strange rumble

Hi everyone,

Today I changed the gearbox oil and front discs and pads.

Put everything back together took up the road to bed in brakes and I heard a strange rumble when you get to the higher rev range.

Everything was tight nothing lose and it didn't do it before.

Any help would be great

Thanks

Lewis

Video would help
 
I haven't got one at the minute but I did notice that the under tray was missing a bolt could it be possible that it could be that vibrating?
