I am getting a bearing like whine when accelerating (almost sounds like a quiet supercharger) in my 8v M2. It is noticeable between 2k-3k revs and is present when I come off the accelerator (and freewheel for example going downhill). I tried slipping into neutral and the noise seemed to reduce, although this isn't conclusive, I may be imagining this. I wondered if I had over tightened the alternator belt but the noise isn't present when the car is stationery (I also removed the belt and there does not seem to be any unusual play in alternator/water pump pulleys). Any suggestions? Possibly front wheel bearings?
Thanks in advance

Turn the radio up! Sorry cant be any more helpful. Martin

alternator bearing i should say. dont hold me to that as its an educated guess (well with pugs anyway)
-
Ha, yeah that would work. Haynes manual didn't suggest that!

That was my initial thought but I would have expected the noise to be there when sitting in neutral and revving engine?
-
Whells bearing would be my next assumption if when moving, is it from front or rear of the car do you know?
-
It sounds like it is from the front, rear bearings were done recently so not them.
-
Have you checked for play in ur bearings? Also does it get slightly worse if you turn a certain way?
-
Deffo bearing just work out if its front or back . Had the same issue on my mk2 16v about 2 months ago!
-
Diff bearings :lipsrsealed:?
-

It doesn't seem to get any better/worse when turning left/right, it's only present between 2k-3k revs. The rear bearings have just been done, I will have a look at front ones thanks

How did you work it out?
-
Diff bearings :lipsrsealed:?
+1
Or other gearbox related bearing. Suggest you check your gearbox oil level, could be too late now.

Is there a way I can check this?
thanks

I'll check the oil thanks (if I can)
I jacked the car up and there seems to be no abnormal play in the front wheel bearings
-
its gearbox then, top oil up but i would say it may be too late now

My Jetta has the same sorta sound, checked the oil level in the gear box and was almost dry, new box going in next week

Too late now as in change gearbox? I guess if so it might be worth getting the oil changed and see how it runs for a while?
Thanks for the advice

try oil 1st, depends on how dry it was, might quiten it down. may be 2nd hand box time though buddy
-
Out of interest, does it have the same whine in all of the gears, just one, a couple and is it purely engine speed related, doing it at the same revs in whatever gear it does it in? Also, can you repeat the whine with the clutch in or it not in gear?
-
Speedo cable fecked?

they whine, i just thought they stopped workin when fecked. (lear summats new)

In terms of noise, not a big deal, not that noticeable. Hypothetically, if the bearings are worn due to low oil, the oil was topped up and then run for a while, what would happen? Would it just get worse until the box failed? If so then that would be the point to change box?
Thanks

I notice it most in 2nd and 3rd, maybe because at 2k revs the engine/road noise is enough to drown it out. It seems to be engine speed related, although again its hard to tell as it may be present between 10-40mph but I just happen to be in 2nd/3rd mostly at these speeds. I never notice it at motorway speed, only around town. There is no whine when stationary/ revving in neutral, and i think the whine reduces/disappears when the clutch is in, although this is hard to be sure of....

Could be? Speedo working fine, any way to check?
Thanks

If they are loose they catch gearbox end or dash end still work eventually it will go.
I didnt push one on properly speedo still worked but made a noise! :wink:
Easy to pull out and inspect for play and fraying.
I've experianced something simular and all it was the brake shield I had tighten too much and it was scraping the disc at sompoint It took me to jack the car up take the wheel off and watch what was happening. Don't recomend it as its dangerous as hell! :evil:
-
10mm on gearbox holds that in. if oils topped up it could last ages and then no need to change box till it goes, have you tried going down the road and putting it in neatral to see if noice stays or go? or lift front up on axel stands (or ramp and run it in 1st and listen to the diff (or where noise is coming from)

Yeah I tried putting in neutral but it was hard to say, the road noise makes it difficult to tell. I think it reduced but this may be due to the drop in revs...
-
tyr putting her on some ramps then to listen to the diff, then theres no road noice, and u can get undernieth and pin point the noice, see if theres a oil leak coming from the gearbox anywhere, normally the diff will be leaking from somewhere.

Seems like a good plan, it's going into garage in a week so I'll report back
Thanks all

Just top up the gearbox oil first, its cheap & dead easy, it should take 2 litres, I got 1.5+ litres into my last one so must have been only half a litre in there. The whine went pretty much but after another 3000mls the box went BANG!
The gearbox oil filler allen bung is on the end of the gearbox behind the front passenger side wheel. You squirt the new oil in there until it overflows out of the hole then you know that its at the correct level.
If that doesn't sort it, there's not much cash or time wasted and you can start looking elsewhere.
All three of my Golfs came with very low gearbox oil, its one of the first things to check when you buy one.

Judging by that it may not be the diff but it definately sounds like a bearing is on the way out in the gearbox and the fact most people give their gearboxes greif in these gears points me to think it may be related the the shaft these gears are on. As said before, oil may sort it for a while but it will be likely to go soon. As also said, if it can go on some ramps it will be relatively easy for a mechanic to trace the noise to either gearbox or diff if he gets a listening stick on each.

Thanks for the advice, it's booked in next weekend to get it looked at

gearboxes if the oil level is low 5th gear eats itself if its jumping out of 5th it's to late the box is dead on its feet if not may survive
what actualy happens is 5th gear ends up running dry if oil level is low so it overheats and looses it temper and hardness, so it wears away bloody quickly, this fills the gearbox with shrapnel / swarf that promtly trashes every thing that moves bearings and cogs it then rapily eats itself.

5th gear is good!

My old 020 totally lost 5th gear in the end, so I had a 4spd abf for a few weeks! Sometimes forgot aboout it and stuck it in 5th at like 100mph, was like putting it in neutral-nothing there!! Oops back to fourth!! Gold swarf oil poured from it when I removed it and smashed a hole in it for a look-see
-
It appears the gearbox oil level is normal and the oil is fine.

I am getting a bearing like whine when accelerating (almost sounds like a quiet supercharger) in my 8v M2. It is noticeable between 2k-3k revs and is present when I come off the accelerator (and freewheel for example going downhill). I tried slipping into neutral and the noise seemed to reduce, although this isn't conclusive, I may be imagining this.

Any suggestions? Possibly front wheel bearings?
Thanks in advance

Before you go in at the deep end...
You just tightened the belt and the noise started? Hmm. I reckon you should whip the belt off and take it round the block. A few hundred yards should be enough on a cold engine to let you know if the noise has gone.

I tightened it a while ago but this may be worth a shot thanks

Cambelt cover not on properly with the belt running against it. More noticeable at higher revs.
Ended up filing a bit out of mine to stop it.
Should be able to tell by looking at cambelt cover at the bottom, be melted plastic there or very slight groove.
Completely different answer to whats been posted but your gonna be fookin annoyed if you get a box changed and it was a 10 min job really.
-
Ha yeah worth checking, although I would need to know the box was buggered before replacing it and it seems ok
