I'm a noob to this board, so any info is helpful. I have a 94 Stang V6 and over the last few days it started getting a low pitch humm at speeds of 55-65 when I let off the gas. No real vibrations, but it doesn't sound right. If i get back on the gas a bit it seems to go away, but not completely. any ideas??

It sounds to me like what you hear is the engine winding down. My 1994 Ranger does it- nothing to worry about. However, if the noise gets louder, do post up and let us know.

it has gotten a little worse. I have talked to a few people out here that say it may be the rear diff. I had the tranny rebuilt about 2 years ago and need to take it in next week for a check up, but am hoping that that will fix the problem. I have had the car about 3 years and this is the first time it's done this.

Thanks for the help

It could be your gears, but that's rare when the differential isn't opened up for modifications or repairs.
Let us know what you find.

Sound like your gears are worn and may need to be replaced. The sound is normal when gears have been replaced until broke-in. For the age of your Stang, recommend you get the gears and fluid level inspected and replace gears as necessary.

can you chage the pitch of the noise when getting on and off the throttle is so the pinion and ring gear is shot expect to pay big bucks for this repair this would be a good time to change your rear end gearing too
