Speedometer Noise
Hey gang,
Could use some advice on the '69. My son is finally driving it around town, and the only problem to show up so far is an intermittent noise from the speedometer. Definitely does it longer and more often at higher speeds; a vibrating/buzzing noise (no speed warning ). Noise disappears completely when we disconnect the speedo. The needle does nothing special during the noise - steady and smooth. Any thoughts/advice? Thanks...SSOW

It's a catastrophic success.

Unhook it from the tranny,pull the inner cable out of the outer sleeve,check it for wear,clean it,lubricate it,and put it back together.they gum up and get dry and it causes the to twitch going down the road.

^ No the gear drive for the speedo that goes into the tranny housing shd retain the tranny fluid (on the manual trannies anyway). I went through a simular ticking noise with a S-15 GMC I once owned, I thought it was coming from the head (on the 4 cyl.)but it turned out to be the small gear box that the speedo cable attaches to (at tranny) almost drove me bonkers figuring it out. I pulled it off cleaned it out, regreased everthing, reinstalled it and problem fixed. Doug

Thanks, guys....we'll pull, clean & lube it asap. Sure beats pulling the speedo.
I want to remember the white lithium grease as the weapon of choice in this situation. Is that right? While we're at it, does the small gear box at the tranny need to be lubed, and if so, how? SSOW

white lithium grease will do ok ,but i prefer the speedo cable lube as it does a better job and doesn't gumup it's graphite based and actually polishes the cable as it's beind used. it's available in most autoparts stores

you will get some tranny fluid leaking out on a auto trans when you remove the speedo gear.

To lube a speedometer cable, I've always just "fished" the cable into a quart of trans fluid, then pull out while lightly wiping off the excess and reinstall. I never had a problem using this method.

When I pulled my bullet out it leaked alot of fluid into a bucket I had. I think I should have jacked the rear of the truck up to keep the fluid toward the front.
