well I dont use my 4x4 on my 2003 sp 600 much but I did use it in the snow the other day; and it worked wile in 4x4 but when I took it out of 4x4 it would not disengage consistantly.....it would engage wile the switch is off...even after backing up for awhile with it off....doesnt have problem in reverse though....changed the oil this falll so that should be good...whats the deal?????? thanks

 

Mine does it too. See my other post from 2 weeks ago for more info.
