What should I do if my F150 makes a grinding noise?

Connect the vacuum pump to the vacuum line running from the IWE solenoid to the IWE hubs. Pump up the vacuum and see if the vacuum holds while rotating the front wheels. The vacuum should not drop more than 1-in/minute. If vacuum drops faster than that, check for a vacuum line leak or a leaking IWE hub.

What makes the grinding noise in a Ford F150?

Ford IWE Hub and CV. The IWE system consists of a vacuum reservoir, IWE vacuum solenoid, IWE hubs, vacuum hoses and a check valve.

How can I tell if my F150 battery is working?

If you see full battery voltage with the key ON, check for good ground from the PCM on the red wire when the vehicle is in 2WD mode. If you see battery voltage and ground, check for manifold vacuum on the vacuum line that runs to the IWE hubs. That will confirm the solenoid is operating properly.

Why does my car make a grinding noise when I Turn on the vacuum?

A vacuum leak in the vacuum hoses, reservoir or IWE solenoid can cause partial vacuum application to the IWE hubs, causing them to PARTIALLY engage. Since there’s some vacuum at the IWE, the hubs are neither fully on or off, causing the grinding noise.
