Oh dear. Mighty Volvo gone cucumber! (sorry, that's a Scandinavian joke).
As a vehicle test engineer (retired) my first guess was inter-axle differential (if it was mechanical noise), but I'm not so sure.
Unintentional increase in speed / speedo going wild / vibration. Maybe it's engine-management / fuel?
Could've helped you more if it was a DDAD (Detroit Diesel).
