07 GT droning from rear end

[ronnyk]

Hey all,

Have been getting a low droning from the rear end for months now. Only starts at about 50mph.

07 GT 102k

I had assumed it was the axle bearings so I took some time this past weekend to swap them out, but the sound continues albeit maybe not as intense. I put 75-140 in the diff hoping it would help as well.
The gears and axles looked ok when I had it apart.
Any ideas what it might be?

Thanks

Ronny

It's your own fault for keeping a politician locked inside the trunk.
On a serious note, the low pitched droning you're hearing from the rear could be from the tires, especially if they're getting close to their wear limit.
I think it's unlikely to be any bearing noise because that's typically more of a high pitched howl especially as road speed increases.

Thanks for the response. I got tires on it about a year ago so maybe that is part of the cause. I’ll keep an eye on them.

Rotate the tires front to rear (if you can)... see what happens.
