Advance trac, abs, 4x4
I had same issue at 100k miles exactly. I had noticed a slight grinding at right front wheel a few months prior when I turn hard right. Thought it was stock tires rubbing, but was not. Then one day advance trac light, abs and 4x4 high started flashing all at same time. I nearly crapped my pants. This issue at highway speed can kill you! The very thing designed to prevent roll over will also cause it. Main culprit is the abs speed sensors which control all three things. Might as well do both sides at same time. Also found that my hubs and bearings were bad so changed those too. A good, but cheap mechanic this is a $700-900 fix. Do it urself for less than $400, but do both sides. This seems to be a common thing as well as the crappy transmissions they put in these trucks.
