My Disco makes a whining noise when I'm driving (and I've not got a puppy stuck under the bonnet). It's a bearing, somewhere in the transmission. The whine seems to speed up with the wheel speed, not the engine speed, and the noise fades when coasting or going downhill. People have suggested either gearbox or transfer box, which sounds right, but is there any way of isolating it further so I know which is the likely culprit? I don't want to remove one to find it's the other!
Secondly, once I know which bearing it is, how difficult are they to replace? I'm OK with spanners, and have changed gearboxes in the past, but never dismantled one.....
