Something Screeeeeching!

[Robbo VS3]

There is a god awful screeching/squeeling sound coming from my VS. I assumed it was the drive belts, but i had them replaced just last week. The screeching continues and i don't know what it could be, its hard to tell where its coming from, it sort of sounds like it is coming from the engine bay, but it could be underneath. It only seems to do it when im moving. Its loud and people are looking at me funny when i drive down the street. Please help! Any ideas?

Cheers guys.

is the noise worse under load?

did you tension the belts correctly?

[Pie-VK]

Brakes maybe?

Other than that i'd check your belts and see if they're tensioned properly like Nemisis said.

[Robbo VS3]

The noise is not worse under load, i don't carry much weight. I did'nt put the belts on, the auto place did it when i was getting it serviced, but the noise was there before the new belts were put on.
I said to the guy, there is this loud screeching noise, and he said yeah its probably just worn belts, anyway he chucked the new ones on and the noise is still there and now its actually getting worse.
I don't think its breaks, i don't touch the break pedal at all when its happening. I had new break calipers and pads put in just a few months back. I tell you this , i get the shits with these bloody old vehicles, always problems and costing money. Have spent nearly $2500 in the last 6 months! I would rather try and fix this prob myself rather than pay someone $300 to do it for me, but i just don't know what it is.

[nemesis_adrasteia]

is it a 6 or an 8?

does the noise change with clutch operation?

you had new calipers and pads but not new rotors?

[vl_nick]

my money is on a worn out idler pulley, remove the belts and spin each pulley to check for worn bearings

[HoldenManDan]

Mate you could try looking at the pulleys individually? Take the belt off and give each pulley a spin to see if the bearings in them are stuffed. Stuffed pulleys might still spin fine, but can also make a noise. Take the pulleys off and shake them too, if it sounds like the bearings are rattling around then theyre buggered.

Just a thought...

[Robbo VS3]

Good suggestions fella's. Nemesis it is a 6, it does'nt change with clutch operation. Rotors? Possibly. Hey Nick and Dan, worn bearings is highly possible. I'll look into it. Thanks men.

ok, i think these guys are on the right track with the tensioner pulley.

may also be that your water pump bearings have let go, the aircon pulley may have seized,


check the tensioner pulley make sure it spins freely and doesnt make any bad noises, check your tensioner arm for tension, also check the belt for signs of slippage

Alright, i went for a drive this morning and noticed a couple of key things. The noise slows down as the vehicle slows down. And when i reach high speeds the noise stops, and after i have been driving for a while and the engine is warm it does'nt make the noise, it seems it only happens when its cold???

does it slow down with vehicle speed or engine speed?

[Robbo VS3]

Seems to be vehicle speed. I just watched a few youtube vids on shot bearings and im nearly certain thats not the problem, bearings make a grinding/rattling noise, my problem is high pitch squeeling.

[Pie-VK]

Hmmm. I had this bad squeeling when I put my alternator brushes/reglulator in wrong and they were angled and only held in by one screw.

I doubt it would be that.

Does it squeel more or less when you turn the steering wheel? Does it shudder?

Could also be low oil maybe? would explain why the screech disappears when the engine is hot.

[Robbo VS3]

Does'nt make any difference when i turn the steering wheel. But you have just given me a thought, i did notice my steering wheel shuddering quite badly the other day when i got up to around 100km. Maybe it is wheel bearings, so maybe the whining and the shuddering are linked.
Just found this vid on youtube and the guy said the noise turned out to be wheel bearings. The screeching in mine is'nt quite as high pitched as his but the noise is identical. At 0:28 when he slows down the noise slows down, thats what mine does.

YouTube - drivetrain whine???

You sure its not the missus sitting in the passenger seat?
Mine seems to do it all the time

yeh i realized mine was faulty when i stopped and got out of the car and the noise was still there

Good suggestion but i don't think its her, i maintain her pretty well, oiled and nipples greased on a daily basis.
Seriously though its sounding like it could be wheel bearings to me, might have to run back to the mechanic. I just tried to catch the noise on film as i was driving down to subway, and it hardley made a noise!! Unbelievable!!
