My 4 high will work with the hubs on auto lock but only periodically. Works great for one drive in 4 high, shut truck off for a bit, start it back up and shift it back into 4 high and get the Check 4x4 light with wrench on the display. If I lock the hubs the 4x4 seems to work just fine. I had to replace the passenger front hub recently and everything worked fine before that. The install of new OEM hub went well with no issues other than the auto locking 4x4. Any suggestions as to what I need to look for to fix this problem without taking it up the the dreaded Ford Dealer?? Thanks in advance
