The horn on mine took all of five minutes to replace. I got whatever Amazon said was the loudest. I was hoping for “poop your pants” loud but it’s nowhere close.2012 Tacoma base model. Have 199k miles on it with very few issues until a few weeks ago. I kept putting off the vibration coming from the drive shaft and so a unjoint gave out and sheared the yoke. I finished putting a whole new driveshaft in today. The horn quit working a while back and I need to fix that for registration purposes.
