Whining noise .. vague .. need help diagnosing
Going to sound like a bit of a numptie here but looking for some advice diagnosing (or ruling out) a whining noise on my MY00.
It almost sounds like transmission noise, is speed dependant i.e. gets higher pitched the quicker you go and is most noticeable when cold and at about
2.5K to 3K in 3rd. Not very noticable or loud but it's my car and I know it wasn't there a couple of months ago.
Any tests I can carry out i.e. revving the car at standstill, dipping clutch, taking out of gear etc to see if I can diagnose it any further? What would you recommend?
I am not really mechanically minded so am wondering what it is? Could it be the gearbox? Wheel bearings? Driveshaft?
Any help appreciated .. and yes I know this may be a 'could be anything' question

try the tests youve stated yourself,, dip clutch etc..
then repost it may help...
it would help to know if the noise was there under load / not under load etc..
also check your tyres!!! it has been known

Have a WY03 WRX with a whinning noise problem. Noticable at 62-64mph - noise sounds similar to when you rub your finger around the rim of a wine glass, only a deeper ocatve.
After having it in with 2 garages they finanlly beleived there was an issue after I took them for a test drive. Appears I need a new transaxle which will be fitted next Mon.
Does this sound like your problem? Get a garage to get it on a ramp and spin the wheels and see if the noise is still there.

I've since had to switch main dealers (due to the service) and luckily a new one has opened in Dorset. Their junior engineer has heard the problems and I am booking it in for them to have a closer look shortly as an experienced (ex Chaplegate) technician has just recently joined them - I've been waiting for him to be signed-up.
I'll be letting them know about your problem, just in case.

Mine was in the dealers twice before I managed to get them to go on a test drive with me. Initially they thought it was wind noise but I kept going on able transaxle issues due to a post I read on Scoobynet months ago (well done Scoobynet) and eventually they got in on a ramp to see if wind noise was the issue.
When they got the wheels spinning the noise was far, far worse and over a much greater spread of speed. Work being done by Cheam Motors next week - I'll let you know how II get on.
Oh by the way, the noise happened regardless of gear, decelerating or accelerating, although most obvious on a constant throttle.
I also have a decelerating noise at much lower speeds. Although it’s not quite same as you describe, it sounds like something to do with the transmission. Hopefully it's related to the same fault and will be fixed next week.
Only thing that did worry me was their response when I asked about the engine overheating whilst it's on a ramp as they don’t have a rolling road facility with a large fan. Their response was, "not to worry sir, the car's fan will stop it from over heating." Hope he's right.

see here.. also an MY00 (mine). Turned out to be gearbox.
If your engine number is anywhere near mine it may of been a bearing batch problem.

Had my MY00 in to same infamous "hampshire" dealers this time last year,41,000 miles, sounded like a wheel bearing, except that it was only apparent under load in 4th & 5th. Noise and road speed were similar to your description. It was fixed on the 2nd attempt, seem to remember that they replaced the mainshaft and associated bearings. Seems that 3rd gear is weak on the 5 speed, which made mine a bit strange! "Dealer" reckoned it had never needed to strip one before. Managed to refrain from including the phrase "bollocks" in my reply.

More info from my drive home last night.
Ignore what I previously stated the noise occurs both under load and cruising.
It is most noticeable in 3rd gear approaching junctions, no power, no braking about 25 mph. Above 40 the noise is very high pitched and not really noticeable.
The noise still occurs when the clutch is engaged.
You can hear it in 3rd and 4th gear, as in 3rd to 30 whine, up to 4th and accelerate and the whine pitch increases.
Trying to describe the sound, it's not a drone, more like a fan heater whirring away in the background.
I do get occasional clutch judder in 1st as everybody else does but it's not too bad.
Is that any help .. I'll likely drop it off at the garage sometime soon but would like to know what the likely cause may be before they say .. oh you need to buy a new car

According to another thread (can't seem to find it) the fact that the noise does not dissapear when I engage the clutch rules out the gearbox .... ?
I'm starting to think it's maybe a bearing problem .. any more help is greatly appreciated.
Cheers,
Doofus.

Also did the noise worsen? At the moment I'm not sure anybody else less familiar with the car will hear it clearly .. ?

Gearbox Remove / Refit - 5 Hours @ 27.50 per Hour
Gearbox Strip/Inspect/Repair/Materials - £196 (included 4 hours Labour at whatever rate the Gearbox Specialist charged, about £40 per hour)
Total approx £391
P.S I had to wait about 2-3 weeks to get it done and in that time the noise certainly became more apparent. It's a shame we are at opposite ends of the country, cause I could of had a listen.
I took the oppurtunity to have an ADL Blueprint Clutch fitted as well at a cost of £245

I get the same noise but it's not all the time (52 Plate) - only on motorways though and like I said it's not all the time, I thought it was a wind noise at first. Is this a known issue?
#18
Never fear - can help you all out. Have just had same noise (speed dependant whine on cruising, not related to clutch position, only heard at certain speeds) diagnosed on my car. Not yet fixed! Apparently, as told by garage (proper one, NOT a dealer!) is almost certainly an early wheel bearing failure. (rear wheel in my case)
