Gearbox Whine........Update picture

[richnewton]

I have a strange whining noise when driving which sounds like its coming from the gearbox, the sound is high pitched and sounds like a straight cut box on a mini. any suggestions?
cheers rich

Rather than driving it up the road, I'd be jacking up any one of the rear wheels to carry out a static test. You will then be able to identify which end of the box the noise is coming from.

Does it go away when you take your foot off the power?

Have you checked oil level/changed oil lately?

aye a job for tonight i'm thinking.

cant remember if it does go away, will check tonight, changed the gearbox oil about 3 years/8000 miles ago but not checked it for a long while

[richnewton]

ok so i have jacked it up and stuck it on axel stands and run it through the gears.............. no noise.
when driving it home tonight the noise stops when the clutch pedal is pressed down.
all suggestions greatly appreciated.

does it do it in neutral with the clutch out but not with the clutch in ?..could be the clutch release bearing

[Aidan]

input side if it goes away with clutch depressed and vehicle moving, so that's either clutch release bearing, spigot bearing, input bearing, mainshaft bearing, 3rd, 4th and reverse idler which is actually on the input shaft on Aircooled.
If it just takes a slight dab of clutch pedal to stop it I'd suggest that it was release bearing.
And I'd do an oil change if you don't know the state of the box

do an oil change rich and see what joys are stuck to the bung when you get it out.
then turn the stereo up
i had a similar problem many years ago with a 2.0l mk4 cortina. it developed a whine and lots of strange noises ensued. i was skint at the time so just had to nurse it and see how it developed. then one day me dad said "have you checked the rubber gaitor around the gearstick" i did and it had split, allowing me to clearly hear all the normal clicks and whirrings that couldn't usually be heard inside the car. changed the rubber boot and it was silent again

[gti mad man]

oil changes are def worth doign though results can be scary as im currently experincing lol

[richnewton]

going to change the oil tonight and see what that shows, thanks for the replies

hiya folks, i have a whine on a bmw 320i, i think it's coming from the left axle, could be a bearing, but could it be the diff, does the diff oil run through the axles to the ends of them near the bearings? how could i diagnose this? cheers.

[richnewton]

drained the oil and was expecting the firtree as per wikibut there are a few larger bits on it


now do I refill with oil and see how it goes or put the spare box on (unknown condition) and see how that one is?

[badger]

think I'd drop the spare box in and see how it goes.

enter aiden, stage right to massive applause

imho that wants a rebuild, see what the unknown box plug looks like, but really only way to tell is to drive it
try http://www.bearsmotorsport.co.uk/Volksw ... ge-VW.aspx for Aircooled as I don't do them, I have heard good reports of them and they aren't far from you I guess
