Sounds like a wheel hub assembly is bad without seeing it. Alot of GM vehicles have the ABS wheel speed sensors built into the hub assemblies. Should be able to narrow the noise down by driving the car slightly turn left and right noise should change from loud to soft when turning the wheel. ( if you turn left and noise gets louder hub on right front is noisey.Opposite will occur if left side is bad)

The anti-lock light is on and it is causing the awd to disable what should I do?


If the ABS is causing the AWD to come on. Scan it and find out which wheel sensor/bearing is bad, replace it. This could happen. Most AWD lights are because the sensor/actuator in the rear axle assembly is bad. A high dollar part.

My brakes seem to make a loud vibration sound when I barely apply them, it's like the anit-lock braking sound when you hit ice but the roads are completely dry. I had the brakes looked at but they


reset the ERCM using a scan tool
while the brake pads looked fine , the rotors should be removed as that gives the same impression as the abs in operation
there could be a cracked rotor causing the noise
take it to an accredited brake specialist shop

ATI LOCK LIGHT ON BRAKES WORKING BUT DONT FEEL THE SAME AS NORMAL


Check Brake fluid level.

When the ABS light is on, the brakes should revert to standard braking.

The only time ABS should invoke is when the tires are slipping as sensed by the wheel speed sensors when the wheel locks up on any of the axles.

ANTI-LOCK BRAKE SYSTEMS General Information Fig. 1: RWAL brake system diagram

There are two basic types of anti-lock systems available for this vehicle; a Rear Wheel Anti-Lock (RWAL) brake system and 4 Wheel Anti-Lock (4WAL) brake system. The 4WAL system has two variations; a 3 sensor system and a 4 sensor system. The 2WD vehicles will be equipped with the 3 sensor system, but the AWD vehicles can be equipped with either. The systems are easily identified by looking at the rear wheels for a sensor harness. If there is a sensor harness and thus, rear wheel sensors, it is the 4 sensor system. If the vehicle is not equipped with a harness, it is the 3 sensor system. The 4 sensor system takes it speed references from each of the wheels. The 3 sensor system takes its speed references from each of the front wheels and the vehicle speed sensor located in the transmission (2WD) or the transfer case (AWD). The RWAL system components consist of the Vehicle Speed Sensor (VSS), the Electronic Control Unit (ECU), the isolation/dump valve and the Vehicle Speed Sensor Buffer (also known as the Digital Ratio Adapter). The ECU also receives signals from various brake switches. The 4WAL system components consist of the Electro-Hydraulic Control Unit (ECHU) valve (also known as the Brake Pressure Modulator Valve or BPMV), the wheel speed sensors, Vehicle Speed Sensor (VSS) on 3 sensor systems and the VSS Buffer. prev.gif next.gif

02 F 150 back trun signal and brake lights not working


After checking the fuses, try with the steering wheel column tilted all the way up, There is a connector at the base of the steering wheel column, that the truck side of the harness can get tight on, and slowly pull the connector apart.<br />Behind the knee panel is this connector. Pull it apart, and check the pins for discoloration and make sure the connector tab lock still works ( most of the time, this is the 1st thing to brake ).<br />This is it repaired with some stove wire, zip ties can also be used.<br /><img src="/uploads/images/2EAD21C.jpg" /><br />

Whot is an anti lock and where do i find it and how it repaired.? when comming to a stop the brakes seem to pulsate.


you need to take your car in to a reputable brake shop. Your rotors are likely warped causing some pulsating. The anti-lock is an automatic function that helps keep wheels from locking up under hard braking. If your ABS/Anti-Lock light is on, definitely take it to get inspected.

Having issues with my brakes.


Will probably be caused by either a wheel speed sensor or abs module fault.
