Differential Pinion for the Land Rover-type axle differential.

The pinion gear runs on the differential cross-shaft inside the diff carrier, meshing with the axle sun gears to drive both half-shafts while allowing the road wheels to turn at different speeds through corners. Suits the four-pinion differential fitted to the 10-spline axle.

Frequently asked questions

What does the 599944 differential pinion do?
The 599944 differential pinion is a gear that runs on the differential cross-shaft inside the diff carrier. It meshes with the axle sun gears to drive both half-shafts while letting the wheels turn at different speeds through corners. It suits the four-pinion, 10-spline Land Rover-type axle.
Which Land Rovers does this pinion fit?
This pinion fits the 10-spline Land Rover-type axle used on the Defender 1987-2006, Range Rover Classic, Discovery 1, and late Series 3. It's the four-pinion differential gear, so confirm your axle is the 10-spline type before ordering.
How do I know if I need the 10-spline differential pinion?
This pinion fits the 10-spline Land Rover-type axle, the earlier differential design. Later axles typically use a 24-spline setup with different gears, so the two aren't interchangeable. Count the splines on your half-shaft or check your axle type before ordering.
What causes a differential pinion to fail?
A differential pinion typically fails from shock loading, low or contaminated axle oil, or hard off-road use. Worn pinion and sun gears usually cause whining, clunking on drive take-up, or play in the axle. Running a damaged pinion can go on to wreck the whole differential.
