I’m comfortable working on cars, can’t I repair this problem myself?
Answer: Maybe. Removing the speedometer is a straightforward procedure. But working on the internal mechanics of the unit is a process that carries a much higher degree of difficulty. Most Do-It-Yourselfers will not have adequate tools or workbench equipment to perform a proper repair.
Replacing the stepper motors requires the removal of the gauge needles. The needle shaft is very delicate and easily bent or broken if improperly handled. Recalibrating the gauges correctly after the repair also requires a high level of proficiency.
The majority of car owners would be better off letting a professional handle the speedometer repair.
