possesed speed gauge

[christophbmw]

ok so this rarely ever happens but when it does it pisses me off. every now and then the speed gauge will go up and down. say if im going 60 it will go to 55 and then to 65 and back down to 55 it and goes really fast. its quit annoying. anyone with this problem?: i dont know what it is. thanks

Whoah that sounds wierd!

My speedo is 10mph off. (reads 10 over what I'm actually doing) which is quite annoying too! And I don't know why

have you cleaned or replaced the speedo plug in the differential?
A jumping speedo might be a bad plug, sensor, but I do not think it would be bad wiring, as it seems as though you are gettting a signal at all times. The speedo never drops to 0, does it?

[christophbmw]

i took out the pickup on the differential and cleaned it. and yes once it drop to zero. only for like 10 seconds though.
