Wheel bearing wows

Hi All. Hope you can help please. I've just had a noisy diff sorted on my 07 Freelander 2. Its almost bliss now apart from a new noise from the back end. I guess this noise was masked by the noisy diff. To me it sounds like a wheel bearing. I'll try to type what it sounds like. Here goes...woowoowoowoowoowoowoowoowoo. now its driving me mad. Any ideas chaps?
Thanks in advance guys.
Regards Dave
