Thanks

Perhaps check the wheels first? Buckled or flat spots can give a vibration.

Propshaft imbalance, centre bearing shot or the rubber doughnut breaking up ?
Loose wheel nuts ? ( yep, it do happen )
Rear wheel bearing breaking up ?
Or it could be the dreaded Cattle Grid Syndrome.
top gear at 35 mph ? are you sure ? 
O/D should only kick in at at around 50mph.

Get a slight rumbling in mine at 38-42mph in 3rd and 50-54 mph in o/d, only if I press the throttle and knocking it down a gear takes it away completely, been there since I've owned it and never got any worse, I just live with it, normally keep it out of o/d until 60 anyway 
Checked most other things (indeed had most other parts of the car replaced  )), I know it's a propshaft bearing or something, assumed it'd be replaced along with the gearbox but no such luck

Before trying anything else, clean the MAF. It cured my 16v.

I've always had a small vibration ( Ooooer ! ) at about 40-55 mph , I'm figuring it's the propshaft centre bearing or the propshaft/diff bolts been re-fitted wrongly in the past .
As it ain't got any worse in 2 years and 22 000 miles, I'll just leave well alone.
