Very slight Frank, when on ramps it's a case of 'catching' the right revs to make the whine happen. When driving it's pretty constant at the speeds above.

I think it's fair to say, more pronounced under some load.

Today, i loosened the center bearing, ran the drive train up 40mph switched off, locked up bolts, same.

Drive train to my eye is pin straight no wobbling or distortion (new center bearing too).
