where is that located? just so i know general areaLot of miles on truck, have you checked the vacuum lines to the 4 x 4 control module.
Bad solenoid would cause vacuum leak causing the front wheel IWEs to remain engaged in 2WD. Checking would require vacuum gauges, etc. to do any real testing and probably more time than the actual part replacement. Again, use the OEM Motorcraft/Ford product for replacement, not an aftermarket.how can I test the solenoid? would that cause hard shifts even when only in 2wd? I have no codes
