Should i have grease on front ABS sensor? (1 Viewer)

[rc51kid]

I had been getting ABS code 32 intermittently. That is front left sensor. So i pulled it, cleaned it and the electrical contacts. It was covered in thick grease. I just cant remember from when i did my Birfield where the seals, grease and ABS sensors all sit. Should the grease be in the same area as the ABS sensor or are the supposed to be separate?

Yes, the sensor end sits inside the knuckle housing, everything normal there.

I have a similar question for the rear - toyota dealer did an inspection for me on my new-to-me LC, and now I have a squeaking from the rear - pulled it apart yesterday to look, and ABS sensor is sparkling clean, and looks like it may be touching the ring - is that normal? If so, I assume it and the ring should be covered in grease?

Not that anyone answered my question, but for anyone else searching, the ABS sensor wasn't the source of my squeak. the metal retaining tab on the caliper was bent up and contacting the rim - I suspect it was done "accidentally on purpose" by the dealer as a way to bring back unsuspecting people for more business - which of course has failed miserably in my case as they won't get another dollar of mine.

So in short, the ABS sensor/ring can be dry - not sure if it's supposed to be, but it doesn't seem to hurt anything.

Its been a day or two since I tore my front and rears apart, but if I recall correctly....the front sensors (as mentioned above) are located directly in the knuckle and exposed to the birfield grease in the closed knuckle while the rear sensors are kinda set up like a domestic axle whereas the sensor detects the reluctor wheel behind the rotor hat in a dry fashion. Or in my case a disgusting muddy and silty fashion.....

Typically they are not malicious. If you do not trust them find a replacement.
