speedometer problem
I have a 88 f250 extended cab 4x4 diesel with a manual trans. The speedometer stopped working awhile back and im just getting around to working on it. I pulled the cable out this morning and it wasnt broke and in good shape. Also, i pulled the gear mechanism out of the transfer case. It looked like it was in good shape and worked right. The plastic gear looked good. What have i missed? What else could it be?

I know the clip your talking about, and yes it,s plugged in all the way. I had trouble putting it back together with that clip, so i just put some wire through the holes. It worked good. I cant figure out why its not turning that cable

The plastic nylon gears in the transfer case could look ok but it could have a small dip in them... Did the needle bounce as it was quiting? And if the gears are fine them the cable could be broken internally... A way to test it is remove the nylon gear put the end of the cable (the part that turns) into a drill and spin it... Can't remember which direction though

Just went out and took it off. It could be worn enough to keep it from catching with the gear in the transfer case. Ill call around and try to find one. Ill keep you posted

both gears are available from the dealer, if i remember correctly they are around $5 each. there is one on the cable, and one in the transfer case. usually it is the one in the t-case that goes bad.

On your bw1356 its not difficult, pull the rear yoke, then 4 bolts and the tail housing can come off. This will expose the gear. there is a spring collar between it and the case, pull it off with your fingers, slide the gear towards the case pull the metal ball out of the shaft that is now visible, then the gear can be slid rearward off the shaft and the new one can go on in reverse order.
