Instrument Panel: Testing: Speedometer

  1. If speedometer is noisy, check for kinked, pinched or burnt casings. Check for bent cable tips, improper or insufficient lubrication of cable, or rough drive gear.
  2. If speedometer whines, driven gear stem in transmission could be binding with adapter. If calibration is incorrect, possible causes include incorrect transmission adapter, incorrect drive gear or sleeve, over or undersize tires, and faulty speedometer head.
