Professionally Reconditioned with Premium Components
Every HiLux KUN26 3.58 ADD front differential assembly undergoes an exhaustive workshop overhaul. The aluminum housing, carrier, and ADD tube assembly are stripped down, hot-washed, and checked for casing fatigue, shaft wear, or gear pitting. We rebuild these units using premium Japanese bearings and high-grade seals, resetting ring-and-pinion backlash, bearing preloads, and tooth contact patterns to exact factory specifications. Quality genuine and aftermarket components are used throughout to ensure optimal strength, leak-free seals, and quiet operation under heavy towing or off-road conditions.
Understanding the KUN26 ADD Front Differential
The Automatic Disconnecting Differential (ADD) system on N70 HiLux models uses an electro-pneumatic or electric actuator tube mounted to the front diff housing to disengage the passenger-side axle shaft in 2WD mode. Over time, hard off-road use or heavy towing causes collapsed side bearings, worn ADD sleeve splines, and pinion seal leaks. Fitting a factory-spec reconditioned ADD differential assembly provides a far more reliable, long-term solution than taking a gamble on an untested second-hand unit from a wrecking yard with unknown mileage.
