2001 f250 super duty transfer case noise

SOURCE: a grinding noise in the front end of my 2002 f250

If it is a 2 wheel drive, it is probably your wheel bearings. If it a four wheel drive, it could be the front differential, the joints on the axle shafts, the locking hubs, or the wheel bearings. On the four wheel drive, crawl under the vehicle and grab the axle shafts and see where the excess movement is. Also try grabbing the tires and see if there is any movement. There shouldn't be any movement while the wheels are on the ground.

Low boost. Here's a detailed forum explaining several techniques for trouble shooting.

I have a similar issue on my 2001 F250. Apparently there is a technical bulletin that describes cleaning the hubs to prevent small plastic engagement lugs within the hubs from partially engaging the hubs without being "instructed" to engage. This causes bearing-like vibration & noise. We cleaned my hubs at a local truck & car service shop (owned by neighbor) and the problem went away for 1 week. Its back now same as before. I don't have a solution and am thinking about trashing the factory hubs and going with maunal Warn hubs or equivalent. Anybody else have any solutions?

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!"

You need to specify that if the diagram engine or that. Thanks
