Check the u-joints, wheel bearings, driveshaft balance or backlash of the gears.


The gear change has to be absolutely to spec, otherwise - humming noise. Is it a higher-pitched hum or lower-pitched hum? Is it constant or does it change when cornering? Does it change under load? Does it disappear when depressing the clutch at speed?

Make sure diff is filled to proper level with lube.


It's a low pitch hum, and goes away with throttle off, but continueious while using throttle, I to had my gears changed and that's when it first started


Sounds like the mechanic didn't set the backlash correct.
