Rear wheel bearing hub replacement on a 2002 pontiac grand prix

Remove tire. Look for 4 bolts behind the brake housing

Hi, the wheel speed sensor and tone ring are built into the bearing/hub assembly. Make sure the new hub contains an ABS wheel sensor and the cable was properly connected. If it is properly connected, the new hub may be defective.

Good Evening, these days it is a whole hub assembly and is held in by three bolts after you remove your caliper and rotor and then the nut off of the cv axle, then you can remove your hub assy bolts. One Note be sure to pay attention to the position of your ABS wire if your car has antilock brakes as to put it back in the same position. And keep safety in mind if you do it yourself.

Its a bad wheel speed sensor. It is built into the hub. If you did not have the problem prior you probably damaged the sensor in the new hub. Unfortunatley that means replacing it again. You need to have someone scan the vehicle while driving it to see if it is in fact that one or another just happen to go out. the scanner must have gm data listing.

the rear hub and wheel bearing assembly is sealed-for-life and must be replaced as a unit. it is secured to the knuckle w/ 4 bolts. then maneuver it out through the brake caliper bracket.

YOU HAVE TO CHANGE THE ASSM. SORRY

Hello! It sounds as if you have a wheel speed sensor that is failing. The wheel speed sensor calculates the wheel/tire revolutions and sends this information to the speedometer, which then displays that information as MPH/KPH. On 97-06 Grand Prix's this and the ABS sensor are the same module, and in order to replace, you must replace the entire hub assembly. Here is a view of the hub assembly from the back side of the hub/wheel assembly. You may want to inspect the sensor wires for any fraying, loose connections, etc.



Hope this helps. Thanks for using FixYa!

has to be scanned with the computer to find out what is cause the abs to shut down and the shut down trac control! could be a defect hub bearing ! if it was off for three day then came back on. sounds like it anyway! do assume it's good because you got it new! good luck

Either someone damaged a sensor for the ABS/TRAC control, or the replacement parts are not compatible with the ABS system.
