So my rear axle had some problems.
Long story short I put a axle out of a 88 in my 92. The 10.25 works great no speedometer. Old axle has no sensor. I figured that was for rear anti lock that didn't work and light was on. So is this why speedo Inop. I am afraid I have to change this out ???

Why not just hack the two together? You just need the axle shell from the '92 axle, you can swap most of the other parts over. I'm not sure on the ring gear/carrier as to exactly what you need to get the tone ring back in there, but just the sensor and tone ring are all that's needed.

That sensor on the axle is the speed sensor for 92+ trucks. Older trucks use a speedo gear on the transmission or transfer case to drive the speedometer. You can put a '92+ axle under an older truck and just ignore the speed sensor, but I don't think you can put an older axle in a '92+ truck without some creativity.

I’d get a gps speedo unless you just have to have the dash speedo working.

ABS showed up on the 1987 F250 , but they still had a mechanical speedo cable to the cluster. 92 went to diff sensor for ALL. your 10.25 came from a 85/86 F250/F350 SRW worked fine in your 88............

Rock Auto shows one of the same sensor numbers for the 1988 and the 1992. If the sensor is a little different, going by the pictures it looks like it would fit in the same hole and mount the same way. Have you tried taking the sensor out of the old 92 rearend and putting it in the new 88 rearend and plugging it in?

Must be older no sensor. In housing. Thanks. Going to get newer housing now swap guys
