Hello All
My 1985 300td's speedometer jumps all around when I first starting rolling cold until I get up to about 10MPH - after which it works perfectly. After it begins working well it doesn't jump anymore even below 10MPH.

I'm hoping this is a lubrication problem with the cable.

My question is: What is the best way to lubricate it? Should I disconnect it at the cluster and drip oil on the end? Or should I disconnect it at the trans and withdraw the cable from the housing and put oil or grease on it?

Thanks, Joseph
