Toyota Hilux Front Diff (ADD) Actuator

Front diff will not engage, or the 4WD light is flashing at you? Nine times out of ten it is the ADD (Automatic Disconnecting Differential) actuator. This is a quality replacement with a direct-fit housing and plug, so it is a clean swap and you are back in 4WD.

What It Does
  • Replaces the failed ADD actuator that controls front axle engagement.
  • Fixes no 4WD, flashing 4WD light and intermittent engagement when the actuator is the cause.
  • Direct bolt-on unit with OE-style electrical connector. Pre-terminated plug, no wiring mods.
  • Sealed motor and gear housing for durability.
Vehicle Fitment
  • Toyota Hilux N70, 2005 to 2015.
  • Toyota Hilux N80, 2015 to 2024.

Cross-reference part number: Toyota 41400-35034. Match it to your vehicle before ordering, or send us your VIN.

What Is Included
  • 1 x front diff (ADD) actuator assembly.

The O-ring or gasket may need to be reused or replaced. Inspect it during install.

Fitting Notes
  • Safely raise and support the vehicle, disconnect the battery.
  • Unplug the harness, remove the fasteners, check the seal condition.
  • Fit the new actuator, torque to spec, reconnect the harness.
  • Function test 2H to 4H engagement, then road test and inspect for leaks.

Water or mud ingress and a damaged diff breather can also trigger 4WD faults. Inspect the system while you are under there.

Shipping and Payment
  • Free express shipping Australia-wide, fully tracked.
  • Dispatch: in-stock orders placed before 2 PM AEST on a business day go out the same day.
  • Buy now, pay later: Afterpay, Humm, Klarna and Zip. All major credit cards accepted.
Frequently Asked Questions

Q: Is this actuator plug-and-play?
A: Yes. It bolts to the ADD housing and connects to the factory plug. Check seal condition and torque specs during install.

Q: Will this fix a flashing 4WD light?
A: If a failed actuator is the cause, replacement typically resolves the warning and restores engagement. Also check wiring, connectors and the diff breather.

Q: Does it fit both N70 and N80 Hilux?
A: Yes. It suits N70 (2005 to 2015) and N80 (2015 to 2024). If unsure, send your VIN or a photo of your current actuator.

Q: Do I need any coding or programming?
A: No coding required. Once installed, cycle 2H to 4H to confirm operation and clear any stored faults if necessary.
