I recently had a rear wheel bearing replaced as it was leaking oil quite quickly. When the shop took the bearing off the axle, the seals have "DO NOT DISMANTLE" After ringing around LR and the seal manufacturers, the conclusion was that the seal itself cannot be replaced and the bearing is actually a sealed unit, meaning the whole bearing had to be replaced. The cost was AUD1200 (USD650) just for the bearing.
Naturally I followed up on the logic of it all, and came up with this explaination: As the LR is based on a military vehicle with a heritage as long as my arm, field servicing was meant to be quick and simple. Hence the ability to quickly replace the bearing instead of repacking. Nice if you have an army quarter store behind you.
My father in law is an old retired mechanic, and mentioned that during WW2 some sort of glove was available to fit over the wheel bearings to stop sand etc. As I do a lot of sand driving in Western Australia, this sounds like a good idea, but where do you find such a thing?? |

Well, I have not had mine appart yet but I'm pretty sure the bearings get greased by the diff oil floating around in the rear axle tubes. If your rear was leaking around the bearing area, all you had to do was seal the hub. At least that's what I saw an a D90 we worked on. Only if the bearings are bad/loose do you have to replace them. But even then I would not expect them to be $650. I think you got hosed. I hope somebody can shed more light on this. |

I make it a point to repack my bearing on all four wheels about ever two or three wheeling trips. It is time consuming, but it beats having your bearings weld themselves to your stub axles. You must remember that LR seals are pretty decent about keeping grease in, but horrible about keeping dirt and mud out. |

On many models you can remove the seals which prevent the diff fluid from mixing with the hub seal grease/oil. This allows the 90wt. lubrication to move everywhere within the axle tubes and hubs/bearings which ensures that one hub does not dry out without your knowledge. I replaced rear rotors and pads over the weekend and repacked with grease. I used lots and lots of grease as I too have had a bearing weld to the stub axle. This was my only dealership visit and cost $1600, they 'replaced' everything but could show me no discarded parts to prove it..I bought the manual the same day and have never been back!! |

While I have never seen the inside of the hub on a DII, I have seen the D1, the RRC, and the Defender. And on each of those, the bearings are re-packable, and replaceable. I have also discrarded the rubbish, new oil seal that LR uses and gone to the old RTC3511 double lip seal. I used to wade my truck about 2-3 times per month in deep muddy water. I'd notice bearing issues about every 2-3 months with the original seals.
With the RTC3511, I have not had to repack or replace bearings in over 20k miles under the same driving conditions. I've noticed that Bill Davis at Great Basin Rovers also suggests this seal be used also as it offers far better protection to the hub internals.
In any event, the most expensive part in the hub assembly is the spindle, which costs about US$250. The bearings (for the D1) are US$10 at the local autoparts store. Just ask for Timken Set 37. The seal is under US$10 from any LR vendor. I'd be quite interested to know if all this has changed with the new DII.

I still have the old bearing and will take a photo once I get my camera back. The bearings are different than a D1, actually they are similar to an old rover V8 circa the 1960's.
re "That's a good point Perrone, HTF can a bearing cost $650US ??? What's it made of?" I guess when we pay the equivalent of US$26,500 for a brand new TD5 and US$25,000 for the V8, LR have to make money somehow!!! Oh the pain of it all!! LOL
PS I have a few photos of the car under Richard Morrant in the gallery if you want to see the environment we 4WD in! |
