Well the last 6 months my speedo usually wasnt reading anything under 25 miles an hour now it kinda floats around wherever till i get to about 50.. is the sensor in the rear end or tranny? and how much of a pain is it cus frankly ill run the thing off my tach for a speed reading for all i care just curious what the fix entails

 

My speedo died when the ABS sensor on the diff went bad. I've heard there is supposed to be one on the tranny tailshaft but I didn't see one on mine.
