on an R33?

Mine just do the 'sshhhh' worn sound when clutch is out. no squeaking, i have heard u can lube them but the noise comes back very quickly, so it's not worth it, most people wait till they need a new clutch to replace the thrust bearings but since you've just got a new clutch you might want to remove that gearbox again? :D

I think I'll just have to leave 'em, I don't want to spend big $$$ on labour for a small job like greasing some bearings.

if it really bug's you. take a can of wd40 and a NARROW hose. modyfy the hose to fit the can then remowe the rubber protector on the gearbox housing and spray the MF thrust bearing.

OR better get a really FAT exhaust 3,5'+ with only one damper and yo' probz will desapear... :)

No offence dude, but this is the worst thing that you could do.

WD40 will wash all the grease out of the thrust bearing, and within a few days/week the bearing will be running dry !! the first few days it will be quiet, but after that..... :) Not a good thing.

The only way to fix it is to drop the box and repack, or even better, get a new thrust bearing. :(

just a tip. losen the engine bushings/mounts some turns and lean the engine down in tha back when you mount it back cus' it makes the job A LOT easier.

Apparently noisy throwout bearings are a VERY common problem on Skylines. I've heard of people going through four or five bearings before they found a quiet one... but then again, all it is is a noise, it's certainly not an indication that your gearbox is about to seize!

From experience, don't bother trying to 'repair' a bearing unless it's an emergency - a repacked/lubed bearing is certainly better than a stuffed one, and it's better than being stuck in the middle of nowhere, but you cannot guarantee how long it will last for. A day? A week? A year? Who knows - you can't rely on it, replace it with a new one ASAP. If it's just normal bearing noise (rather than a noise indicating bearing failure, eg rumble or screeching (!) ) leave it alone.

The squeaky clutch pedal is quite often just the plastic bush on the pedal pivot. Just spray it with some decent lube (that won't eat the plastic) and push the pedal a few times. If that doesn't work, lube the actuator under the car (where the clutch fork comes out of the bellhousing). Easiest thing to do is to get under the car and have someone repeatedly press the pedal, and you just sit there and lube anything that makes noise - within reason of course :)

      I had never actually looked into it, but aren't onboard compressors a thing in trucks?

      Anyone have this problem with their temperature gauge?

      Read the ECU for fault codes or have someone else do it. A faulty coolant temperature sender is usually listed in ECUs. If the sensor itself is not busted it can also be a bad ground connection. Or in a really unlucky case, damaged wiring.

      Anyone know this frontpipe?

      Can't be a Futjitsubo as those are made with a flex piece and Reimax is smaller in pipe diameter. If anything it is closest to a Mines pipe, but evidently it is not an actual Mines pipe.   Classic word humor

      Alright I will try to not forget.   As GTSboy replied to you already, problem is mainly the mismatch between the actual exhaust part and the denomination in the papers. That basically just looks like tampering to a cop, if they were to check your car and notice. If it had been done right they would have clarified it to be a custom pipe and just given it a certain part number that you have to engrave or weld onto the pipe. I will definitely inquire on what to do. Changing the pipe wouldn't be my favorite solution as it costs a bunch of money and the cat was fitted with the front pipe and exhaust under the car, and if the front pipe flange does not sit in the OEM location the cat will need to be refit for any other pipe to work. It also usually doesn't need a brand name or something like that, but more something like a part number. Usually for exhaust parts, on silencers and cat units specifically, there is a badge that reads the certificate number that belongs to these exhaust parts under EU regulation. You get these numbers after you put a part or group of parts through the tedious testing according to EU vehicle legislation and they pass. You can find these "part numbers" on various parts throughout a EU vehicle. On windows, headlights, engine parts, seat belts and so on. All these parts have gone through standardized testing and acquired a so called ECE or EG Certificate that makes them legal to use by themselves in all countries that adhere to these standards. You can also not alter these parts in any way, if you do they become illegal. An example for stampings on an exterior lighting part, the people who need to know can find the documentation for this unit in a database. I do not know what all the standards and so on mean.
