Uhhh bearings I assume??? (crosses fingers)
 

So when I back out of a parking spot and put it in drive. Lo trac then trac off and abs lights come on. Until I restart the car.... so I should need new bearings soon?

But the thing is I had some pretty worn tires b4 and it was doing this after I had new tires put on its went away. Now its back.. This was like 8 months prior... so are my assumptions correct?

wheel hub

yea wheel hub .. our ABS brake sensor/ wheel bearing is all one sealed unit called the wheel hub. apparently your ABS sensor went bad.. so u need to change out the whole wheel hub. But the question is to find out which one it is.

Oh ok thanks so the abs sensor doesn't come attached to the hub all together?

Ooh nevermind u meant which one like which side right? I thought which one as in sensor or hub...

you need to find out if its the right side or the left side, someone said that you can jack the car up and try to wiggle the wheel and you will find out which ones it is if one of them has play in it and the other doesnt

You'll need to check both sensors electrically. More info here:

Well if you can get your hands on a snap-on brand scanner, they got a abs reader code in it. And it tells you what side is bad.

Same with a GM tech2 scanner.

i've got the same problem bub,

I posted before about a "slip" in driving due to the sensor acting up. My car will hesitate in certain instances and almost feel like the tranny is slipping, then the abs and trac off chime and it's fine. Like the sensor is trying to communicate the wrong wheel speed and slow it down too much

hey i have the problem where it feels as if the tranny is slipping but the lights dont ever come on then... i always think its the tranny hope its not tho...
