Rear Differential Gear Set for Toyota Vehicles ⚙️

This premium rear final-drive gear set restores smooth power to the back wheels. It is needed when your axle howls, clunks on take‑off, or shows metal in the oil. Heavy loads, big tires, off‑road use, or high mileage can wear teeth and bearings. Replacing the set brings back quiet running, correct ratio, and reliable traction ️.

How it works

The pinion receives rotation from the driveshaft and turns the ring gear. Together they reduce speed and multiply torque to the axle shafts. Proper shims, preload, and backlash keep the tooth contact in the sweet spot. Heat‑treated gears run in gear oil for cooling and lubrication. Set up right, it delivers long life and silent operation.

What happens if it’s broken ⚠️

Worn or chipped teeth cause whining, vibration, and play in the driveline. Overheating burns oil and can seize bearings. In severe cases, you may lose drive or lock the rear axle—dangerous at speed. Extra fuel use and uneven tire wear can follow. Replace early to protect the axle housing and shafts.

Installer notes

Match ratio to front axle (4WD). Always set pinion preload, backlash, and tooth pattern. Use new bearings, crush sleeve/shims, and seals. Fill with GL‑5 gear oil and perform a gentle break‑in.
