About six months ago my ABS and Brake lights started to stay on
intemittantly on my 98 Dodge Dakota. Sometimes on Sometimes not.
After several months of this the lights stayed on permanently. I was
advised to change the speed ring sensor on the differential which I
did on 9/6/05 and the problem was fixed.
Last week, after only two months and about 5K miles the lights started
coming on intermittantly again. Did I miss something? Would there be
some reason for such a quick failure?

There's lots of different sensors, get the vehicle scanned and post
the results.

axle bearings are devoloping excessive play and the airgap the sensor
needs is changing so it sets the light
but it could be a bad sensor i used to change them all the time

Axle nearings? The sensor is located on the differential, nothing to do with
the axles or excessive play.

exactly my point and i have seen the diff.bearing's go bad and the tone ring
take out the sensors a couple of times out of the 100 sensors i or so i have
replaced and i can't say how many jeep grands axles bearing seals i have found
leaking after the customers complained of a abs code only to replace the
bearings and sh.t

Ok, now its the differetial bearings not the axle bearings! Wouldnt the cust be comlaining of a noise in the rear if this were the case instead of the ABS lite on?

hey frank if you had bearing play your diff would be humming along.
some dakota models have a sub harness that comes with the sensor and
should be installed between the sensor and exsisting harness. check it
out

Replacement sensor had a harness adder as I recall, but it appeared
that it was just to reorient the direction of the harness, maybe for
protection.
Thanks to all responders. I'm going to pull the differential back cap
plate and see if I can tell if all is well in there. past due for a
recommended fluid change anyway (although I normally ignore
differential changes) and i did recall that the fluid seemed a little
dirty when I changed the sensor. I thought that was strange.
