Abs light on wheels shaking - 2003 Mercury Mountaineer

It sounds like you have a warped rotor. when you brake it shakes the wheel and throws the abs sensor at the wheel assembly and turns your abs on because it thinks that you are locking them up. Replace rotors and pads and it will solve the issue

Sounds like ABS, Is your ABS light on or Brake light?

bad tire, gad wheel bearings , loose steering tie rod ball joints , wheel alignment
take it to a front end specialist for a full inspection

YEP BAD WHEEL BEARING WILL MAKE A ROARING LIKE NOISE WHILE IN MOTION.BAD WHEEL COULD PUT DRAG ON WHEEL WHICH CAUSE ABS LIGHT TO COME ON.YOUR WHEEL BEARING HAS THE WHEEL SPEED SENSOR BUILT INTO IT.SO IF WHEEL BEARING BAD THE WHEEL SPEED SENSOR PART OF ABS BRAKE SYSTEM WILL CAUSE ABS LIGHT TO COME ON IF WHEEL BEARING BAD.MAKE SURE FRONT BRAKE PADS INSTALLED CORRECTLY IF NOT. YOU WILL GET TERRIBLE WHEEL NOISE ALSO.

Most likely when the ABS light is on,the system is turned off,don't know

I would go over the brakes real good, as I have zero faith in professional repairs,and then work on the ABS Code
Most likely a Wheel Speed Sensor

OK, when the ABS module is unplugged, the same results. That tells me that the ABS system is not working properly.
Did they look into the master cylinder and other abs related components?
Any ABS codes on it?

If steering wheel shakes above 50 mph that's likely to be the tires on it, rather than a brake problem.

Have tires balanced and rotated and inspected for out of roundness that might cause vibration above 50 mph.

i would start with checking the axles because most of them have a abs ring on them which will trigger the abs light. also make sure your axles are in good shape. last resort would be that you need new tires because the steel bands inside are starting to seperate. good luck

check the battery ,check and replace wheel bearings,check replace wires and fuses.

you might have a wheel bearing coming apart,most lickly in the frt which would cause the abs to come on,or it just be a fluke that it is shaking due to a warped rotor,i would jack up the rfrt on each side and see if there is any play in the wheel bearing by shaking the wheel up and down.

I doubt it. You'd have an ABS light on. All wheel are warm to scalding hot after even light driving. ABS systems do not apply brakes. They unapply them. They simply cut the fluid to one of the wheels / axle sets of brakes. (Newer stability control systems use the brakes) In your case. The ABS can deactivate either front wheel independantly, or the both the rear brakes together. You can take the wheel off & flip the pad & piston up to check it if you want, but I wouldn't think it was the brake dragging at the top of my list, no.
