I have recently lubricated the speedo cables on our 2 T100's and I thought it may be interesting to tell you how I did it.

It is quite an easy excercise but if you have ever done it you will know the one small problem is getting the inner cable back into the outer cable, because it tends to catch the ferrel on top of the cable where it enters the speedometer. This is how I did it.

You do not need to remove the outer cable or even undo it from the speedometer, all you need to do is undo it from the gear box on the front wheel and give it a sharp tug and it will come out, I greased it with a mixture of mollyslip grease and engine oil mixed 50/50. The trick is when you thread it back into the outer cable, push it up untill it meets the obstruction where the cable bends to go into the speedo, you will find you have a further 2" of cable to go, connect a drill to the cable and give it about half a second burst and you will find the cable goes right in no problem, when you connect the cable back onto the gear box don't overtighten the phillips screw or you may break the plastic fitting, the whole excercise takes about fifteen minutes.

Its worth giving the inner cable a good clean down before relubing, I use cheap brake cleaner and some shop rag.

Most how to grease speedo and tacho cable instructions warn against greasing the last six inches or so of inner cable (at gauge end). For fear of grease working its way into gauge.(spiral action).

I don't think so, I wish someone had explained it to me so clearly a few years ago. It bears repeating on a regular basis.

I've lubed mine a couple of times. It can be hard that last little bit. I just tapped on it & in it went. But the noise came right back. Then I removed the speedometer & droped oil on the shaft. It takes several drops a minute or 2 apart but that was my noise. The shaft not the cable. That was over a year ago. As far as putting grease up too high the cable is wound so the grease won't "thread" up, just down. Been a Chevy tech for 47 years. Lubed millions of cables. (Count 'em) One year they were built wrong & they pulled the grease right up into the speedometer. They were twisted the wrong way. We didn't have many of them but a few came in. We had to change the cable. They were universal back then so you had to cut & install the square end. PNTB.
