Heavy‑Duty Differential Gear Set for Toyota Axles ⚙️

This premium ring and pinion set restores smooth power delivery and quiet operation in the rear final drive. Built from heat‑treated alloy steel, it keeps torque flowing to both wheels whether you cruise on-road or tackle tough trails. Ideal when upgrading tire size, towing, or replacing worn gears after noise or oil contamination.

Why you need it 🛠️

Worn gears cause whining, vibration, and uneven tire wear. A fresh gear set resets correct ratio and backlash, improving acceleration, fuel economy, and driveline reliability. It’s a must after bearing failure, water ingress, or off‑road shock loads.

How it works 🔧

The driveshaft spins the pinion, which meshes with the ring gear in the carrier. Tooth shape and set backlash transfer rotation at the right ratio, multiplying torque to the axles. Proper shim setup and bearing preload keep a clean contact pattern and quiet running. Use quality GL‑5 gear oil for cooling and film strength.

What happens if it breaks ❗

Expect howl on cruise/decel, clunks on take‑off, metal flakes in oil, and heat. Ignored, this leads to chipped teeth, bearing collapse, loss of traction, or even axle lockup. Replace seals, set pinion preload, verify pattern with marking compound, and perform a gentle break‑in with an early oil change.
