I just want to make sure that my non-functioning speedometer problem is caused by what I think it is before I go buy a new $23 VSS... I took my VSS out of the transfer case and spun the gear with a drill, and the speedo did not work. Then I removed the speedo cable from the VSS and spun the cable with a drill, and my speedo worked. I looked inside of the VSS and the hole that accepts the cable is round, while the cable itself (at least the 2" or so of it that I could pull out of the black casing) is square. I am guessing that the female connection in the VSS has gotten worn with time and now is so circular that it no longer makes contact with the cable. I forced the cable back in and drove the truck and the speedo worked for just a bit before it dropped back to zero again and stopped working. Basically... Is that female connection in the VSS supposed to be square or circular? If it is actually supposed to be circular, I guess I just did not get the cable seated well enough and will go try again.
