I'm having the same problems on my 2003 expedition . I just had my front two tires changed recently; Now my A4WD , Hi or Lo is grinding and pulling to the right when I accelerate, feels like the front end of my truck is falling apart. But it works fine in 2wheel hi , so thats what I driving in now; till I figure this thing out about what the hell!!! went wrong to the point where no one knows what happen in that Very short period of time. Do I have to buy a new hub for both sides or just the (IWE) SOLENOID ? what would be your best suggestion at this point?

Your problem may be the new tires. How old were the rears? The diameters need to be very close because the A4WD and beyond utilize the wheel rpms to determine if there is wheel slip. A larger (new) tire rotates less than an older more worn tire, the A4WD sees that as wheel slip and engages. I bet the shop suggested you do all 4 tires didn't they? They were not over selling you, they know the deal. 4Hi and 4Lo couple all the wheels together, but with different diameters the fronts and rears are trying to turn different rpms, hence the noise. 2 more new tires will fix your issue.

I have a 1988 expedition with 180,000 miles. It runs like a tank usually. Today after returning from a 20 mile trip to the office I arrived home to find I needed to go out to pick up dinner. I started the truck and started down the road only to hear a grinding noise and felt the truck lurch forward. I pulled over and started out again same result. The dash light shows 4x4 low but the switch isn't set in 4 wheel mode. Any ideas?

Sounds like the a4wd is engaging. Did you try running it through the 4wd selections, i.e. put it in 4 hi, then 4 lo? See if that gets it back to where it belongs. Your '98 has A4wd and no 2wd drive, correct?

My 98 has 2H A4WD 4H and 4L. I haven't had it out of 2H in over a year. Tried switching through 4W modes no change still have light saying 4x4 Low Range.

Could this be the electronic shift motor? Can I test to prove its not working?

Yes, but usually the failure is that it doesn't engage, not that it randomly does. Not sure how you would go about fooling it into disengaging. Did you try 4x4 just before this happened?

The solenoid is what would send the impulse to the motor to move. If you didn't switch it, there is no reason for it to be in 4WD. Are you still driving it?
The motor is a plug and play and unbolts pretty easliy. You could take it out and see if there is anything going on.
