It seems I have a low hum from the driver rear tire area on my 2013 PP. Is there a TSB out for this, anyone else have a similar issue or am I just crazy.
If definitely from the tire area, possible wheel bearing. Does it vary with speed? Have seen WB problems being common on late model Fords.

This TSB might be the issue as it seems to be in the wheel bearings.
I had the TSB done; my wheels still creek.
I just got over it and kept moving.
Only time I really hear it is if I'm in a parking garage and I turn wheels either way or shift from reverse to drive/or vice versus.
I am having the same issue with my 2010. Already had the driver side axel shaft replaced. That did help. But now I hear the same noise again, possible from the other side, and quieter. I'm gonna take it in to Ford. I'll update when I know more.

I have a 2013 SHO PP and mine has a rear end vib decelerating from 55-50 and then when under 3/4 power accelerating from 50-70. Most of my past experience was with rear drive vehicles and I think the vib is originating from the rear differential unit. I noticed the vib from the day I purchased the car new and it now has 36,300 miles. Brought it in and they told me its bad tires, so I just put a new set of tires on it just to appease the dealer tech. I read on another forum this guy had the same issue on his 2013 SHO and his dealer changed all of the rear bearings and half shafts before changing the rear differential unit. In the end it was the RDU that fixed the vib for him. I'm bringing mine in Wednesday for the FPDM recall and I'm going to have the tech drive it again. I'll keep everyone posted. I'll also post the link to the other forum where this same issue was fixed.
Crashnburn, I had the same problem with my 2010 sho.
They said it was a bent rim, changed the rim, vibration still there. Replaced all 4 tires, vibration still there. Then they finally started replacing parts under warranty. They replaced the driveshaft, all 4 wheel bearings, PTU, awd control module, and finally the rear drive unit fixed the problem.
Glock-coma, I think it may have been your post I saw on ecoboostownersforum about this topic. Most people don't notice the vib so it's hard to get the dealer to fix it. Did they find anything wrong with your rear diff after the removed it? Or did they just change the part?

They just replaced the RDU. They said they're built to order, so it took about a week to get the RDU in. The part was returned to the manufacture, I assume to break it down to find the bad part. Service manager said they don't replace components on the RDU, just replace the whole unit. If you need my dealer info for your service dept, send me an IM.
Thank you for the help. It is much appreciated.
