"4WD" and "4WD-LOW" lights flashes approximately 5 to 6 times. on 1997 Ford Explorer

I have a 1997 Ford Explorer XLT Autotract 6 cylinder with 222,000 miles. It has automatic transmission, power steering, and ABS. Two days ago I started experiencing a binding sensation from the front end when making a sharp left or right turn. Since then I have noticed that the "4WD" and "4WD LOW" indicating lights flash six times than go out. This repeats at exactly two-minute intervals. While driving the vehicle, I switch to full time 4WD but nothing happens. If I stop, shut it off, starting and put the truck 4WD, and then switch back to Auto it appears to temporarily solve the problem; however, this problem has occurred several times over the past two days, but only at low speed. e.g turning in/out of a parking space. Any idea what may be causing this?

I would suspect that there is some binding and wind up of your axles due to an issue within your transfer case. The light flashes likely because of the same issue - as the system attempts to shift, there is some kind of failure occuring. With the age and mileage of the truck, it's not terribly surprising. You will need to have a qualified technician examine your 4x4 system.

4 years ago I had the exact same issue on my 97 Explorer XLT and it was the transfer case. I had it replaced and it resolved the problem until maybe 2 weeks ago when the lights started flashing again. There isn't any binding or noises but it also will not go into either 4wd High or Low. Just a sensor or do I need the transfer case replaced again?

It's possible that you have recurring transfer case issues. Make sure your tires are identical in size and condition, tread depth, etc. Was the transfer case you installed a remanufactured or new unit? Or was it used?

Check out the serious explorations website for ford explorers. It will show you how to replace the electrical connections going to your transfer case that have become bad.
