'03 Expedition - Message center says to get Advance Trac serviced. On a trip, 75 miles before it first began to act up, I had the right front tire balanced. What could I check myself before I turn it over to a dealer? Like maybe dirt in sensors? When it first happened, I was going straight at 65 on an Interstate. I think it was raining. I was in 2wd, but had used AWD earlier that day, maybe 140 miles earlier, while climbing a steep gravel drive to a hard road. No wheel spinning took place.
The dealer I bought from has closed. What about where I stand outside and turn the wheel lock to lock, to re-center the system? Are there connections to jump, to make this work?
