Sounds like a CV joint or a ripped CV boot or possibly an axle bearing

Call the dealership. I seem to remember that Pontiac had a recall for this problem just recently where the antilock brake system would lock op and the system caused people to get into accidents. This is a manufacture defect

SOURCE: 2002 Pontiac Aztek - AWD disable light and Anti Lock Light

AWD disabled from a sensor unit in rear differential that senses high temp. This thing is over $300. Whine is from fluid. Need to change fluid. This versatrack fluid is about $40 per bottle and you need 3 bottles. Thumping noise is from loose rear knuckle bushings. These are part of the entire rear knuckle assy. and you must replace complete knuckle.

SOURCE: my anti lock light , awd disable

Hello! Did you make sure that the plug is fully seated and the sensor harness wires aren't damaged? Also - if the light came on and that is what prompted the change - you'll need to get the trouble code reset. Any major auto parts dealer can do this for you - free of charge.


Thanks for using FixYa!

SOURCE: awd disable and anti lock

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.

How do i get info on any recalls on my 2004 pont aztec & how do i get in contact with somebody about anti-lock & awd problems


Hi! Matt, Most likely if the anti-lock brake light and the awd disable light come on at the same time a wheel bearing / wheel speed sensor assembly is faulty.Listen for a humming noise when driving and try to determine where it is coming from(left/right/front/ back) or any looseness/play in any wheel. That's the possible bearing/wheel speed sensor causing the problem. Or have the abs system scanned to determine which wheel sensor is reading incorrectly.If the awd disable light is off then the awd system should be funtioning.

Awd disable light and anti lock light on


It could be a wheel bearing as the speed sensor for the abs is located in the bearing

Clunking and whinning when locked in awd


check the cv joints for wear. check rear drive shaft for worn slip joint splines and "u" joint wear. When you lock in awd there is no centre diff to allow the variations between the wheels and so you are experiencing a torque build up between the front and rear diffs . This put stress on the entire drive chain so any looseness or worn parts will display noises. Remember that the awd lock should be only used on surfaces that allow the tyres to slip and relieve the stress ( dirt road---snow---mud--ice )
