I have a 2009 expedition limited 4x4 that we drove through some Highwater recently. Started noticing a grinding noise in the front. Looking at the F150 threads it sounds like the problem might be the IWE solenoid. Problem is I can’t find it on my expedition. On the F1 50, it’s behind the battery on the firewall. Mine appears to have a plug in the wall there. Does anyone know where the solenoid is on this model?
