I have a 2011 outlander max LTD. I’m having a couple issues with the front diff – i think. The first thing is it won’t stay in low gear for very long while riding around on all terrain. The other is, on steep hills when i start out in low gear the front diff starts to make a clicking sound and then it pops out of low and free wheels down the hill. Any ideas what could cause this? and how do i fix it?
