Possibly has a bad wheel speed sensor or has a problem with the ABS control module and/or pump. Need to have the ABS codes pulled by a service center. Also, some auto parts stores can pull codes and may be able to pull ABS codes.

SOURCE: after replacing the left front wheel bearing on a 2003 ford focus, the abs and traction warning light stay on

The bearings on the wheels has to be installed one way only, the rotor ring is built into the bearing and if installed the wrong way round the sensor cant pick up the wheel speed causing the ligt to be switched on in the cluster. The diagnostic equipment should pick this up as a fault once the car has been driven, it will see the sensor when you do the diagnostic if the car is standing still but once the car is moving and no signal is send from that wheel it would register a fault into the memory of the PCM that you would be able to retrieve later.
There is a way for you to test the sensor yourself by using a multimeter set on volts, you jack the vehicle up at that wheel, install a vehicle stand to support the vehicle to be safe, disconect the wheel speed sensor and probe the two wires into the sensor, spin the wheel by hand and a small amount of current will be produced meaning the the sensor is working and the wheel bearing is installed the correct way, you can also do a continuaty test on the sensor by switching the multimeter onto ohms, but be very carefull, if this sensor has three wires you cant do the continuaty test because of the integrated circuit in the sensor, the three wire sensors opperate on a voltage from 5Volt and it would be destroyed by the multimeter opperating on 9Volt.
If the continuaty test passes and the bearing is installed the correct way, the most comon fault would be a break in the wiring leading to the PCM
Hope this will be helpfull.

What could be the problem when I hear grinding in the front end mostly when turning, Abs light is on, AWD lock light periodically flashes, and advtrac will not turn on?


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.

Front tire shakes when stepping on brake pedal


Front brake rotors can warp in heavy use. When it becomes warped it'll cause the steering wheel to shake when brakes are applied.-----------------------------------------------------------------------------

Front passenger brake is pulsing and there is no abs light on in my 1997 pontiac grand prix.I believe it might be abs sensor but don't know where to find it in wheel assembly.


A front brake pulsing with no ABS light is a rotor that is no longer true i.e warped. Pull off the tire and rotate the rotor. Hold a straight edge (ruler) across the outside of the rotor as your rotating the rotor. You will note that it changes distance on the straight edge / ruler as it rotates. (in out wobble) A good way to test for an out of true rotor is to drive at about 45 miles and hour and really stand on the brakes (do not lock them up) If the steering wheel and or brake pedal pulsate... you most likely have a rotor problem. If your rotor has never been "turned" it is probably time to do so.

The ABS sensor is behind the rotor on the lower control arm pointed outward toward the rotor with a flat button face. You can not see the button face with the rotor installed. If the sensor is bad you will have an ABS light. I think your troubleshooting the wrong problem. i.e rotor vs your current focus of the ABS sensor.

I would like some feed back on the running dynamic on the road brake test.

2003 Merc Mountaineer AWD Grinding coming from left front tire. Tires, brakes, rotors all less than a year old, could it be a hub/bearing assembly or something different? Thanks in advance.


Hi and welcome to FixYa!
Looks like a wheel bearing issue. If the wheel bearing is worn out you can expect a grinding sound. Wheel bearing replacement is strongly recommended.

Hope this helps and thank you for using FixYa! Have a good one!

My 2003 mercury mountaineer ABS light is staying on. manually, the brakes work however they shimmy.changed the brake pads,checked the brake fluid and ABS fuse,bud when changing the pads,did now clean the...


I replaced the hub bearing assembly on drivers side twice and the light stayed on and the brakes worked fine. It was the wires (visible just above the tire on the frame) that rubbed against the frame that had shorted out. It was simply repaired and clip-stripped up out of the way. The light has been off every since then.

Is there any special tools required to change front wheel bearing on 2003 mini


you will need a big socket to remove the axle nut--about 20 mm or so. Other than that, I don't think so. Procedures from autozone.com below. it doesn't mention having to press bearing into hub.


Removal & Installation

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Remove or disconnect the following:

    Front wheels Hub nut Brake caliper Rotor ABS sensor Wheel hub from steering knuckle and driveshaft Wheel bearings
To install:
  1. Install or connect the following:

    Wheel bearing into hub Wheel hub to steering knuckle and driveshaft; torque bolts to 41 ft. lbs. (56 Nm) ABS sensor; torque to 6 ft. lbs. (8 Nm) Brake rotor and caliper New flanged hub nut; torque to 134 ft. lbs. (182 Nm)

Drivers side wheel bearing what do i need to do to replace it myself


Front - Remove tire, then remove brake caliper and caliper braket, remove brake rotor, some times will have little clips, remove clips, if they break ok, won't used them again, if 4X4 remove center axle nut, disconnect ABS harness, on back side of bearing, there will be three bolt's that hold hub bearing assembly, remove bolts, bearing should slide out, some time with a little help from a hammer, and your done , reverse to install new hub bearing assembly, just make sure that ABS harness is in same location that old one was when putting bearing in.

ABS light on a 2004 Mercury Mountaineer. How do I fix it?


Go to Autozone or Oreillys and see if they have a scanner for the ABS system. They usually scan for free.
The ABS will measure braking problems and things like worn brake linings and debris on wheel sensors.
You would want to verify the code light and then have the lining visually inspected.
There can be problems with the emergency brakes which require the rear rotors to be removed from the vehicle. Some of the rotors are a problem to remove because of rust.

When i drive my mountaineer it feels like my brakes are locked up and my abs and awd lights are on i unplugged the awd fuse but didnt help and also when i turn left i hear clicking and clanking


you should visually inspect the wheel sensors, You need to have the ABS scanned... also, a collapsed brake hose can appear to be fine externally, you need to remove it to see if fluid flows throught it and back... the clicking can be a worn outer CV joint, make sure the boot is in tact, and hasn't expelled grease, the can also set your ABS since the LH sensor or reluctor (pick up ring) could be contaminated with grease ans road debris.

'03 Merc Mountaineer humming noise when turning


If same tires as before & air pressure set correctly, or as usual, a humming when swerving, or turning one way or the other or both, it's usually a pretty good indicator.
