I am having some problems with switching out of four wheel drive. S when I flip the switch back to 2 wheel drive everything seems ok at first, but within a mile or two I will hear this grinding coming from the front that sounds like the gears aren't completely disengaging. The inky thing that prevents this grinding from happening is switching back into fire wheel drive and keeping it there. Any ideas what might be causing it to not stay disengaged ? Thank you for your input in advance.

 

Mine only hung up on me one time. Putting it into 4wd again and switching to 2WD while backing up seemed to have worked as I have not had any trouble since. BTW, that was in the middle of winter here and it was -15 that day, so I don't have any doubt that the weather was a contributing factor..
