Wheel bearings ?

Having an issue. While on my way to west TX, my abs and traction control lights come on. And the 4 HI light is blinking. My gut tells me front wheel bearings are bad. Could I be overlooking something? I can hear some sort of noise but cant be sure. Steering seems normal.

 

It appears that the truck at times will show these codes prior to a CEL. I'd suggest you pull codes first before you start dumping money in the wrong place. My starter died and triggered a crankshaft sensor code, and I had those same lights come on, but no CEL, and my truck is 2wd....
Additionally when are you hearing noises??

 

Like I said, difficult to tell. It sounds like the front drivers side. I will see if I can pull some codes. I am also wondering if wheel speed sensor may be bad. But my gut says get ready.

 

Wheel bearing usually don't trigger code but wheel sensor does. Put one wheel on the jack and inspect if there is any play or noise.

 

I will check. Thanks.

 

If you do have to buy the hub assembly, SHOP AROUND. Rockauto.com, Amazon, yhou can literally save over $100

 

It’s likely a wheel speed sensor, wheel bearings won’t throw a code. You can jump the OBD port and your dash will light up like a xmas tree, count the sequence of blinks the ABS is throwing, its gonna be a two digit code, repeating over and over. The code will narrow down which wheel speed sensor is bad. I just had this issue and after careful inspection of the sensor, there was the tiniest amount of corrosion on one of the connector pins, I could see a greenish hue on the copper, cleaned it off and have been problem free for 6 months now.

 

Would like to thank everyone for their input. It is a bad abs sensor and front bearing is fine. New sensor should be here in a couple days. Once again thank you.
