transfer case noise

[larrym1845]

I have a 2000 ranger 4x4 and when I put the switch to 4 wheel high I hear what sounds like some grinding like its not meshing in gear.When I stop I can hear it whine down and then will stop and it seems to mesh.

Your Transfer case has a clutch in it that enables the shift into 4Hi without that noise.
Yours isn't working!

You'll find that when you shift to 4Hi, 12v power should be applied to the BROWN wire going into the transfer case. If that power is not present (truck only needs to have the key in Run for this test, not engine running), you should replace the Electric Shift Relay which is located inside a plastic relay box on the underside of the DS dash, near the GEM, somwhat left of center dash area. It will be a small 6" or so plastic box, taped shut, buried up in the dash.

I found that relay box by laying on the floor looking up, head by the gas pedal, looking toward the GEM (which if you remove the radio surround bezel, you'll see the GEM on the left side in there). It also contains the Battery Saver relay which shuts off your power to the PW after 30 sec if you don't open the door and turns off the Dome light if your door is left open. If you don't have power windows, you won't have the Battery Saver relay if I recall correctly. But the Electric Shift relay should still be in there.
