Hi all, first time here to the forums.
I have a 99 XLT 3.0L 4x4 and I am pretty certain that my 4x4 is not working. I have searched the net for various help on diagnosis but still I can't figure out the problem.
I'll start from the top here... When I switch the truck to 4x4 hi via the switch on the dash.
Everything seems to work perfectly.. the light on the dash switches to 4x4 and I can hear the actuator clicking to the next position underneath the truck. I have even removed it completely and tested to make sure its working and it definately is. However the 4x4 still does not seem to work. I have tried mashing the gas in the snow to see if I could see spin marks but the truck still moves with just two wheels so that isn't helpful. I also tried putting it in 4x4 and making sharp turns.. as of yet I haven't had it "hop" on me. Which makes me believe is not working.. Also last winter I got stuck in my driveway with only a tiny notebook size stack of snow on the ground while my truck bed was full of wood.
So this also makes me believe that the 4x4 is in fact not working..
I suppose my question is how do I go about fixing it now...? I haven't ever done 4x4 repair, though I am not exactly a stranger to mechanics. I'd like to zero in on the most probably cause of the issue and try fixing that.. I don't have alot of money and this is my only vehicle.. so if I have to take something apart (which i'm sure i will) i need to be able to wax it all out in a single day.
Thanx for any help you guys can offer me
