Almost OT, VX Astra gearbox noise
As some of you on here will have the same gearbox I thought I'd ask your opinions. My wifes car is a 2008 1.9cdti VX Astra with the 6 speed 'box (M32 I think) with 81k miles on clock. The car has always been a bit stiff to get in and out of gear, this has not gotten any worse but I noticed when driving it yesterday that there is a whine coming from the front. I'm sure it's not wheel bearing related as I've just had that issue on my own car.
The whine is very similar to diff whine and raises and lowers with speed. I'm not sure at this stage if the whine is affected by which gear is used nor am I sure if it changes when changing gear. I do know the noise has been in the background for a while but yesterday it seemed a little more audible.
What are the symptoms of these 'boxes failing?
