Hello folks,my trucks has been going into four wheel drive on its own and the indicater light on the dash will not show thats it in 4x4,i only catch on when the light flashes for 4x4 low.It has happened on a long trip going 120 on dry pavement,i don't think that itsgood at all,i've got a little fiberation and its comming right under my feet.i took the drive shaft off and the constant velosity bearing has a bind in it when i rotate it by hand,so i put a brand new shaft on,any idea's why it would go into 4x4 and not show that it was in 4x4,any idea's ,thanks

For 4X4 low to actually engage there is a set procedure and it is difficult when you are actually trying to engage it. If it's selected but not engaged I believe the light flashes. If yours is not selected and the light is flashing perhaps it's not fully disengaged or the switch is asking of it and it's not engaging. Oh for a manual xfr case.

Hello Busboy,i know i have to be stoped for it to go into 4x4 lo , but it actually flashes when i driving 120 0n the road that it wants to go into low range,it got me the first couple times when it did go into 4x4 with lights showing on the dash that it was not in 4x4 ,but now i can feel it in the wheel. When the wife drives it i don't think she knows when it doe's it,my son knows its been happening to him in it. the switch works fine too if you turn it on it goe's into 4 wheel drive when you turn it off it goe's off, but every now and then it goe;s into 4 wheel drive and doe;s not show on the dash that it is.Its going into the shop tomorrow and i know that there going to say the switch works fine.thanks for the reply
