[QUOTE="FordTechOne, post: 1638664, member: 35543"] There is a specific procedure that needs to be followed when replacing an IWE (locking hub). The IWE must be compressed fully and capped before installation, and the depth of the threaded shaft must be verified to be at least 15.5mm from the inside of the hub. If those procedures weren’t followed, the IWE may exhibit a repeat failure and grinding noise. DTC P184A indicates that the transfer case shift motor position has not been reached after the maximum number of allowed blocked shift attempts between 2H and 4H or 4H to 2H. Diagnostics instruct to remove the t-case shift motor and observe the motor position while switching between 2H and 4H. If the motor rotates, the t-case should be manually shifted between ranges to check for binding/damage. If the motor doesn’t rotate, the circuits between the TCCM and motor need to be verified.
