Wheel bearing?

[85eurocarrera]

If it is right after startup it is most likely IWE disengaging. The cornering thing could be an IWE locked in as well. Spend some time to diagnose them, check your CV boots out. Check the wheel bearings with one tire up before you start pulling things apart. The wheel bearings on these are pretty expensive, and not a common fail point so make sure!

I will take a look underneath today.

The mechanic I use is old school, diagnose and replace as needed. I trust him and will pass on all your guys comments.

so ‘if’ needed wheel bearing/hub is Motorcraft the brand to get?

Don’t forget the procedure that @FordTechOne mentioned when doing the replacement, something about having the iwe on a vacuum while placing it in the hub. Make sure your mechanic knows about that. And loctite on the axle bolt.

Motorcraft (SKF) or Timken unit bearing is the way to go.

Update.

The CEL was Purge valve.
Needed inner tie rods, driver side was worse. Front tires were wearing a little ‘choppy’. Rotated fronts to rear. No more noise or buzz in steering wheel. Noticeably tighter up front now.
