My 1978 el camino has speedo issues. It works when it wants makes noise in the cab and bounces all over when it does. I checked the connection at the Tran. And I'm not sure how tight it's supposed to be but it turns 1/4 both ways and you can wiggle it. Any ideas on what to do to fix the problem or info on how it should look. Thanks

 

The speedometer cable needs to be lubricated.

Pull the cable from the casing from the speedometer end.

Wipe the cable of all the old lube and apply fresh speedometer cable lube. Most other lubes either dry out or it works its way into the speedometer head (no good).

Lube the entire cable except for the last few inches on the speedometer end (this helps keep the lube from working it's way into the speedo head), then shove the cable back in the casing and re-assemble.

It's getting really difficult to find real speedometer cable lube. If you can't find it, you can try white Lubri-Plate. The lube can't be too stiff like axle grease or runny like oil.

 

What about the connection to the Trans. Should it be able to wiggle if you move it around. I tried to tighten the fitting but it doesn't move hardly one way or another. Sorry for the ignorance just haven't had to ever work on a speedo before

My local auto parts store had a box of ATP Parts lube. The guy behind the counter gave me a free tube and told me the box in the back had a do not re-order tag on it.

I bought all 9 tubes he had left for $1/tube. Should last me a few lifetimes.

my 1989 Camaro speedometer makes a lot of noise and the needle bounces all over the place when it goes below freezing. When warm it works great.

 

This is is. My 84 had the same problem Lubed it up and it works well now.
