abs activates at slow stops
I have a 1999 ranger 4x4 , when I'm going to a slow final stop the abs kicks in ,dos'ent do it everytime , there's no abs warning light , took it to the ford dealer they scanned it and said it was the left front hub & bearing assembly, said the senser was'nt reading the back of the bearing assembly . I can't understand way the abs light is'nt on , is there anyway to clean that ,they want to replace the hub & bearing $510.00 ,Is a use hub & bearing replacement a good way to go? They told me I could pull the fuse and kill the abs ,but I find three fuses I pull aII three and got a speed senser check engine code . I hate to replace that hub & bearing when there's no problem with the bearing ,Is there any way to disactivate the abs ,by the way it's 4 wheel abs . THANKS 1999 FORD RANGER 4X4 4.0

I have the same problem with the same symptoms but have not diagnosed yet to determine if it is the front or rear. See my related thread below. If the sensor in the front wheel is bad, the hub assembly must be replaced (about $250 for parts). If the rear sensor is the problem, then the sensor can be replaced for about $10.

Just change the abs sensor the problem will be fixed. I had the exact same problem with my 99 4X4 I had the sensor changed (about 150$ parts and labour) the whole hub assemblly did not need to be changed. A year latter the other side started same fix.

well, I pulled the 30 amp fuse thats in the fuse box under the hood, use my owners manuel to find it, it must control the front sensor, for now I have brakes without abs, I have a abs light now to look at, but no abs actavation at slow stops,If you think of trying this don't pull the big 50amp fuse or the 10amp in the drivers door compartment ,I got a check engine light ,speed sensor malfuction , when I PULLED ALL 3, I found a use hub & bearing assbly. but not sure if I'll change it , brian931 said it was the sensor on his , did you get abs warning light on your truck ,I DID'NT have a light on mine,till I pulled the fuse, ford say,s it,s the hub & bearing ,sensor reads something on the hub I don't know thanks for your reply.

I dont know if the 99 is different than my '96. There is a 'Tone Ring' that is pressed on the back of the brake rotor. The ABS sensor sits within a few thous of that and 'reads' the tone ring. The sensor is not that expensive, but they can rust into place and be a real hassle to remove. Mine came out in pieces with great difficulty.
I can't see why you need to replace the hub & bearings if you only need a sensor. Just repack the bearings if they are good.

Hello,
If you have an up to date scanner, it should tell you which wheel it is not recieving a signal from.

Hello,
I have this exact same issue on my '96 4x4 4WABS. I suspected the sensor before I started reading this because I just had front and back brakes replaced (along with front rotors and rear drums - they were warped, a common problem apparently). In addition, the Front Right bearing was replaced (someone locked one hub and I drove around a while before I noticed.....). So all this makes me think it is maybe the sensor, because I doubt they replaced those, just the rotors.
And yes, the '96 rotors have the same ABS "tone" ring on the back of them. I couldn't believe the hassle I went through before getting the right ones! The NAPA guy finally went out to the shop with 5 sets because they couldn't determine which were correct!
So if anyone has an answer to this - does replacing the sensor fix the issue? - I would appreciate it. I plan on looking for dust, etc, but the guys that replaced the rotors are usually pretty good about cleaning stuff up after.
I am at the same point as some of these other peps - disabling the front system......

Your mechanic likely damaged one of the front sensors when replacing the rotors. It is pretty delicate. If the sensor is damaged, replacing it should fix the problem. A special scanner can read the codes to identify which sensor is bad. You should get your brake guy to make the repair. If you disconnect it, the ABS light on the dash will stay on all the time.

Thanks, that is definitely a possibility (damage during the other work). The rotors are heavy and hard to handle. I don't have a diagnostic device, but because they changed the bearing - right side - I would suspect that sensor first. From what I understand the sensors themselves are not real expensive. I would take it back to the guys that worked on it, but they are pretty good and I am something like 95% sure they were not working before, which means they actually fixed something there and didn't bill me for it :-)
And FYI - pretty sure I don't have a dash light for that, I don't remember ever seeing one on.

Free fix
Had the same problem on my 96 Bronco. Tone ring on the passenger side was CAKED in what looked like brake dust and dried grease (much less so on driver side). Used a putty knife to GENTLY scrape off the crud, then sprayed it all down with brake cleaner. Also cleaned the sensor and took one swipe on it with brake cleaner on a paper towel. Fixed the problem. Hope this helps.
