Question Low Drone from rear end

hey people, for the short time i had my music low,...i noticed a low drone sound throughout the car...raising the rps has no effect and its not the exhaust,

it was most noticible this morning while the car was cold...olmost sounded like a grinding..but not quite, i have a feeling its the beggining to a big costly problem....i hope not...anyone have any idea?

More description would help, but here are a few things I'd look into first. I'd get the rear wheels up and check the hubs/bearings. One good way is to grab the tire top and bottom and try to rock it back and forth. There should be ZERO play. Also, you can rotate the wheels and see if you hear anything from the hub.

You didn't say if there's also vibration, but if so, suspect the U-joints. Also, each of the halfshafts has two joints, and these make noise when they get worn. Just to be sure, I'd check for oil leaks around the differential (especially the seals where the halfshafts go in) and I'd also check the oil level in the differential. Should be right at the hole when you remove the fill plug. Finally, make sure nothing looks strange with any of the tires. A tire that's defective inside can make a lot of droning noise. (But no grinding noise)

Sounds like the fuel pump. Does it do it when you are just sitting still at an idle. If it's getting noisy the pump may be failing. Ford pumps usually get noisy before they go, chevy pumps seem to go with no warning.

Hmm..I had a drone/slight grinding noise coming from the rear end also. Not suspension related, and was not heard at all if I was giving the car no gas. As soon as I even lightly touch the gas pedal, the noise would come back.

No holes or anything like that in the exhaust, so my guess is differential?
