Further to my post from 5th sept, my wheel bearings arrived from 4WD.COM a while ago. Came to £250 including p&p, import duty & vat as apposed to the £360 - £400 i'd been quoted over here!
Fitted them myself with the aid of a very helpful "how-to" article on N.A.G.C.A. and saved myself about £250 all in.
Thanks again for the advice. Chuffed
