Regular Posts: 62 | So, when I bought the car, the speedo cable was disconnected. The cable is good and turns like it should. I reconnected the cable and the speedo needle didn't move, but the whole dome vibrated slightly and made a slight grinding noise at 5-10mph. Anybody have any ideas? Any advice on pulling the dome?
Thansks! | ||

You can unscrew the cap and see if your lucky enough that the wick follows out with the cap. Most probably the wick is hardened by old oil and needs to be pryed out with a small pin. It's better to pull the complete speedometer, but it's a lot of work; - Start with removing the steering wheel - Remove the chromed ribbed bezel between the steering wheel and the AstraDome - Now loosen the four nuts that holds the chromed crescent with the four switches – note, just loosen them somewhat - Remove the two nuts that holds the brushed aluminum crescent cover (around the AstraDome) - Remove the two Philips screws under the chromed crescent with the four switches - Remove all the contacts from the gauges - Remove the speedometer cable, the indicators and high beam lamp holders - Remove the 4 screws that holds the globe to the speedometer - Now carefully lift out the globe with the gauge clusters - Remove the 4 screws that holds the speedometer to the dash panel - Lift out the speedometer. Once that you have the speedometer out, you could try to work it free with an electric drill/driver and a square bit - carefully turning left and right with the torque set very low. Use sewing machine oil and wash out the old oil with new. Then, of course, if you have a speedo-shop close by, that would be the best option. They can check and repair it for you. At the same time, check all EL-lamps so that you could repair them as well when the AstraDome is out. http://www.forwardlook.net/forums/forums/thread-view.asp?tid=23457&... is electro&highlightmode=1#M497209 | ||

Regular Posts: 62 | Thanks! Where is the cap to unscrew for the wick? I am assuming under the dash in the rear of the speedo? | ||

Elite Veteran Posts: 1102 Location: Hayward, Calif | I've found lubing the speedo cable as the 1st thing to do. I usually use white grease generously as I'm feeding the cable back into the housing. I have found this to cure a lot of noisy speedo's and it's the easiest thing to do. If this doesn't cure the noise, then go on to the speedo head. Jerry | ||
