My Speedometer is not working. HELP !!
Hi , First of all I LOVE this site . I have learned alot .It's GREAT !!! O.K. I have a 1991 F-150 XL 4X4 5 speed and since I bought it the speedpmeter doesn't work. I was told it might be the speeedo gear(yellow) but I took it out of the transfer case and it looks fine.I have read a couple of posts reguarding speedometer problems and I was a little cofused so I am asking for help. I read that if you take the gear out of the transfer case and put your finger in there you should feel the gear that it matches up with and you should NOT be able to spin it with your finger. Well I stuck my finger in there and I could ,from what I can tell, spin something. I did the drill test and the speedo works up front, so I would assume the gear is not spinning the gear inside the transfer case. My question is, How do I get at that inside gear ? What is that gear called? Is it a job I can do myself ? Could it be something else? How much would this gear cost? Any help would be greatly appreciated and again this site is GREAT !! Thanks, Dave

not quite sure on transfer cases...kinda new to this 4 wheel drive thing...but on normal automatic tranny's the speedo gear usually runs off the output shaft that drives the driveshaft. i just looked it up in the book and the speedo gear rides on the output shaft on the transfer cases as well... so it could be possible that your gear is just stripped out. But you would have to pull the transfer case and take it apart to get to it. Hope that helps!

you dont have to pull the tranfer case just drop the driveshaft take off theyoke and pull the sea then the gear just slides off of the output shaft its not splined or anything it just is pinched between the bearing and the yoke so make sure you get the yoke tight when you put it back on
