Deep humming noise

[MacD]

There is a deep humming noise when driving over thirty... don't think it's the engine ...could it be from wheel bearings ?
The steering is unaffected .

Is it louder on bends, left or right?

Jack the front up and loosen the brake adjusters and spin the wheels, any rumbling or roughness , could be wheel bearings.
Then jack the back axle up on axle stands, start the engine, put it in fourth and rev it up till the speedo says 30, any noises?

Try a short run without the fan belt fitted........

[MacD]

No difference left or right!

Any oil in the final drive ?
