My Matilda has had three new sets of wheel bearings in the past 2000 miles...

Now the funny ve-vum-ve-vum-ve-vum-ve-vum noise is back & is getting louder & I can no longer ignore it or drown it out with music.

I find it hard to believe that it could be a third set of faulty bearings, so what else could it be?
Any ideas from you Egghead-types, please?
