Yo Ski,

To release the speedo cable from the cluster, push the large white plastic collar down, then back.

The cable end locks automatically when you push it into the back of the speedo. Look at them while it's apart & you'll unnerstand. by Steve

Chilton; "Reach up behind the cluster and disconnect the cable by depressing the quick disconnect tab and pulling the cable away.

Remove the cable from the casing. If the cable is broken, raise the vehicle on a hoist and disconnect the cable from the transmission.

Remove the cable from the casing.

To remove the casing from the vehicle pull it through the floor pan.

To install:

To replace the cable, slide the new cable into the casing and connect it at the transmission.

Route the cable through the floor pan and position the grommet in its groove in the floor.

Push the cable onto the speedometer head."

Lubrication; This is for a Stang, but similar "...Cable function depends hugely on lubrication and plenty of it. When lubrication becomes lean, cables bind and deteriorate, which only makes the problem worse. If the cable has deteriorated to where it is frayed anywhere along its length, it's time to replace the entire cable assembly. Frayed speedometer cables damage the inside of the sheath to create two sources of binding. This is why entire cable assembly replacement is so important to smooth speedometer operation. Here's the transmission end... Here's the transmission end of a speedometer cable, which takes a #N751 o-ring and the appropriate speedometer drive gear, chosen depending on the transmission and rear axle gear. New cables are already equipped with the o-ring. The barber pole pathway carries transmission lubrication to the drive gear.When you install a new speedometer cable or service an old one, generously lubricate the cable with a mixture of transmission fluid and lightweight lithium grease. Mix up a modest *** of lithium grease and transmission fluid in the palm of your hand and run the cable through it. You can also use speedometer cable lubricant for this purpose. Run the cable back and forth until saturated with ****. Then, slip it into the cable sheath..." READ MORE by Jim at

Can the SPEEDO cable be accessed from the rear without removing the dash????

Yo,

Some say you can insert a small flat-blade ***** driver to pop it off, then the cable will just pull right out...

And, just push the plastic collar DOWN. If you look inside it, you'll see it only has 1 tooth, and it's at the bottom. That tooth hooks the groove in the back of the speedo.

Crawl under & push all the slack in the speedo cable forward, and up thru the rubber grommet in the floor/firewall.
