This is common when the ABS wheel speed sensor goes out to see which one this video and guide can help you.

The video showed me how to get the codes which made me replace the right front hub and sensor. All fixed!

The traction control light and abs light are coming on all the time. Just before the car stops, the brake pedal vibrates as if the abs is engaged. This stops at times and the warning lights go out?

What sounds like is happening is one of the wheel speed sensors is dropping in and and out intermittently. The pedal vibration your feeling is the ABS system actually activating because one of the sensors is reading inaccurately and the ABS computer reads that as a brake lockup and the system activates to release that wheel. You will actually need a professional scan tool that has the ability to take frame by frame snapshots of the ABS data to determine which sensor is doing it.

Where to begin? I can not help with the traction light, but it should be nothing to worry about if it is not blinking. There are numorous sensors for you ABS and if all are not right your ABS will not work, but you will be alright with out then as long as the light does not start to blink, ir it does get to a sevise station ASAP! As far as your brake not working good you should check the fluid or better yet just get then seviced. It should not cost you much and you can buy your own parts and have them installed, the installer will not garuntee them but the place you bought them from will. Now to the loss of power. You may be due for a tune up. When was the last time you changed your air filter, plugs, and maybe even your wires? These things do not cost much and even if you have to take it in to get serviced it is still cheaper than a new car. At 126k you still have a lot of life left in your car if you take care of it. If you tell me what has been done to your car I can help with ither things that could be te loss of power problem, like clogged fuel filter. PS, if ou do change your air filter go to advanced and get a K&N, you will get more power and save on gas.

Saturday I got my wheel bearing fix on my car because it felt my tires were about to come off, and my abs light was on then.I thought that once I got my wheel bearings done that the light would go out, but it didnt. The person who fix my car also told me that I needed my rotors, and my front brakes replace badly, and that my rotors were thining out. But my tire stills make that noise like the tire is about to come off when im stopping on the brakes.I brought one new tire today for the front, and I need another for the other side. Im not for sure what is going on. I thought the noise would stop one I got the wheel bearings fix, but is didnt, and the abs light is still on. Please tell me what is your outlook on the problem. Please

Inspect rotors for warpage and pads for thickness.

The ABS light is most likely a wheel sensor, but only a chassis scanner will give you a code. Most garages have one.

How do you replace a front passenger hub assembly, my abs light is on because of a speed sensor inside of the assembly, where can I find information to replace the assembly?

Jack up the wheel to remove it, remove the axle nut and cotter pin. There are three bolts to remove, then tap and pry on the assembly to remove it from the spindle. Looking at the new one will show you where the bolts are.

When you install the new bearing, it is critical that you use a click-type torque wrench to tighten the axle nut. A typical value is from 180 - 240 foot pounds. Use the value listed on the instruction sheet that comes with the new bearing assembly. If you put the vehicle's weight on the wheel anytime the axle nut is not tightened to specs, the bearing will become permanently noisy.

As a point of interest, a lot of these GM replacement bearings cost considerably less with the ABS sensor installed. They can be used for replacements on non-ABS equipped cars at a lower cost than the bearings without the sensor. Weird, huh?

My traction and ABS light comes on after I release the brake pedal after starting the car. I've had the wheel sensors tested and they all all OK. I did replace the front one because it didnt look good with the wires. Still have the problem. When the lights are on the traction on/off button doesnt even work. Someone told me it could be the motor for the traction. Playing this guessing game is expensive. Can someone give me some reliable imformation about this problem?

Thanks
Desiree

Hello, I'm Danny
You will need to use a code reader or scanner that supports abs and traction control systems to find out what the stored fault codes are in your vehicles computer. Here is a tutorial showing what is involved. Here is a tutorial for you to view as well on how abs- anti lock brake system codes are retrieved, checked, and erased.

Once you perform this, Get back to us with all the code information and we can then properly diagnose the issues on your vehicle. Hope this helps and thanks for using 2CarPros.
