I had to have read every thread on here, on the IWE vacuum solenoid, valves, hoses, hubs, etc, issues, and only once or twice have I come across mention of the setup- as it is on mine (2009 F150 v8 5.4L). I have the one with the solenoid up on the radiator shroud, as opposed to near the firewall, or by brake booster, or wherever else it’s migrated to over the years... whet’s up with that?

Anyway, what I CAN’T seem to find, is what part number it is that I need, to replace the hoses. I’ve changed the solenoid and check valve (or are there more than one of those?), but I still get this faint, “loose washers on a bolt” jangling, when I’m turning right, on a 35mph sweeping curve, but only if I’m doing about 40mph, and it’s usually only in the afternoon, on way home from work.

I don’t think the hubs are toast, unless it’s they that aren’t holding a vacuum(?), so I want to try changing the hoses next- they seem brittle and dry, anyway.

So, long story short, anyone know what that part number is, for “iwe vacuum hoses” (replacement kit?), for a 2009 f150 5.4l V8, for the one with the solenoid mounted up in the radiator shroud, near/on the vacuum resevoir?

Thanks,

Thank you for the link on the iwe line potential weak point(s). I’ll give that a look tomorrow... that would be so nice if could isolate a tear, and repair it with some new hose spliced in.
