539706 – Inner Pinion Bearing

Fits Land Rover Differential | Available in TIMKEN or Allmakes/Britpart

Keep your driveline running smooth and quiet with a fresh inner pinion bearing. The 539706 supports the pinion gear inside your differential — a worn-out bearing here leads to howling noises, vibration, and eventually a cooked gear set.

Choose from Aftermarket Allmakes/Britpart for solid value or go with TIMKEN for premium OE quality and long-term reliability.

Frequently Asked Questions:

Q: Should I replace both pinion bearings at once?
A: Yes. We recommend replacing both inner and outer pinion bearings during a rebuild to ensure even wear and proper preload.

Q: Is TIMKEN worth the extra cost?
A: Absolutely — TIMKEN is OE on many Land Rovers, and their bearings are trusted in racing and industrial use. Perfect for serious rebuilds.

Q: Do I need special tools?
A: A bearing puller and press are recommended. You’ll also need to reset pinion preload and check gear mesh after install.
