Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
Does the front axle actuator engage?
I can only hear the transfer case engage.
i do not hear anything in the front end
Ok, take out the front axle actuator and see if it extends.
I am unable to working on the truck today. if the front actuator fail would this keep the light binking?
Yes, because the system is waiting for the front axle to engage, they are common for failing on these.
It had been working early in the day. i son got the truck stuck in mud and had to be pulled out. After that the four wheel drive would not engage again. The front end was pulling when i was pulling him out of the mud.
Ok, so it is physically engaging but the light is flashing.
does this have the 2 wire actuator or the 4-5 wire actuator?
Will it mess up anything by driveing the truck in this shape? I will need to get it the a shop for repairs.
No, it should not, but if you do hear or feel it grabbing, then you can drop the front drive shaft off to get it ther.
