Differential & Gearbox Rebuild Options
We rebuild gearboxes and differentials across a wide range of vehicles, including 4WDs, utes, and light commercial fleets. Our process begins with thorough testing and teardown to identify worn or damaged internal parts.
From there, we clean housing, check tolerances, and rebuild using OE or upgraded components depending on your vehicle’s needs. We can also adjust backlash, re-shim gears, and reseal housings to the manufacturer’s spec. If you’ve noticed oil leaks, vibrations or gear whine, don’t wait—early action can prevent full failure, improve fuel economy and save you from more costly damage down the line.

Frequently Asked Questions
What’s the difference between a gearbox & a differential?
The gearbox (or transmission) controls how power is delivered from the engine to the wheels by adjusting gear ratios based on speed and load. The differential (or diff) allows the wheels to rotate at different speeds when turning, improving traction and handling. While both are part of the drivetrain, the gearbox manages speed and torque, and the diff distributes that torque to the wheels. Each component has unique servicing and rebuild needs, especially in high-use or heavy-load vehicles.
When does a gearbox or diff need to be rebuilt?
A rebuild is often needed when components are worn, damaged or failing due to age, poor lubrication, or high-stress driving. Signs include noisy operation, difficulty shifting gears, slipping transmission, whining or grinding sounds, vibration during acceleration, and fluid leaks. If caught early, partial repairs may be possible, but severe wear or internal damage usually requires a full rebuild to restore performance and reliability.
What’s involved in a gearbox or differential rebuild?
A rebuild includes disassembling the unit, cleaning all components, replacing worn or damaged gears, bearings, seals and gaskets, and reassembling the unit to factory specifications. In some cases, upgraded parts may be used for durability. The process also involves precise adjustments to ensure correct tolerances and smooth operation. Rebuilds are a cost-effective alternative to full replacement and can significantly extend the life of your drivetrain.
