Rear/Front Differential Gear Set (Replacement)

This differential gear set is a key drivetrain spare part used to split engine torque between the left and right wheels while still allowing them to rotate at different speeds in corners. 🚗⚙️ Without this action, the tires would scrub, the vehicle would fight turns, and the axle components would suffer heavy stress.

Why this part is needed

Inside the differential housing, gears transfer power from the ring gear to the axle shafts. This set keeps traction smooth on bends, reduces tire wear, and protects CV joints, axle bearings, and the final drive from shock loads.

How it works

When driving straight, both wheels share torque evenly. During a turn, the internal gears allow the outside wheel to spin faster while the inside wheel spins slower, keeping the car stable and predictable. ✅

What happens if it’s worn or broken

Common symptoms include whining/howling under load, clunking on acceleration, vibration, metal flakes in oil, and poor cornering feel. If ignored, teeth can chip and seize the differential, possibly locking a wheel and damaging the axle or gearbox. 🔧

Technician tip

Always replace with correct backlash setup, fresh gear oil, and inspect bearings and seals during installation for long service life.
