Grease Your Speedometer Cable | ||||||||||||||||||||||||||||||
Introduction | ||||||||||||||||||||||||||||||
If you hear a squeeking or "chirping" noise from your dash while your car is in motion and your speedometer needle bounces instead of sweeping smoothly and holding a steady reading, chances are, your speedometer cable needs lubrication. I have done my best to describe the procedure here. Please be aware, it is possible this procedure will NOT cure your speedo problems since the bearings in the speedo head itself *can* wear out - in this case, greasing the speedo cable will not solve the problem, you will need to have the speedo head rebuilt or replaced. In *most* cases, a noisy or jumpy speedometer is cured by greasing the cable.
OBJECTIVE: To eliminate a noisy and bouncing speedometer by lubricating the speedometer drive cable. |

**Remember where everything went! and don't lose those screws! **The cable should have some of the original grease still on it so be careful what you let the cable touch - speedo cable grease does not come off of interiors very easily! It's a good idea to put a small dab of speedo cable grease on the very tip of the cable - this will make it easier to reconnect the speedo to the cable. Wipe any large globs of grease off the end of the cable and jacket as this will just end up dripping down inside your instrument cluster. *** NOTE: On most of the turbo Buicks, the speedometer drive cable is in two sections. BOTH SECTIONS MUST BE GREASED! If you have an older car (pre-86 maybe??) with cruise control, one section of the cable will run from the transmission up to the cruse control module under the hood. The other section goes from the cruise control module, through the firewall to the speedo. The later cruise control modules work off of a signal from the ECM so the speedo cable does not connect to them. The cable is still in two sections. The sections are connected together directly in front of the windsheild wiper motor under the hood. Once you have located this connection, continue to step #9. That's it! Time for a test drive!
