on top of the rear diff, toward the driveshaft. it's under the brackets.

 

rite on. thanks. im checkin mine tomro

 

Just wondering what makes them go bad? This might be apples to oranges, but my wifes 01 Explorer had this sensor go bad and it had a ton of gunk on it. When I wiped it off most of it is metal, wear from the gears and parts of the dif. Could all this metal throw it off or is that what makes it go bad. And yes I know this axle isn't long for life, it had a bad axle seal got low on oil, I added over a quart. The ABS light issue is how I found the problem.

 

should i undo the brackets do clean it off? or can i just spray some cleaner around the area?

 

/\/\/\/\/\ as he said you really cant just clean it and expect it to be ok. if ur lucky it might work for a little while but you will need to replace it for a permanent fix

 

i have heard of gunk building up on them and a cleaning working. i would just replace it for the effort. mine broke when i removed it anyway, so without a spare i would have been sunk. it goes into the pumpkin, so spraying, at any rate, would not clean the vital part.
