Answers :

There is a TSB for replacing the IWE ( Integrated Wheel Ends ) solenoid, as the 1st design can ingest water and introduce it to the IWEs, causing low vacuum, and the gears for the IWE are grinding.

To cure this until you get the new IWE solenoid ordered and installed, pull the vacuum lines from the IWEs and plug them. This will leave the IWE gears engaged, so they are not trying round off the teeth.

There are 2 lines to the IWE, 1 is the vacuum line, the other is a vent line, that routes into the engine compartment, with an open end, make sure you pull and plug the correct line.

This will have the front hubs engaged to a dead axle, so it will decrease mpg, and you will feel a bit of loss of power, but better than ruining a set of IWEs that will cost ~500.00 to replace.
