Like the title says, my trucks makes a humming noise while on the gas. It stops when i let off. What could it be?

 

we will need more info. tranny noise? engine?......

 

I don't know what you mean by a humming noise, but if its a whine it could be the pinion bearings going bad. But like thunder98110 said, we need more info!

 

Also could be your cv shaft

 

my truck hums when i play blue grass music

 

I'm not sure where the noise is coming from. But it's only when on the gas. I just put in a rear end with only 56k on it. Its a 9.25 12 bolt with limited slip. The truck made the noise before i changed the rear end.

The truck is an 01 3.9 Auto

 

Typical Dodge. It's happiest when you're on the gas!

 

couldnt agree more !


also check u joints make sure they are well greased a buddy had that problem ended up being u joints .

 

i have the same prob with my 01 dakota 4.7 only makes the whine/hum when giving gas also happens when slowing down. when im coasting it doese nothing pich changes with speed thou please help

 

Wheelbearing, cv axle, ball joints, i heard the same noise and checked them all and they all were bad. if you turn left or right and it sounds like your rubbing it's definitly your wheelbearing
