I just got done changing the front brakes on my 2005 F-150. I noticed the vacuum lines to the IWE were severed on the passenger side. What should I be concerned with? I have no noise or “rattle.”

Since the hub is engaged with no vacuum it looks as if I’ve been driving with a locked hub. Would that cause damage to the hub? I intend on replacing the vacuum lines once I get a free moment.

Can I test the actuator by putting vacuum on it from an electric vacuum pump?

Any help would be appreciated.
