Okay so for the umpteenth time. Change out the fluid in the front hubs. If that does not help then start looking at electrical issues. Apply 12 volts to each plug for the hub magnets and see if the wheels will lock. Work backwards from there. Don't loose heart, most issues are very easy to fix. I am betting on the hubs. As a side note most AWD will not work if the speedo does not work but if you search you can find a work around.
