4x4 trouble (already replaced module!)

[bjesse60]

Hi, i am having the same issue as i see many others have had here my 2002 is still wanting to engage the 4x4 randomly, the module has been replaced already and all buttons and lights are working correctly with no codes. My next guess would be maybe wheel speed sensor bad am i in the right direction and how can i narrow it down to which one, can i test them individually? Any info is appreciated!
Thank's Brandon
