powertrain warranty?
 

I have a 2007 Ford F250 superduty 4x4 5.4.I think I might have a frontwheel bearing going bad does anyone know if this is covered under the powertrain warranty.

I'm pretty sure it's not. I asked a lot of questions when I bought my '07 F150 and powertrain is described as power to the wheels, and only items internally lubricated. I know a wheel bearing comes pretty close to that definition but I think Ford is covering engine and transmission items. They would consider a bearing to be a normally worn out part.
