How do you change the speedometer cable in a 1991 Ford Mustang LX 5.0L 5 speed?

Answer 1

first safely put the car on jack stands then find where the cable goes into the transmission remove the bolt that retains the cable to the transmission and wiggle the cable till it comes out. For now just leave the plastic gear on the cable the cable housing has a couple of retainers one near the transmission end I think mine was on the frame of the cross member then another on the fire wall or the fender if you buy the cable and the cable housing together it should have a new rubber gromet for the fire wall if you bought just the cable you remove the retainer that holds the plastic gear on the end and set it aside for the moment" don't let dirt and grit get on your cable and into the cable housing so wipe the end off good and lay it as straight as you can out in the encompartment then comes the hard part working under the dash you have to get your hand up behind the speedometer and feel for the plastic detent retainer just at the end of the cable you have squeeze on the back of the detent and carfully pull it away from the speedometer. If you know any four letter words you may notice how that sweet mustang has turned into a whipping post for them at this time. You will probly scratch and cut your hands up just getting to the back of the odometer and most cables unless you have really looked at how the detent works to release its hold on the speedometer will give you a fit but don't give up you can do it but if you get to mad just walk away for a bit and come back to it its not worth the damage you may do to the mustang. anyway getting back to work once you get the cable loose from the speedometer pull the cable housing down just below the dash and slip the old cable out and the new cable in or pull the old housing and cable all out if you got a new one but you may want to pull the new cable houseing through the fire wall by tapeing it to the tail end of the old one and get someone to help feed it thru as you carfully pull it into the car and hook the new cable Into the back of the speedometer. It will push on very easy but be sure it is all the way on. Once you get to this point put your O ring seal on and your old gear and gear retainer rout your cable back the way it came to transmission if it don't slip in with a bit of a wiggle turn you gear a little and try again. put all retainers back in place and get the car on the ground for a test drive if by chance the speedometer don't work check to ensure you are fully plugged in at the back of the speedometer there may be a little jumpyness to the speedometer at first but as the cable lube gets spread out it will be ok.
