2002 explorer Transfer case Problem...4x4auto/high/low

[not8taxi]

whats up everyone...any input on my problem would be very helpful...This is long so my real question is all the way at the bottom ...thanks

i have a 2002 ford explorer xlt with the 4x4 auto/high/low setting on my transfer case...in may of 2010 i had my transfer case replaced with a rebuilt unit...(the original one was on its way out)...about 7 months later i was hearing a noise and brought it back to the mechanic and the truck was put on the lift...come to find out the transfer case was making a noise and the front wheels were not engaging...after a week of waiting they put in another rebuilt unit free of charge...

As of yesterday it was snowing in NYC and my truck did not engage in 4 wheel drive. I was sliding everywhere and when i did the 4x4 high light on my dash would light up. I brought it back to the same mechanic and we put it on the lift. When you put the car into drive and let go of the brake only the rear wheels spin. He then accelerated and at around 25-30 mph the front wheels started to accelerate also. I found this wierd and told him that the transfer case was no good. He told me otherwise and hence why i am here.

If the rear wheels are spinning and it takes the truck to get to 25 mph to get the front wheels spinning is this a transfer case internal issue? Meaning is the actual mechanics of the transfer case at fault? thanks

You need to check for power on the brown wire, the one that goes to the electromagnet in the clutch pack. See if it is getting power. It should have power in 4hi and 4lo.

If no power, trace back to the TOD relay.

TOD relay? So it's most likely a electric issue? I just want to make sure it's not the actual transfer case...

Thanks for the reply... Will check out the wire thanks
