Pull out the speedometer cable where it enters the transmission or transfer case then inspect the "driven gear" for signs of wear. Let's hope it's not the drive gear inside the tailshaft or transfer case.

 

will i need anything special to do so can someone send me an instructional video

 

Steve83 once again has some great info here: 1983 Ford Bronco Diagrams picture | SuperMotors.net

 

so if i take that piece off will it leak fluids

 

well i took the gear out and it looks brand new, so what now???

 

Look inside at the drive gear. See if it is worn. If not then you may need to lubricate the cable. I have never had the need to do this, so I really cannot help you there.

If the drive gear is worn then you have a much bigger job involving disassembling the tailshaft or transfer case.

 

i checked the little tiny gear that comes out with the cable looks brand new and the gear in the trans looks the same how do you lube the cable...
