Re: speedo lube
I have a '31 roadster. I may just be imagining things, but I believe (hope?) my speedometer cable is getting lubricated from my periodically pumping grease into the universal joint housing. I remove one of the speedo cap bolts and pump the grease in until it starts coming out of the bolt hole and give it a few more good, fast pumps. I would think that the churning action of the universal and the softening/liquifying of some of the grease on a hot day, long drive, works some grease into the cable. The spinning action of the cable in its sleeve then distributes the grease on up the cable assembly.
I do know that after a universal lube job and a few miles of driving I see excess grease oozing out around the cable attachment nut at the universal housing and through the cable sleeve a little distance up the cable. The grease is definitely getting into the cable.
All I know is that in the 25 years I've owned and driven the car I've never had any speedo cable noise or other speedometer functional issues.
for what it's worth...
