Review on APDTY Differential Actuator Assembly 2007 2016 by Kevin Abner

First of all, this part does not work with vacuum. vacuum operated, all electric. This part will also fit all 2005-2017 4WD Tacoma models regardless of engine size. Extending the warranty on them in the early years so the part was re-evaluated due to high failure rates regardless of mileage/age. The Toyota part number ending in 4 is the last part. The first one ended in 0. And if you buy this part, don't throw away the old one. Keep it with your receipt just in case. This is a factory part with a high failure rate. Remove the black plastic cover from the old part and you'll see why. The part has a low resistance to water penetration. The connection is not solid, more like the spades are straight together. Once disconnected, 4WD not working or the horrible green flashing 4WD light (quite common). The old part can be repaired as a spare if nothing is broken. Simply clean and solder the joints and lubricate with a suitable lubricant.
