its not lowered is it?

I've just had a golf 1.8t in with a harsh noise that was lowered and it was the ns shaft actually bottoming out in the inner cv casing due to the angle it was running at, made a really load knocking/bumping noise as soon as you turned right even slightly

Mine's picked up a deep descending drone as I pull up to a standstill, whether I'm in gear or not. I went through a 'f**k, it's the diff' moment initially, but I reckon it may actually be the worn wishbone bushes vibrating under braking because you can feel it slightly through the wheel.

My car is lowered. But its been a lot lower in the past with no trouble. One day it was fin then the next it started makin the noise. Had a bearing changed and that sorted one noise out but another appeared

On looking into it there was no play in any cv. And I couldn't hear anything from them, jus fron the gearbox.

Turns out the gearbox was not it hence why I think its the inner cv?

Guess we will find out tomoz lol

Cheers clive, ne probs, still not stripped it all yet.

OK.

today Ive been trying to sort the trouble out as the gearbox was not the problem. (I now have a perfectly good box in the shed) on a side note, the clutch I had taken off was really good, for 93k it look s really new. pics soon.

Back to it, After collecting the car on Monday it seemed ok. went to work yest night and it was there again and got worse and worse. Ended up going in at 50 just in case.

I noticed that the brakes were really bad too.

now when I got home thismorning I set to changing the drive shafts over. OMG what a pain, the tie rod ends were not easy and I ended up cutting them off so ne TT ones are on order along with ne TT ball joints.

One thing on that note, before Xmas I had a bearing go so had it changed at Welsh VW specialists in Barry http://www.welshvw.co.uk/, Well recommended and used once before to sort the brakes and get some info. seemed to know their stuff and I would of been happt to use all the time.

However! while they did the bearing I asked if they could fit my Ball joints. kk all sorted they were on and the initial drone had gone but another had come about between 30 and 40.

while stripping the car today to put the other drive shaft on I noticed this:

IMG00149-20110202-1510.jpg

Now I am no expert but when the ball joints are genuine VAG and they say L and R on them, what T**T puts them on the wrong side?

I wont be using them ever again!

I also noticed that the rear pad on the drivers side had once again come away from the backing, BD predator pads with lots of meat on them are now in the bin. On looking at the back of the disc too it looks like thats the source of the noise, Ill find out tomoz. the disc is really mullered and looks like its been broken for a long time as the lip on it is really big on the inner part.

I have now been up for 29 hr straight and I am calling it a day, I need to collect the parts tomoz first thing and then get home and make up the subframe with a quick rack and Powerflex bush, R32 ARB, TT wishbones and ball joints. and take the arms off my std rack and put them on the quick rack. then put everything back on the car with the discs and pads off the other car. then off to A&A for a laser allign.

One thing tho, Ive looked at the Hub housing from the other car with all the TT bits on and it looks the same as the one on my car, I know Ill need Ball joints from the TT but will the TT tie rod ends and Ball joints go onto the std HUB housing? iirc I read somwhere to have the TT cast bones you need the TT hub? is that tru? Lord I hope not.

cheers

Bringin this up again.

The trouble continues.

After doing the drivers side hub and shaft, that made no diff.

I have just done the hub on the pass side as I thought it was the bearing that may of been fitted wrong by the garage. guess what

no that. its narrowed down to the shaft and the CV's. the one off the other car needs work on it and there is more play in the joints than on mine. Since doing a load of work last week its got worse there is now a vibration and the droning.

I am gonna get my original hubs that are now off the car repressed with ne bearings. or wait to try get some TT hubs? and press the new bearings in to them and put the outer parts the wheels go onto into them too and that should allow me to use the vRS drive shafts?

then the car will be a TT at the front. Ill also fit the brembos too.

I am getting really peed lol, should of left it alone really and not modded it.

Damn Briskoda!!!!!!

:giggle:

my 1.6 has been doing this for at least 6 months now. had the wheel bearings replaced and didn't make a difference. noise sounding like its behind the radio so i suspected the gearbox. changed the oil which was filthy but didn't look like it'd be changed since new (nearly 90k now).

i suspect the gearbox but it also has frequent issues getting into 1st gear (often need to clutch up and down to get it to go smoothly) so i'm thinking the clutch maybe misaligned as the gear change is 3rd world compared to a year newer octavia i drive from time to time (no noise). something in that general area i suspect is at fault.

not really sure whether its worth replacing or repairing. rivets definately a bad idea but its not like the 99hp 1.6 can do that much damage?. its a duu type box if that has any bearing on how badly it was originally built.

anyway would be interested to know if anyone finds anything after having this noise and removing the box prior to destruction.

on a replacement note is it simple as removing the linkage and the drive shafts then unbolting and repeat in reverse or do other things need to come out? i understand one of the mounts is under the battery or in the washer bottle or something.

cheers

It was not the gear box mate, I purchased another car just for the Quaiffe box in it lol and it didnt soort it. I have swapped the drivers drive shaft and hub for the ones off the other car and Ive jsut swapped the pass hub off the other car. I think I damaged the bearing in it tho when removing the ball joint from it coz now the car sounds like it did at the start of all the trouble when I took it in to get the bearing done.

As for this other noise that has not gone, I am now lead to think its the inner CV joint. as according to Haynes you can damage it if you dont support it when you take the hub off. I have a feeling that the mech didnt do that.

I need to order a load of stuff from TPS when they back up and I get a 3 day rest period in 2 weeks so Ill be doing the following.

Prep:

TT hubs (gonna see if there is ne diff in the parts) Get them cleaned up and painted for protection. Press in NEW Genuine bearings

New Splash Guards and bolts

LCR Brembos (IF they arrive? starting to think Ive been ripped off as they should of arrived yest and the JD number for DHL dunt work)Stripped and painted Green to match.

New Nuts n Bolts for all the front suspension.

TO DO:

Remove all drive shafts- Strip the 2 off the other car down and my short one down. Find the best inner and outer CV joints and put them on a short Shaft

Remove Wishbones and hubs-replace the bushes for NEW and refit with the TT hubs

Remove the front Coilovers again and reclean them(NoTE to self: only wax spray the springs and strut, not the hole thing)as it squeeks a bit now.

slightly lower subframe to swap the tie rods for TT ones again. OR just put the NEW tie rod ends Ive just put on on opposite sides? as the TT ones point up but ours point down. however they both seem to fit and have the same taper on them. anyone know different?

So if any of that sorts it out Ill let you know. If not Ill be breaking another Octavia vRS! and looking for another car.

billy

Bloody hell Billy, sounds like you're having some bad car-luck recently!

From my recent front wheel bearing failure, I still recon it could be bearing related. If they cocked up the BJ's that badly, I wonder if they even replaced the bearings! The bearings seem to make a rhythmic rumbling/droning noise, at about 40mph, when they go. I'd expect a driveshaft (CV's) to make a knocking or rattling noise, and a gearbox to make a whining noise.

I've changed the gearbox and transfer box on my Suzuki, so I got used to the sound of transmission death. The transfer box whined loudly for years, until it siezed one day while doing 70mph on the M27! An interesting experience! The forces were so great that the shaft actually exploded out of the side of the casing! Anyway, back on topic.....

This next ones is a bit baffling, This bit here is where the noise is coming from, I have also noticed a leak on the one side. However I got out pritty much what I put in, I have just taken out the old stuff and replaced it with the castrol SMX-S 75w85 which is more of a honey colour.

How come the gearbox oil is getting so dirty?

Drivers side:

IMG00038-20101231-1847.jpg

One last thing, I noticed while under the car was this pipe looked to be leaking? it is the same pipe that winds near the gearbox filler hole. this part is behind the box going down somewhere.

IMG00041-20101231-1849.jpg

Your drivers side output seal looks identical to mine, with that oil stain around it. I'm unsure if it's a leaking rocker cover gasket (oil slowly dripping/seeping down onto the diff housing from above), or if it's the drivers side output flange seal. Both things look easy to replace, so no biggy. Looking at the oily mark, it's only a weeping seal (if it is the output seal), so you won't lose much oil from the gearbox. You can see my near identical photo here: http://briskoda.net/forums/topic/196443-gearbox-output-flange-seals/

That leaking pipe is the high pressure power steering hose, that goes from the pump to the rack. If you think it's leaking, I'd check the fluid level pronto, because if it runs out it'll knacker the pump. My hose blew the other day, at the pump end, which turned out to be quite expensive! The hose is a one-piece item, and costs about £130 new from the dealer/TPS. Luckily you have a donor car, so I suppose you can just swap the other one across. If you do change the hose or top up the level, make sure you use the proper VW rated fluid (it's green), as I've heard the pink stuff (for GM) can damage the pump/rack. Here's my thread with all the details: http://briskoda.net/forums/topic/192247-burst-power-steering-hose-aaargg/page__p__2291151__fromsearch__1#entry2291151

HTH mate, and good luck with curing the noise :yes:

  • Author

cheers Bodge.

I think the pipe was like that from oil dripping off the engine as Id just done an oil change. All seems good now and the level is fine.

I only use OE stuff from TPS ne way mate. only reason I didnt use OE G60 fluid that time was I needed it pronto.

I didnt notice any less oil in the box when I checked it? I think it is fron above. strange tho that it only seems like its that side that goes? good luck sorting it mate.

Ill keep everyone posted on my improvements.

Brakes cam today too lol

they are mahoosive. looks like the 18" TD's will go back on till I get spacers.

Billy did you ever get your noise sorted out?

When the noise first started was it something you could clearly hear or was it more of a dull drone and something you could feel rather than hear directly?

I have a really dull noise on mine which I think is running gear related it is very subtle and not as noisy as something like a wheel bearing. I was hoping it may amoutn into something more so that a mechanic could hear it, but it hasn't.

It is really annoying trying to explain what is it to a mechanic when you know it shouldn't be there and is not normal, but is very subtle.

When my wheel bearing went it was a drone noise. If it goes away when you turn one way but is noisier if you go the other then it's likely to be a wheel bearing.

+ 1 for wheel bearing.

It is kind of a background noise that can sometimes be heard better on a smoother road surface as less noise interference.

  • Author

forgot about this thread

The noise is still there. Its not gone away, I know what you mean tho, Its there but only I can hear it. I just think its a noise I have made up and now cant get out my head.

She has done 10k since I swapped the gearbox over and 7k since it was all put on and its not got worse. Ill leave it I think.

I don't know if I can leave mine like this. I'll sell it if I can't get it sorted as it drives me mental.

I do hope it is a wheel bearing at least it is fixed then although just spent £600 on her to resolve the noise, but didn't.

  • Author

ha,

if its like mine mate, Ive taken things off a quiate car that ran perfect and put it into my car and it still does the same, what year is your car?

the 51 car was nice and silent compared to my 05 car, tbh I think its prob the sound proofing in the older cars was better hence the newer ones being noisier in the cabin.

if its driving you that mad mate, just sell the car coz if not youll end up like me, spending 000's on it and still not sorted.

Ive changed:

Gearbox

Hubs(off the other car then TT hubs with new bearings)

Both drive shafts inc CVs (one side at a time)

Brake discs

brakes (Brembos)

Dog bone mount

Rear beam

also used it as an excuese to do more than needed too lol.

I had a 51 plate and loved it. All it needed, I now realise was a RARB, but the 51 plate died as I aqua-plained it of a soken muddy road through a road sign, a fence and into a field with 3 bulls in it which took great interest in my lunch on the passanger seat as I tried to keep them from venturing out onto the road :no: .

So I got another one after saying how bad these cars are in the wet :D and how much they would understeer.

I had no none of the nigling problems at all with my old one, running an APR map, but this new one 54 plate with a revo has given me all the mentioned problems of wheel bearings, it had already had a turbo replacement when I bought it at 29K miles as me being second owner, it has had, creaking stock ARB bushes, it needed a heliport to resolve an issue with cyclinder 1 as it shot a spark plug, and now recently a cracked manifold. So I understand your pain.

When these cars are sweet they are great wolf's in sheeps clothing and will surprise a few.

I think we've learnt maybe once you've had one that's maybe enough, although as I said I do love mine when it running sweet, so hopefully fingers crossed it is a wheel bearing.

Maybe the noise you hear is something like a manifold blowing either gasket or crack like I had mate that did give a constant drone, buffeting noise \ feeling.

Hi Billy and Briskodian, new member to your "noise club"

Do you still have the droning noise or did you find a way to get rid of it.

I have a Skoda Octavia 2001 1.9 TDI 110 HP with a similar problem.

Started with a slightly droning noise when driving / turning to the left, so I assumed it must be the right wheel bearing which needed replacement.

After replacing it it was still the same. I drove a couple of thousand kilometers, but the noise slightly increase a bit. Finally I decided to replace the right wheel bearing again (Hoped that the first bearing had a problem), at the same time I replaced the ball joint and the outer CV joint. The noise seemed to be better, but when I had the wheel alignment adjusted to the correct position the noise was there again.

Finally I decided to replace the wheel hub and front suspension in the right side, but still the problem remained, still getting slightly worse. The noise is only there when turning into a left curve. It doesn’t make any difference whether the gear are in neutral, or the brakes are activated. My wife can nearly not hear the noise, but I can :-( and it drives me crazy

Right now I am considering to replace the right hand drive shafts inner CV, but I am not that optimistic.

Anybody on this forum who has a good suggestions ?

I will keep you updated in case I succeed to solve the problem

Put a new tyre on that side mate and then see.

My noise is still there and since putting the back wheels to the front its really bad now but because its on coilovers its not spot on ride hights plus they will never wear spot on even so any slight wear differance will show.

I gave up on it and she has now done 16k since and still going. Just wearing the 452s out now and putting up with the drone so I can get the lcr rims refurbed and new tyres.

Just to throw a spanner in it, when I put the spiders on the drone is better too.

Your symptoms say bearing. But if its been done then try the tyres.

You will be amazed at the noise a tyre can make!

Billy

I would go for repacking the drive shaft gaters with grease and see if that reduces or stops noise.

Did for me. My inner drive shaft was almost dry(possibly from a split previous gater). Turning would make the noise worse as will strain the CV joint. :thumbup:

  • Author

my std CVs had really thin oil in not grease. they were the std ones too. these ones now have the grease in them. packed lots in.

I would put money on the tyres too.

For some reason my car seems to wear the inside sholder. even now its raised up. aligned too.

wierd, should never of done anything to it really lol.

Hi

Thanks for your inputs.

Forgot to write that I have already put on new tires, so they are not causing the problem.

Yesterday I tried with another driveshaft, but the noise is still there.

I read another post where the problem was solved by changing the wheel bearing in the left side. As described above I assumed that it should be the right front wheel bearing, because the noise is there when turning to the left. Maybe its worth a try.

Will keep you updated in case i solve the problem.

John, sorry to hear your problem, I have had my noise confirmed by one of the sponsors on here as being present, so I know I am not crazy now, but too subtle to do anything about :-(

That is after I spent a lot of money with them on what they thought the issue was :-(

I since took it to Skoda who said that it was a dodgy wheel, so we replaced that wheel with the spare, but not sure it made a huge difference, so it is now down to getting that bearing done which I have not had time to do. My dodgy wheel was on the rear, so the directional thing was hard to establish with mine as it didn't really make that much difference as it never really got much louder.

Once I have done the rear bearing I'll let you know.
