Re: front differential hub!

The first question is has the front hub ever been serviced and how many hours are on it, Are you running the stock front end fluid because of the way the front hub is designed it must run the factory fluid for it, it is a special fluid for only this front hub, There is a solenoid that is engaged and puts the front end lock on, This is done buy giving it 11.8 to 12 volts in the front end and the use of some plastic  parts. if the solenoid does not receive the correct voltage to engage the front end will not lock, When the solenoid is not plugged into the harness it should read 22.8 to 25.2 ohms at the connector, This is a little complicated and you need to start from one end and work to the insides, Start with the fluid change and run it for a while, Test the solenoid and make sure it is working, Make sure that the solenoid gets the signal from forward to reverse, I would do this by putting a meter on the wiring that goes to the solenoid and put in reverse and hit the all wheel drive button and see if voltage is getting there and repeat the same steps in forward gear, Remember that the all wheel drive is not on constantly and is only on when the rear wheels are slipping, the solenoid is not continuous duty, if this all checks out it may be something broken in the front differential, When it falls out of all wheel drive the part that works the locker must be disengaging and can you make it go to lock buy turning the switch on off and on again?.
