2004 Chevy Tahoe V8 Four Wheel Drive Automatic 64000 miles
While driving my 04' 5.3L Tahoe around town in 2 wheel drive I have no problems. Then, once in a while the car on its own switches normally to 4low (4wheel drive low) and my dash reads " service 4x4.&Quot;
I've replaced the " sensor" about 2 years ago at the dealors prompting and now its doing it again. It should be noted that we never use the 4x4 feature either.
I then have trouble getting the car to move back into 2 wheel drive and when I do the 3 buttons (2, 4H, 4L) go dark.
Today when this happened, put it in Neutral and switched it back to 2wheel drive and there was a very loud scraping sound.
That doesn't sound like a sensor. What should I be worried about?
