Ralphch97 Posted October 4, 2015 Report Share Posted October 4, 2015 Hello, so about 3 weeks ago my sport was making a nasty noise, sounded like clutch release bearing as was vibrating a little through pedal and the noise went while the clutch was in.Yesterday (Saturday 4th) I changed my clutch & clutch release bearing & changed the gearbox oil (the old gearbox oil looked quite clean which I was expecting it to look horrible)After changing the clutch and release bearing and oil the noise is still there, and goes when I put my foot on the clutch, I can't really hear it when driving and it doesn't seem to get louder as I go up the revs like my last LUPO when the gearbox was shagged.The noise sounds exactly like a bad clutch release bearing but maybe a tad louder and depending on how fast I let the clutch out the noise of it differs, in neutral if I let the clutch out slow the noise is quiet, let the clutch out fast and the noise is loud!The LUPO is a 1.4 16V sport (The box is defiantly a sport one in the car as the ratios are short!Does anyone have any ideas?Thanks - Ralph!

Sausage Posted October 4, 2015 Report Share Posted October 4, 2015 (edited) Does it have a dual mass flywheel? Do any lupos have them i dont know? if the noise increases in line with engine revs in neutral then it's rotational. I'd confirm that 1st.It's probably worth a quick look at the old clutch for signs of mechanical contact damage. It could be a really shagged pilot bearing, but they usually are noisy with the pedal down.Is there a return spring on the clutch arm on top the gearbox?

Ralphch97 Posted October 4, 2015 Author Report Share Posted October 4, 2015 (edited) Flywheel isn't a dual mass one, and I couldn't tell you, as far as I know Lupo's don't have them, I know mine doesn't! Haha!Im 99% sure it doesn't as I can't hear it while increasing the revs, I think I'm going to have to take the box out again and take it to a specialist! ?Do you think I'll be okay to drive it, went to Sheffield (110 Miles) on it last week which was probably a silly idea! But gearbox is slick and very smooth!It's just the noise! ?And the old clutch looks okay, just normal wear!Thanks for getting back to me!And I'll check with mate about clutch Spring he helped me/did most of it!

Ralphch97 Posted October 4, 2015 Author Report Share Posted October 4, 2015 Looking at it the is a return Spring! Quote Link to comment Share on other sites More sharing options...
Sausage Posted October 4, 2015 Report Share Posted October 4, 2015 (edited) At what point does the noise go when pressing the clutch pedal? experiment a bit and see.it doesnt increase with revs in neutral you say? or does it?The 3 likely suspects are release bearing (you did actually change it? LOL) pilot bearing (quite rare) and input shaft bearings on gearbox, which given it's an 085 box seems quite likely, though the weakest and most prone bearing is on the output shaft and wouldnt make any noise unless you are driving it.

Ralphch97 Posted October 4, 2015 Author Report Share Posted October 4, 2015 It goes as soon as you hit the biting point on the clutch, when i let the clutch out fast the noise is louder than if i let the clutch out very slow, & i drove the car earlier and im starting to hear a noise now while driving, mostly when i let off the gas pedal in gear the transmission makes a whining sound, not quite a whining sound but cant describe it any other way, then in neutral now i have noticed if i rev it the noise increases i can hear the noise up to 12000 rpm then the engine sound takes over it, but its defiantly not a healthy sound.And yes, changed the clutch release bearing, old one didn't even look to bad and when i drained gearbox oil looked clean, had the car 3K Miles starting to think they changed the oil and put an additive in to quiet down the noise as when i purchased the car sounded healthy and smooth.

Sausage Posted October 5, 2015 Report Share Posted October 5, 2015 (edited) Gearbox bearings then mate, sorry.Yeah, avoid driving that hard if you want to save the gearbox and rebuild it. You can stooge about in it now but you have to listen carefully to what it's telling you.You could always put some thick oil in there to shut it up a bit if it's just starting to whine, but that's just masking the problem and possibly had already been done.I should also learn to read LOL, i just reread your OP and saw this seemingly for the 1st time (sorry): "in neutral if I let the clutch out slow the noise is quiet, let the clutch out fast and the noise is loud!" Yeah, that's saying input shaft bearings right there. Edited October 5, 2015 by Sausage Quote Link to comment Share on other sites More sharing options...
Ralphch97 Posted October 5, 2015 Author Report Share Posted October 5, 2015 Thanks for help, I'm taking it to get rebuilt at a local gearbox place, Bit annoying as I have to take the box out again! ?They offer a 12 months warranty so I'll have feedback if anything gives up in it again!They are doing a free strip and Quote so that's good!Does anyway have an idea of how much I could be paying, or how much I should pay up to!

Sausage Posted October 6, 2015 Report Share Posted October 6, 2015 (edited) Does the free strip and quote include a free putting it back together again if you decide to not use their services because they are too expensive? Or do they leave it in bits and expect you to take it as is?If they have done these boxes before they should be able to quote over the phone for a simple rebuild assuming it's just bearings and seals without opening it. That should give you a figure to go from. The full bearing and seal kits seem about £100 mark, there's some rebuild ads on ebay that will give you a figure too.

Ralphch97 Posted October 6, 2015 Author Report Share Posted October 6, 2015 (edited) I didn't ask, but I phoned them today and they said if it's just bearings it will cost 340 pound! ?Hmmmm!Another quote - 295 pounds, but warranty only covers bearing and seals where as the other one covers everything!Or - A recon box, comes with 12 months unlimited miles warranty - 385 pounds!

Ralphch97 Posted October 19, 2015 Author Report Share Posted October 19, 2015 Please can someone help,So I have changed clutch and release bearing, had the gearbox reconditioned, and changed clutch cable, yet the noise still occurs, exactly the same just a little less quieter,The car drives great so I'm beginning to think it's just the car, it's just bugging me, had the gearbox reconditioned and clutch done and bearing yet it still occurs, does anyone else's do this! If it does do it to other people I'll forget about it but it's seriously annoying me now, 500 pound later and still there!Please help!

Sausage Posted October 20, 2015 Report Share Posted October 20, 2015 (edited) Assuming the noise is the same noise on the clutch pedal, you are at the mercy of the gearbox rebuild there. Have you driven or been in other lupos to know how much yours is different? I assume it was significant for you to go to the trouble of changing release bearing and clutch to start with. Now it's the same noise just quieter right? Edited October 20, 2015 by Sausage Quote Link to comment Share on other sites More sharing options...
Rich Posted October 20, 2015 Report Share Posted October 20, 2015 jack up the front, disconnect the shafts then see if the noise is still there. Quote Link to comment Share on other sites More sharing options...
Ralphch97 Posted October 21, 2015 Author Report Share Posted October 21, 2015 It shouldn't still be the gearbox as it had all the bearings rebuilt, the noise only really occurs when it's warm, and sometimes is quiet and sometimes is loud, and I have driven a polo and my gearbox is a lot smoother just doesn't do the noise mine makes on idle in neutral, could it just be gearbox chatter?I'm lost, surely if it was wheel bearing it would do the noise all the time? But I'll try what you said! Thanks!It's annoying me, then again at work today my colleague has a 13 plate Mitsubishi l200 (completely different cars I know) and his car makes a slight noise when the clutch is out and it's warm, and his is on 13,000 miles so could it just be where the gearbox has no pressure applied hence why the noise stops when clutch is pressed, sorry if I'm talking aloud of gobble!

Sausage Posted October 21, 2015 Report Share Posted October 21, 2015 You need to get some opinions with someone actually listening to it. Take it to a couple of independent VW garages or similar and see what they say about it. Quote Link to comment Share on other sites More sharing options...
