V70 Manual Gearbox Whine

Comcastle · Jun 28th, 2015, 17:12

Having had the 2002 V70 2.4 for a few weeks now, I've noticed that there is a whine coming from what I assume is the gearbox when driving. I've done some research on the interweb and there appears to be very little out there for the manual 'boxes.

The noise can't be heard on idle, and is only audible when in gears 2/3/4, and is a metallic whine that is there when accelerating and on overrun, but if you balance the throttle where its not quite doing one or the other the noise reduces.

Speaking to a Volvo breaker he said that its not all that common for the manual 'boxes to have issues (the car has 120k on the clock) and suggested that someone might have put the wrong oil in at some point, or that it had no oil in at all.

Today I drained the oil in the 'box (it was dirty and runny) and put the correct oil in, but after a short drive there's no difference sadly, so I'm a bit stumped as to what could be up.

Can anyone offer any advice on what the problem could be? I have found some information that talks of a "throwaway"? bearing in the gearbox that causes this noise, so a replacement clutch, pressure plate and bearing is needed, so could this be what's up?

Thanks for any info on the matter.

Check for oil leaks.
Replace oil and try again.

You could be right. How bad is the whine? Is there any sign that the clutch is on its way out? A new clutch pressure plate and (ouch) labour can be expensive if the whine is minimal.

The car is perfectly drivable, although the gear change can feel a little knotchy at times. No sign of a slipping clutch, it pulls as I'd expect it to, its just the noise. Stereo on and it can be drowned out as its not hugely intrusive, so may be something I just have to live with until the clutch needs doing perhaps.

You could try some gearbox additive, it might help.
