Another problem to add to the list. Hopefully you experienced members can help me. Ok, Everytime I turn left my traction control kicks on, dash light comes on and it's very hard to finish turning. It happens on dry pavement. No clue where to turn for this one. No other warning lights are on. Any help on where to start would be greatly appreciated.

 

Hows the condition of your tires?

 

Tires are almost new. I was thinking maybe a bad wheel señor.

 

Could be a bad hombre.

 

That's bizarre. Sounds like bad wheel sensor but maybe not. I'll wait to see what others say. More like the differential is locking one of the halfshafts when the shaft should be turning free. Reminds me of the time my pickup got stuck in 4wd when I was our of town in dry pavement. The front diff gears ended up shattering.

 

The " very hard to finish turning" is the part that gets me. What do you mean by that, are you not able to turn the steering wheel, as if it is binding?

Are you applying the brakes at the same time when this happens or does it do this while just turning (without braking)?

I'd check the hub/CV joint on that side, some times, when they are wornout...especially lateral movement...they can move enough that the wheel sensor/tone ring gap becomes to large for them to get a consistent reading, causing the TC light to come on. Now, if you are braking at the same time and you don't get the ABS light also...that's kind of weird...because you should.

The part about it being hard to finish your turn leads me to believe the CV joint is binding or something. Do you hear a popping noise while turning?

Edit: also, if you pull the wheel sensor on that side and you see that the end of the sensor is worn away, like it's been rubbing on something...this means the CV joint on the axle has gone bad. I've seen it a hundred times, where someone pulls the sensor, sees it is worn and sticks a new one in...which usually works for a while...but it wears out rapidly...and they experience the same problem as before. One of the guys at work put four sensors on his truck before asking "why" does this keep happening...he had very aggresive tires and didn't hear the hub noise...so that didn't help matters.

When I say finishing the turn, I am trying to accelerate through the turn but TC comes on and it feels like wheel hop. I have to slow down and traction control light goes out and I can accelerate again. Only when making a sharp left turn. I know it somewhere on the right side, feels like the front wheel is hopping.

 

I have removed the abs fuse to disable the tc and will see what happens when I drive it today. I will report back.

 

Let me parse what you are saying. TC comes on, meaning the light, and you feel a wheel hop, right? What I'm picturing when you say wheel hop is a build up of tension, then the tire let's go, and the truck lurches in the direction of travel. Does that sound like what's happening? What I'm describing would result in you stopping in the turn, if you didn't keep your foot on the gas. A binding, basically. Does that describe the wheel hop situation?

I'm trying to figure out whether it is a mechanical or electronic issue. If the former, the TC light may just be acting as a warning light rather than an indicator of the cause.

 

I still have an ABS issue, but this exact thing was happening with my '03. I replaced the left speed sensor, and it stopped. I then got a right fault(prolly not applicable for you), so replaced the right side with the old left speed sensor. The TC issue of activating while turning left immediately started when turning right.
