Just as another reference\data point for anyone with broken clock spring (issues with horn, steering wheel controls, and \or airbag light on).
Couple of month ago I started having issue with horn working intermittently (depending on steering wheel turn angle), tested horn using alarm panic button- no issues, so I knew clock spring is going…
Purchased aftermarket one (84307-30090) for $19.99 from eBay, similar to this one:
84307-30090 FIT FOR TOYOTA 4RUNNER 2010-2016 US STOCK | eBay
And used this video as a guide:
Toyota Tacoma Gen 2 Clockspring [Clock Spring]/Spiral Cable Replacement [Airbag Light Fix] - YouTube
I did disconnect the battery, marked the steering shaft, steering wheel puller was not needed in my case; I was very careful with removing and reattaching angle sensor as well as plugin all connectors back into new clock spring -making sure all pins are aligned.
So far everything works- no problems, will see how long the aftermarket part will last. During my research I have came across only one person who mentioned that aftermarket clock spring worked 5 years for him, I guess time will tell.
My truck is 10 years old with 106K, this is a first actual repair I had to do on it (outside of maintenance\ upgrades\customization items), so with age\mileage even 4Runner will break down... unfortunately … LOL.
