2006 f-150 transfer case making grinding noise in 2wd, noise stops when switched into 4wd

SOURCE: Transfer case is making a grinding noise in 2wd,

Depending on how long the grinding has been going on, the IWE ( integrated wheel ends ) might need to be replaced.

The problem that causes the symptoms is either cracked vac lines from the IWE solenoid, or a faulty IWE solenoid.

Check the vac lines to the IWE, this is the block diagram of the setup


Use a visual inspection and vac tester ( might vac with a gauge on it ) to test the lines.

Testimonial: "great! It was cracked vacuum lines. Thanks for the feedback!"

This sounds like the front hubs are trying to engage. This motor/4wd is real susceptable with vacuum problems. I let my oil get real dirty and it caused the low vac.The dealer performs vac test for front IWES (3c247) and found both of them leaking out of tolerance. This also caused damage on the splined contact points so they had to replace both front wheel hubs (1104)
