No I believe the speed ometer cable is broken.Dissconnect sppedometer cable from instrunent cluster,romove cable from back of speedometer &transmission case .romove speedometer from sppedometer cable housing if broken replace with new & make sure you grease cable when installing back in cale housing reconnect to transmission &back of speedometer.keep posting

Unscrew the speedometer cable from the side of the transmisson. Pull the cable out of the transmisson. While someone else sits in the drivers seat and looks at the speedometer you turn the end of the cable quickly. If the speedometer doesn't move the cable is faulty. Replace it
To check the speedometer only disconnect the cable from the speedometer and insert a small screwdriver.Turn the screwdriver quickly. If the speedometer doesn't move then the speedometer is faulty and must be replaced.

HI. If your speedometer needle doesn't move, or if it flutters, your speedometer cable may be bad.

To determine if it is the cable, disconnect the cable casing from the transmission and from the back of the speedometer on the instrument panel. Draw the cable out from inside of the casing. The cable looks like a twisted piece or wire. If the cable is broken or if it is dry or brittle. It probably needs to be replaced. If the cable is intact and the same length as the cable casing, the problem is likely the speedometer head.

I would also advise to check the speedometer gear as well.

The speedometer gear is located on the output shaft. Inspect it for damage.

This gear rarely suffers damage because the gear from the speedometer that meshes with it is usually made of a softer material. Sometimes, the speedometer gear on the main-shaft is replaceable. A clip can hold it in place or it can be a pressed fit. A special puller is available to pull these gears on the car.

The click you are hearing might be a dry speedometer cable. Applying grease to the inner cable will most likely help this problem. The problem is getting to the cable behind the speedometer/dash panel. You can also get to the cable from under the truck. if you crawl under the truck and look at the smaller end of the transmission, you will see the cable screwed into the tail piece of the transmission. Remove the cable from the transmission and pull the inner cable out of the outer cable. The inner cable is what spins and causes the speedometer to turn. Take regular wheel bearing grease in the palm of your hand and slid the inner cable through the grease then put the inner cable back in the outer cable. When the inner cable gets to the back of the speedometer, you will have to slowly turn the cable and give a slight pressure inward to seat the inner cable into the speedometer.

Hope this helps.

Good Luck

Replace the Speedometer Cable

1 - Remove the old speedometer cable from your car, first take off the doghouse and then the engine cover.

2 - Remove the screw underneath the dashboard and take down the steering column. This will give you access to the back of your speedometer.

3 - Take off the drive shaft bolt, and "O" ring, insert the speedometer cable through the firewall.

4 - Remove speedometer cable securing clamps from the engine compartment and on the transmission.

5 - Release the drive shaft nut from the "right angle" adapter (The nut is attached to the back of the transfer case).



Installing the Speedometer Cable

1 - Place the square end of the speedometer cable into the adapter and secure the drive shaft nut.

2 - Pull the speedometer cable through the firewall to the rear of the speedometer.

3 - Secure the "O" ring and attach the speedometer cable to the rear of the speedometer/odometer. It should be engaged in the speedometer's square hold. Tighten the drive shaft nut again.

4 - Replace the clamps that will secure the speedometer cable onto the transmission and in the engine compartment. Replace the engine cover.

5 - Drive your car slowly to be sure your speedometer is working properly. If it is, replace the doghouse. If you're stilling having problems, take the car to your mechanic.

Most cars Speedometer cable connect to one of the front wheels, but you said your speedometer sometimes stop then your steering wheel will go stiff, I think you should fix or change your speedometer cable, maybe the cable broken inside. Fix it as soon as possible for your safety.

Speedometer cable has two parts, one is outside cable, mounted and connect to both speedometer and wheel.

The other one is an inside steel cable, outside cable protects the inside cable, because the inside cable turns as soon as you move the car. It is directly connect to the wheel gears and the speedometer inside.

If your car has speedometer cable, I think you need check it right away.

Your steering wheel sometimes stiff, you also need to check your power steering fluid level, sometimes cause this kind problem.

Hope this can help you and if you have more questions, please use whatever the Fixya allowed, contact me to discuss this matter and others. Thank you.
