AISIN Differential Shift Actuator P/N:SAT-011
AISIN SAT-020 rear differential lock actuator for the 2010-2020 Toyota 4Runner and other vehicles is the shift actuator assembly that operates the differential lock.
A 4WD or differential lock that will not engage or release can mean the actuator has failed. A blown fuse, a damaged wire, a faulty switch or a transfer case problem can also produce these symptoms, so trace the fault before ordering a new actuator.
This actuator is an OE manufactured direct replacement for the 2010-2020 Toyota 4Runner and the 2010-2014 Toyota FJ Cruiser.
