Drive Train Axles Bearings problem
2000 Ford Ranger 6 cyl Four Wheel Drive Automatic 65000 miles
My 4 wheel drive HI does not disengage normally and makes a loud " howl" when engaged.
Two wheel drive is fine.
4 wheel LO drive is disengages normally.
In 4 wheel HI (and LO) there is a loud " howling" sound like when you drive on pavement with mudder tires.
In 4 wheel HI I can turn off the switch and the light goes off. However it actually stays in 4 wheel HI, sometimes for miles sometimes for ever. When (if) it does finally come out there is a significant bump like when you drive through a pothole and the howling stops.
I can also get it to come out of 4 wheel HI by turning off the switch and then at any time after that (right away or miles later) if I make a hard turn either right or left.
If I stop and put it into neutral and turn off 4 wheel HI (like you do with 4 wheel LO), it still stays in 4 wheel HI.
I had the truck into the local Ford Dealership for 3 weeks and they were unable to fix it.
They did the following:
1. Replaced fluid pump and forks in my Xfer Case.
2. Put in two (2) replacement Xfer cases.
3. Checked the front differential.
Everything looked great and met all tolerances.
4. Put a different type of fluid in Xfer Case.
5. Gave up and refunded my money.
