Well it's been sorted, old bearing completely toast, rough... however an old noise that I thought was the wheel bearing progressing is still there... perhaps driveshaft?
Happens around 20-25mph, on load more than off... then completely disappears ... it's been there for about 2 years... no splits in the gaiters, but I have had them replaced a while back so perhaps some ingress.
Anyway, cheers for the input guys. (y)
