It was coated but it was coming off. Regardless, it's gone now.

 

The place is called Advanced Auto Care in West Sacramento California- and wow- I didn't realize the sensor was only 30bucks!- greedy

 

I just hate shops!

 

I have a 1998 dodge durango and it says the speed sensor is on the trannie not the rear diff. can i get some help on the subject.

 

there are two sensors, one on the tranny, and one on the rear diff, they usually go out together so just replace em both so you know you are good to go

 

The ABS Speed Sensor is on the axle. The Transmission Output Sensor is on the transmission (Drivers side mid way). They work hand in hand so parts stores will often mix the names of the sensors.

 

That fixed my issue woo hoo the wife is happy now

 

Great to hear and your welcome!

I have a 2001 4.7 Durango that suffered from intermittent PB & ABS lights for quite some time. Took it to Brakes plus and they diagnosed it as the ABS computer, which is apparently in short supply and very spendy (> $1,000). Well, the internet does provide good information from time to time as this thread demonstrates. Replacing the rear speed sensor worked for me. Replaced it about a 1 - 1/2 weeks ago. Went on a 2,100 mile road trip from the Denver area to Phoenix and back. No problems with the intermittent lights the enitre time. Thanks for the pictures as they really helped!
However, discovered a small leak from the rear diff speed sensor mount after getting back. Went underneath yesterday to tighten it up and ended up shearing the retention bolt at the base. BE VERY VERY CAREFUL WHEN TIGHTENING THE BOLT!!! My guess is after 10 years of use, and the stress of replacing the sensor in the first place, the bolt was weaked a bit (as I don't feel I put too much pressure trying to tighten it up). I don't have the tools to fix it so I'm taking it to the shop today to get fixed. Hope they don't have to drop the rear axel to get it done.

BTW, averaged over 18 mpg over the trip. Pretty darn good for a 10+ year old 8 cyl mid-size SUV fully loaded at 75mph.

 

Cost $48.00 to fix the bolt. Still better than taking it to the dealer for them to diagnose and replace the speed sensor.
