Ive changed the wheel bearings 3 times on front 2 times on back the awd light is on and antilock on will only run to 2500 rpms but no wheel bearing noise can u help 2005 buick rendezvous

possible a loose front wheel bearing or a failed front wheel bearing
the abs light sensor is probably touching the rotor
tack it back to the shop that did the job as there is a problem in the assembly of the unit.

You have a wheel speed sensor that is not working correctly. The ABS computer is losing the signal from the wheel speed sensor and interprets this as a wheel locking up, so it is going into antilock mode. When it does this on dry pavement when it is obvious that there is no wheel actually locking up it is called "false Antilock Mode" or "Overactive Antilock Mode". This is a pretty common problem on several vehicles.

The system on your Blazer uses wheel speed sensors which are an integral part of the front wheel bearing and hub assembly to determine wheel speed for the front wheels. It uses the Vehicle Speed Sensor (VSS) to determine rear wheel lock-up. The VSS data is shared between the Body Control Module (BCM), the Vehicle Control Module (VCM), The Powertrain Control Module (PCM), the Transfer Case Control Module (TCCM) and the Electronic Brake Control Module (EBCM - AKA "Antilock Module").
The problem is MOST LIKELY being caused by a front wheel bearing being loose (pretty common) which will require replacement of the front wheel bearing and hub assembly. However, it can also be caused by the VSS or a breakdown in communication between any of the modules that share the VSS data.

If you have either of the front wheel bearings making noise (growling or whining) then that is almost positively the cause of your problem. However, if it cannot be determined this way, the computer network will need to be scanned to find out which it is.

Hi, I can help

You have a bad wheel bearing assembly.
The bearing is starting to seize up, and it is telling computer there is a problem in ABS system, as well as AWD system.

First thing is to locate which bearing it is in the front end of the vehicle.

1)Jack up each side of the front end, place a safety support stand or jack stand under frame of vehicle.
2)Once vehicle wheel is free from ground spin the wheel and listen for grinding.
3)Compare each wheel as you spin and make your best judgment on which is more noisy.
4)This is your problem wheel you need to remember which side of the vehicle is the source of problem when ordering the part from your local auto parts store.

To repair: Remove wheel, remove brake caliper, then brake caliper bracket, then the rotor, remove center axle nut, then remove bolts for wheel bearing hub assembly.
Your ABS and AWD lights will reset themselves upon successful test drive following repair.
Let me know if you need more assistance or pictures.
Good Luck, have a great day.

awd disable is usually a $200 tube type sensor in the rear diff. abs light is usually front hub bearing

remove front wheel brakes,rotors, axle nut,remove the four bolts on the bake side of your unit bearing using one of the 4 bolts removed from the unit bearing (also knowin as wheel bearing) go get a half dozen of the same bolt only 1 to 2 inchs longer theard them into the unit bearing from the back side and start beating. the unit bearing is a sob to get out but will come out with time once you get it out pull out your axle shaft replace the ujoint and reassemble anti seize everything as you re assemble it

You have a bad hub bearing. 100% garunteed. The light is on because the bearing is so bad it hit the sensor for the abs & traction control , breaking it. So you're gonna need a bearing, a sensor,probably new brake pads,any seals{probably one} & a shop that can do it. The bearing is pressed in & needs to be pressed out. Heating & beating is not a good idea.

if you have rear abs then yes. you may have pinched the cabl attached to the wheel bearing

AWD Light is caused by your Rear Wheel Hub(s) one or both are going bad. Dealer cost is $500.00 part at Auto Zone is $129.00. Not to difficult to replace if you are some what mechaniclly knowledgable

are awd light came on a few day ago...no change in the driving behavior. just had two wheel bearings replace last year. any idea what the awd disable light means now?

Thanks,
