I tried (unsuccessfully I think) to get "oil" to flow into either end (ZF or speedo)of the 3 year old replacement, shielded cable.
I then (maybe or maybe not) got some WD-40 into the speedo end.
What I also did was re-route the cable under the dash...with much gentler curves.
The results were amazing...95% quieter and an almost imperceptible pulsing at low speeds which smooths out above about 30-40 mph.
