Not a task I relish doing, there's so little space to work in behind there. Made worse by the floor and pedals getting in the way.
Still, it was worth it. I lubricated the speedometer cable and the speedometer mechanism itself- didn't realize there's a little felt pad under a tiny freeze plug looking piece. Oiled that up and that's now 60 by my GPS, accurate enough for this.
Disassembled the bulb that was in the tachometer and rebuilt it with some parts of another of the dash bulbs that had a failed segment.
Tested and working.
Means the whole dash is now the same color when the lights are switched on.
The plugs are good but I had forgotten that the sleeve was trash.
So, I got happy with the hones.
Result? Not a huge difference. The reverse blocker still doesn't work which is a telltale in the book. Going try get a replacement, then I can break the pin that holds it all together and take it to bits.
Pulled the driveline apart. Looked like the original seal, not a great design to begin with but as years of wear and some cnut enjoying an entire tube of rtv in the gap to try seal it up- which didn't work- it was time for replacement.
Better neoprene seal, took it for a drive and it's dry now. Now that's fixed it's got a date with the pressure washer.
