Ok so can a failing diff nose bearing be lubricated?

Not looking to do anything dodgy like quieten it down a bit to sell it, it’s just a case of a knackered bearing, no money and a 60 mile daily commute at the moment, need to eek a bit more life out of it till o can afford to take it down to Bell engineering for a diff swap.

is it accessible at all from an external point of view?

Lubrication of a worn bearing can't hurt but not sure how you would physically do that? Landrover - turning owners into mechanics since 1948

All lubrication happens internally when moving (rotating) and there is no way to lubricate it from exterior.

Oil is flung under centrifugal force to the diff bearings. This is one area that the Freel2 to is very poor, compared to more conventional shaped diffs.

However if the bearing is making a noise, then replacing it is the only option. Hyundai Ioniq 5 Ultimate. The family car.

The pinion bearing is splash lubricated by the ring gear.

If you want to make sure that your bearing is always submerged in oil then park with the front Tyres lower than the rear Tyres.


My driveway is steep, if I reverse into it my LR2 will be at an angle as described.



For mine I bought a magnetic drain plug to collect the particles. (but the noise wasn't loud)


Note: others have tried to do this when the bearing is really loud and they were not successful.



Good luck

Hi, I had a noisy diff repaired, but I still think it was a wheel bearing, as the bearings were not too bad. I have run Jaguars for many miles with noisy Diffs. with no failures. I have seen a collapsed F2 rear pinion bearing, it trashes the lot, including the case. So check the wheel bearings as well. I would check you have oil in the diff. housing, then reverse up a pair of ramps to push the oil forward, then see if it is still noisy. I always put EP90 Hypoid oil in a diff. You can then smell if you have a leaking seal! As I get older and deafer cars run longer between repairs, as I can only hear failure when it gets bad. Its worth checking the Bevel Box oil as well, often forgotten.

Best regards, Paul
