This has got progressively worse over the year, only does it over 45mph, not an engine noise, definitely a bearing type whine, now I've ruled out wheel bearing if it was a Land Rover I'd say it was front diff.

I have an 05 plate Grand Voyager 2.8 CRD Auto which I love, however, since I bought it (which was a year ago) it has had a whine from the front most noticeable on motorways which got worse when turning left. Everything pointed to wheel bearing as the noise had got pretty unbearable I finally got round to replacing the RH wheel bearing, to my surprise it made absolutely no difference. I've read about gearbox issues on the autos but it changes perfectly which leaves me completely flummoxed. Has anyone come across this before or have an idea what it could be?
