2013 PP SHO.
25k miles
At speed (more so over 65) it sounds like a low him (I describe it as a wheel bearing hum ) from the driver rear wheel.
Anyone experience something similar?
If it gets louder with steering wheel input its definitely the wheel bearing.
If it gets louder when turning right its the drivers side
Rear wheel.. Driver side rear wheel makes the noise. Gets louder as speed increases. Seems to become noticeable around 60+ mph
Rear wheels are harder to troubleshoot. Does the sound "pulse" or is it constant at speed.
I had an issue last year with a pulsing vibration around 55mph then would almost completely go away around 80.
Ended up being the rear drive unit or RDU.
It took ford 2 months to figure this out.
I have the same issue. Pulsating vibration above 60 mph. Definitely driver's side. My wife wrecked a wheel and tie rod ends on that side last year, and I'm pretty sure that's my issue, so I just ordered a hub.
Ended up being a cupped tire. Driver side rear, inside cupping on the GY F1's. I suppose because the car is lowered and the negative camber is making it not wear evenly.
Camber both positive and negative will wear tires on the sides inside or outside but evenly....not cupped. Toe wear will cause side to side feathering from scuffing. Sharp edges in one direction when you slide your fingers over the tire from side to side. Cupping is usually associated with balance and some say infrequent rotation.
Strange indeed. It's cupped on the driver rear inside tread...when you run your hand over it. Basically I need a new tire. At speed the noise drives me crazy.

Yes it can really howl! I agree with you a new tire is in order. I would check who balanced that tire for you and make sure they don't balance the new one. I don't know why but I have heard that regular rotation is somehow insurance against that kind of cupping. Since I don't understand why I just regularly do it at each oil change.

I rotate every six months and got 55k out of the stockers
