2003 euro wheel bearings

[Digs]

Hi guys this is my first post ! so i hope im in the right forum. When i drive over about 30 kph i get major noise coming from the rear wheels . i have replaced all tires after the problem started, no change! I took it to my local honda dealership and they told me that the rear wheel bearings were U.S after only 80,000, So i jacked the rear end to isolate what side was shot but they both feel and sound fine ( no rumbling or wobbling ) I know the rear bearings are a sealed unit on this model so is it the way im trying to test each side or what?? I only wish to replace the shot side because each bearing costs around $300.
Any clues?
ok wrong section sorry please remove:[

I just did the front ones on my ek , problem i had was they only made noise when under load so that when you jacked the car up they went quiet ...
And yes $200-300 per bearing fitted is the norm ...
