    Speedometer Rattle

    The speedometer on my restored 1964 Falcon rattled as though the new cable needed to be dry-lubed. The rattle became intermittent but did not disappear. Now the indicator is stuck at 40mph, and the rattle is gone. This appears to be a problem with the mechanism behind the speedometer and not the cable.  I would like to hear from any MS member who has had a similar problem. I would like to replace the mechanism and not the entire instrument cluster. The mechanism might be the same between a 1964-1/2 to 1965 Mustang and my 1964 Falcon. If the mechanism is similar, I might be able to swap out the assembly 
    The suggestion concerning the type of lubrication would help the rattle but won't fix the stuck-at-40 needle.

    Dis-connect the cable housing and see if the needle drops to zero.....
    That'll tell ya if its the mechanism or the cable. (I'm voting the cable is pinched some where.....

    Re: Speedometer Rattle

    I agree with 6sally6 - the rattle most likely was either because the cable was too long or was in a bend that was too tight somewhere.  Don't spend money and time you don't have to - troubleshoot the issue (as suggested above) and find the real problem. :-)

    Will do and will report. I will pull it from the tranny end, because it is easier.
