Any 4WD experts here ??
I posted in another section but its probably not the correct one... I have a '98 3.0L Ranger with a 4WD issue. It never really functioned well in 4WD-high, but the 4WD-low always worked well. One day however, I accidentally hit the switch to 4WD-high and the unit locked in and I was not able to get it out of 4WD. A friend helped me get the 4WD motor unit off, and using a wrench and lot of muscle, we did get it back to 2WD, where it remains today. The drive unit which we removed was badly rusted and corroded, so I thought this must be the problem and bought a new motor drive unit.
When I plugged in the new unit, I tested to see the motor function, and thought I could then just slip in on, bolt it up, and away we go ! Not the case ! The motor never moved a bit when dialing the "selector switch" and the motor output position is such that it cannot be fit onto the 4WD input shaft. I also replaced the dashboard selector switch just in case that may have been bad.
My question to all the experts here is: What do I have to do to get the 4WD motor unit into the right position, and if it doesnt move how do I energize it ?? Also, could it be the 4WD controller module that has gone bad ( wherever that may be ) Are there Relays involved that I cant seem to find ?? I'm now desperate and just need to know where to begin and what to do !!
Any help or advice would be greatly appreciated !!
Thanks in in advance for your help.......// Ernie in NH
