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.

So I’ve replaced the front hubs and the sound has stopped. I replaced the hub nuts too, but the wheel feels like it has play in it and wobbles on curves.

Is this just poor hubs or was I supposed to reuse the stock nuts?

Ford says use new nut with 300 Nm.
