Professionally Reconditioned with Premium Components
Every V8 LandCruiser 3.9 ratio front differential is carefully stripped, hot-washed, and thoroughly evaluated. We rebuild these units using premium Japanese bearings and seals, ensuring the crown wheel and pinion backlash is set to precise factory tolerances. Genuine Toyota components are used where required alongside top-tier aftermarket parts to guarantee a differential capable of surviving harsh off-road tracks and heavy touring loads.
Common Differential Problems in V8 70 Series
The immense torque of the 1VD-FTV 4.5L V8 engine places massive stress on the front driveline. High-kilometre, hard-working vehicles frequently suffer from collapsed pinion bearings, chipped crown wheel teeth, excessive backlash, and oil leaks. A professionally overhauled diff centre is a much safer, long-term investment than risking an untested salvage yard unit with an unknown service history.
