no speedometer or odometer!?

Don't overlook the speed sensor in the rear axle housing.. Right up top.. One 10 mm bolt holds it in and real inexpensive, about $15.00. I have seen these sensors lead to inoperative speedo's and strange shift patters along with the ABS lamp illuminated.
Just my thoughts.
Good Luck!!

FordMasterTech,
Thanks for your help!!!
I ordered an OSS sensor because I had removed it an saw some fine metal on it and crack across the epoxy. This is the forward OSS on the tail shaft. Put the new one in and still the speedo quicks after a mile
I also noticed there is another OSS behind the 4x4 shift motor, so I put the sensor there since I was getting a 720 code. Same crap. The 720 clearly points to the OSS
So I'm now after waiting for the sensor and it still not working.
I recalled your post, and took out the sensor from the rear axle. It was coated with some fine metal. Cleaned it off and the speedo now works! Well at least for the last 25 miles.

Same thing is happening to me, but with a twist
I have been having the same problems with my 1995 f150 4x4. The odometer stops working, the speedometer stops working, and the O/D light flashes.
but here is my twist. I noticed a while back (when the speedo and odo worked) that if I turned on my interior lights the odo, speedo stopped working and the O/D light blinked. Even opening the glove compartment would kill it!
I then realized that when I open my door with no key in the ignition that the interior lights did not come on!
My one uncle thinks it has something to do with the module that would dim the interior lights after a few seconds.
To me it definately appears to be wiring issue.
Any ideas??
