On my 300cd, the OE cable caused enough bounce on the speedometer needle that the cruise would surge due to the needle bounce. Last winter in very cold conditions it started to scream so I replaced it.

The first run with the cable and it was perfect - no bounce in the speedometer from barely rolling on up. The next day, it screamed when driving over 55.

It's all about the speedometer cable routing, the speedometer is great. It's just dangerous to adjust while moving, and inconsistent. Yesterday I got it to be real smooth and perfect from 25mph up. I can live with that - let's me run cruise control on the highway. Was perfect through when I pulled up my driveway yesterday. This morning, as soon as I backed out, bouncing was severe at all speeds. Even when I adjust it and it smooths out, after a little while it will get bouncy again.

I made sure not to overtighten the cable to the speedo...

What am I missing? Very frustrated. Would like to put kickpanel back...

Thanks!
