Diff Pinion Seal suitable for Toyota LandCruiser 80 Series (Front and Rear)

OSN0400 differential pinion seal suitable for the Toyota LandCruiser 80 Series. It is a 38mm x 74mm seal, 11mm to 18mm wide, and the same seal does the front and the rear diff, so one part number covers both ends.

Oil weeping from behind the pinion flange onto the tailshaft and underbody means this seal has gone. Replace it with the pinion flange off, and fit a new pinion nut. One per diff.

❓ FAQs:

Q: Front or rear diff?

Q: Do I need a new pinion flange?
A: Only if the old one is grooved where the seal runs. We list the BPF1001 pinion flange.

Q: Not sure it suits your vehicle?
A: Send us your VIN and we’ll check it before you order.
