I am going to swap out the M5OD tranny for a ZF, possibly out of an 89 F-250 I possibly might buy. The 89 also has a 10.25 rear end on it that I want to swap in my F-150. I have a 8.8 axle in my F-150, which uses the sensor on the top of the differential for it's ABS control as well as the speedometer. The 89 uses the cable operated speedo, so it doesn't use a speed sensor in the rear axle, but it does use the ABS sensor in the rear axle. I'm wondering if that ABS sensor on the older 10.25, still puts out the right signal so I am able to use that sensor as an ABS and speed sensor on my 95 F-150. So basically, I want to know if the ABS sensor on the 10.25 can still be used as a ABS/speed sensor in the newer truck. The sensor is basically a magnet...it's so simple I assume it'll work and be a plug/play deal....but I'm hoping for confirmation. Anyone have any info?

 

I have 88 and 95 Ford manuals and will check in am -- will have to find 88 manuals. Will get back.

 

It will work, but the only issue that comes to mind is the tone ring in the diff has the same number of teeth per revolution. The sensor itself is exactly the same and will work fine.

 

As above everything I looked at in books appears same including output test 650mv at 5 mph. Resistance between 900 to 2500 ohms. If output is same at 5 mph no. of teeth is probably adjusted for 1" plus difference in ring gear size.

 

Excellent. I'm gonna put that 10.25 in the rear of my truck then.
