Having problems with your 2006 Ford F-150 ?

The vehicle is a 2006 F-150 FX4. The problem I am having is the 4x4 disengages under load. I have replaced both hubs, actuators, both check valves, and the solenoid on the firewall. All replacement

\015 The vehicle is a 2006 F-150 FX4. It has the electronic shift on the fly. The problem I am having is the 4x4 disengages under load. It will re-engage after a bit when i let off the accelerator. The light on the dash reamins lit the whole time. I have replaced both hubs, actuators, both check valves, and the solenoid on the firewall. All replacement parts were Motorcraft. I have also checked the vacuum system for leaks with a vacuum gauge and the system operates properly. Is the transfer case the problem? Are my new actuators defective? Anyone want a 2x4 FX4?\015 Posted / edited by AnonymousUser on : 13-08-2018

Answers :

Okay looks like you covered all the main things but one thing left is the shift fork in the front diff. i have seen this problem and some were due to bad hubs and others bad solenoids or bad vacuum line and the last problem that i have seen were it comes out of 4x4 but lights stay on and that due to a bent fork, this fork is located in the front diff and is what engages the front wheels, there is an updated fork for this truck. i did not repair this as the customer wanted the dealer to the job hoping it was warranty work but ended up having to pay, the advised me that it was a bent fork causing it to jump out of 4x4, the csot was about 750.00. I hope this is helpful and solves the problem, let me know. good day.
