ok so my 96 3.4 has been making a loud sound in the morning that comes from about right behind the left side of the cluster. it only happens when the truck is below about 40 degree's and is the loudest on mornings below freezing. once the truck warms up all the way, "I have been driving for about 15-20 minutes" it goes away it is accompanied by my speedo needle wiggling around in a 5MPH up or down, it jumps around whole time. then the noise stopes and it calms down back to normal. if I don't leave until the afternoon it never does it. any and all Ideas welcome!! I would love to get it fixed
my current idea is that the speedo cable needs some oil! how would I go about adding it? and where is the cable on this truck?
