speed sensor?
My brother has a 97 150 that has a speed sensor on the transfer case on the bottom of the sensor there is a gear.Does anyone know where i can get a after market gear for it.Hopefully that will help get his speedometer back close to normal he has 35in tires and 4.56 gears.thanks

All it is is a gear at the end of the sensor that looks alot like a distributer gear and from what ive found out so far is for every 3 mph your truck is off you loose a tooth.Now what i dont know is what speed that its measured at since the faster you go the more its off i just cant seem to find one for 4.56s ive only found them up to 4.10s and thats at steeda.com.
Its Comin Right for us!

97 up read the same as my 94 Ford as all 92-96 F150's do witha PSOM. Speedometer is driven off of the rear axle. If I'm wrong...wow. Speedo isn't supposed to have been T-case driven since 92. And I'll be really pissed if they went BACK to T-case setups.

Speedo feed comes off the ABS tone ring in the rear diff as an electronic signal, it's been this way since 1992. The speedometer can be recalibrated by the dealer if it is only a few mph off, I think up to a 35 inch tire -- the gears in the diff don't matter anymore, it is tire size.
