Whining, not the wife, mother in law, dog......

How you fellows can even attempt to help diagnose a whiningg problem from all the threads that cropped up in a search, is a complete enigma to me. Yep, amongst a plethora of other things, I've got this whine. It's constant and increases/decreases with road speed not engine revs. I fitted a set of "upgraded" discs and pads with perforations and grooves. I'm hoping that my limited diagnostics ability can see that these would be like spinning pan pipes. All the calipers etc. were renewed at the same time so, there are no sticking pads, I'm certain. Please tell me that that's all it is. Universal joints are also mentioned a lot in my search results. I'm wondering what would whine about them. In the olden days if one went it clonked and rattled like hell, no whine. Coincidentally, on my early test runs, I've been getting a clonking/clattering sound. I thought I might have not tightened the new shockers properly or the rubbers had compressed. I had one years ago where the upper bolt had worked loose. I've found no logical diagnostic procedure to go about in this scenario. Driving, listening and looking under the motor would present, even to you guys, somewhat of a challenge. Is there such a thing as a gospel of whine testing (go on, cheese and bread and good company) in existance, maybe even a sticky I've failed to turn up? Best regards, once more. Peter.

As you have ruled out Mother, dog, wife , is there any chance it might be you. I have been close to tears with mine,so maybe whining is just part of the experience?



Sorry I can't help

Did this whining only start after you changed the brake disks then?

wheel bearings diff gearbox transfer box

Wheel bearing constant and changes with road speed also changes pitch when cornering. Diff pinion only constant if really bad. If just starting to wear goes away on acceleration but returns on overrun.

I know I've posted a daft question. How can anyone diagnose a sound that can't be heard? I've got to start somewhere and you're it. I'll just start with the wheel bearings. If that's wammer's starting point, then it's mine. I take it that universal joints are ruled out. If you could see the carers in here and taste the food, whining would be an olympic event. I can't remember if the sound was coincidental with changing the discs or not. You'll all get like this. I wondered if any kind of sound was typical with these things.

Nothing is ruled out, but a wheel bearing is distinctive as is a diff pinion bearing. Diagnosis of a sound that can't be heard is a little difficult. Unless you are deaf in that case get someone who is not to listen for it. Best way would be to put it on a ramp block the wheels up and run it in gear. Then go round with a stethoscope. Problem with live axles is a bearing noise is transmitted along it so finding the loudest point is the key. That's why you need a stethoscope.

Why did you fit drilled and slotted discs are you thinking of using it on track days?

Have you stuck your head under the bonnet yet to rule out water pump or alternator bearings, or does the noise only occur when the vehicle is moving?

He says it's not subject to engine RPM but road speed. So that would kind of rule those things out.

Now, that's shook a six for me.The starting point I was looking for. Thanks again. With no ground contact are the wheels and axles still going to go round. If you're suggesting it then I guess so. I also guess that the traction control won't throw a wobbly. My discs and pads needed changing so when I saw "upgraded" I thought I might as well go for them. I pull a hefty caravan with this thing which tends to drift on the corners at track days. Any extra control, I thought, would be a plus. The hot hatches waft us all over the place as we overtake. Head under the bonnet? I thought that was the position of choice. I've yet to graduate to sitting in the cab and driving it. I suspected the alternator straight away as I was stuck in the south of spain with mine being wiped out by a fuse box meltdown. I could only get a scrapper in the time I had. I changed the serpentine belt at the time and was careful to check the dreaded idler and tensioner. As far as not hearing a sound that can't be heard is concerned, I'm ideally situated. We're all deaf in here.

Have you checked there is oil in the diffs,sometimes the simplest things

Funnily enough that's rung a bell. Years ago, come to think of it, I did get a whining from what I thought was the front axle. I posted on here as a matter of fact. It seemed to disappear when towing. I subsequently drained the axles and everything else come to that. I've learned about "it's had a full service, sir" when buying. What came out looked like one of matron's wrung out poultices. I renewed all oils all round and the noise hasn't bothered me since. Just how long the time gap is between getting the whine and noticing it I can't say. I'll hold my hand up here. I buy my oils from ebay in 25ltr batches, anti freeze and all. Is this accepted practice or, is oil is oil perhaps not the case? To actually answer the question. Yes, I've only just gone through the whole lot but thanks for the constructive observation. Regs.

Turn the radio up.

You're assuming my radio works. I've double listened to my alternator which I bought from you know where. Screwdriver to ear. Noisy as suggested. A good step one. Mine is Bosch ERR5834 150amp. Wildly expensive from everywhere. There are places quoting much lesser prices for ERR6413 that they claim supercedes ERR5834. I'm talking hundreds different. Am I to believe this?

I don't know what just happened. I clicked on your quoted link and the transaction I made this morning came up. I double checked with these people on both part number and secondary number. I've ordered the idler pulley and the tensioner this morning. I'm not sure the row I referred to comes from around there but I double checked as suggested here. I wish I knew everything from birth.

I clicked on the link and it came up immediately, however, it says in beg red letters DOESN'T POST TO UNITED KINGDOM

That is one thing about ebay that REALLY gets my goat (see my post Which Supplier, you'll see my rant about couriers...they're all bastards even more so when you order a brand new TV and they boot print on the smashed screen matches a Dickies Donegal size 9 steel toe capped work boot Like I said, they're all bastards)

Anyway, my 38 been whining like a blonde ever since I put her on the road I bought a new idler pulley and a belt, but 8k miles later I still haven't fitted either and she's still whining like some wannabe starlet

Fit the idler pulley & belt, mine was whining for a long time & was convinced it was alternator so refurbed & still there, turned out to be idler pulley in the end.

Did he belt in Spain. My transaction on you know where came up, probably, on account of what's in the cache on my Moby. The item is coming PDP. I know the driver. But do I ever agree that couriers have you over a barrel. Especially if the wheels fall off a delivery. You might as well howl at the moon. Try depending on deliveries when you've conked out in Spain. What a laugh that is. Thanks for the tip off on the likely whining culprits. I'd have put money on it not being in that department. I'll report back. Matron made me use her ear trumpet. Worked great but I'm back in therapy because it got wrapped up in the serpentine belt along with my necktie.
