So my speedo needle flutters pretty bad and varies about 10mph after I reach or surpass about 30mph.

I have a 1996 4x4 drivetrain. I just got done putting a 2000 cab onto it. I retained all electrical everything from the 1996.

I have checked all grounds to be on bare metal and ground straps too.

I am going to try swapping to another cluster to see if that is the problem.

Anybody have any ideas for me to try/consider?

Interior dome light, and rear speakers are not hooked up but I don't see how that could affect it unless MORE grounding is required.

Thanks a bunch.

does the 96 have the VSS and gear in the transfer case?

check the plastic gears on the VSS and inside the t/case

Yeah it does. I'll check those when I check the resistance reading on the VSS later today. Hopefully its just the sensor but I doubt it would go bad just from sitting for 6 weeks....

Idk how it would just go bad like that either.. my gear on the VSS was worn and not making good contact to the gear inside the t/case. When I changed the gear (correcting my speedo from gear ratio swap and tire change) it stopped the fluttering.
