Gearbox Gearbox & Clutch Discussion

If the noise disappears when you press the clutch pedal then it sounds like the gearbox input shaft bearing is failing. When in neutral with the clutch engaged the input shaft is spinning in time with the engine, depressing the pedal disengages the shaft from the engine. Not particularly good news I'm afraid.

I'm worried: in neutral I hear a noise, when I downshift and at constant speed I hear a whistle.. I don't know what to think.
 
Hi Jajodu, Thanks for your help. As for the noise in neutral, I agree it's the release bearing. But the whistling noise when downshifting when and at constant speed, I think it's the clutch not the bearing, what do you think?
 
Unlikely to be the clutch the way you have described the problem in my opinion. The noise in neutral goes away when you depress the clutch pedal? Correct? In that case it's more likely to be the gearbox input shaft bearing as I explained previously.

When I press the clutch in neutral the noise disappears; I agree with you that it's the bearing. I hope that by changing it, the whistles in downshift will also disappear.
 
Hi everybody.

I've been reading all the comments, and the last ones, confirm what my car does lately, but it does another thing: when in neutral and I accelerate between 2000/2500rpm, the car shakes.

Could this be provoked also by the input shaft bearing or the dual mass flywheel?

Thanks in advance.

Hi!

I'm talking about my I30 PD/PDE 2019 1.4 T-GDI.
I know it's an N forum, but here have problems with non-N models.

Thank you for your reply.

Hi again!

I can't edit what I've written.
"I know it's an N forum, but here also have problems that non-N models have."

Thanks in advance.
 
Theres nothing that crosses over in the drivetrain from the i30N to the 1.4T engine. It could be a number of things related to the clutch or transmission.👍🇺🇸
 
Would really appreciate some input from anyone else because I'm not sure if this is anything. Recently I noticed when engaging the clutch, when driving around at lets say around 40mph (it could happen at all speeds/gears but haven't gone and tested it out), around the biting point the clutch pedal vibrates a bit. I can't for the life of me remember if this has always happened and is normal or if it's new. It's just really bugging me not knowing.

Talking in regards to an i30N pre-fl if that helps

Thanks in advance
 
As the clutch is hydraulic it won't be from the slave cylinder or pressure plate. It's more likely to be engine vibration.
 
Not having heard nor felt the vibrations I'm only guessing. If it's just a feeling rather than a definite problem you are probably worrying unnecessarily.

Completely understand. Thanks for the help anyways. I’ll put this down to just coincidence that I didn’t notice it before and keep and eye on it.
