    Perentie 6x6 rear axle & AVM hubs

    Hi
    Since fitting the avm hubs on the rear axle they have leaked.

    I understand there are 3 seals, an axle seal, inner hub & outer hub. Are the hub bearings greased or lubricated by the diff oil?

    Thanks
    Bob

    Greased wheel bearings Bob. Good luck stopping those AVM hubs from leaking. I have tried bigger o rings but after a while even they start leaking - a bad design sealing arrangement. I have taken mine off until I can get around to designing a better seal.

    Thanks Brian
    Looks like I need to replace the axle seal (RTC5992). Contacted dealer and they are list $508 each? Ouch. Even with new axle seals can you still expect to get any oil at the outer end of the axle?
    Re the AVM hubs I pulled one down and I’m guessing the seal in there on the selector knob is just to stop dirt and water getting in and were not designed to keep oil in.

    I think there is the possibility I could machine up an aluminium knob and fit a double o ring to seal it if there is going to be oil at the hub.

    There seems to be a small amount of oil that gets past the inner seals Bob. Those seals are ridiculously expensive and not a really good seal. If you succeed in making a new knob with alum, I would be interested in a pair as well.

    John Craddock have the seals for 25 gbp each so have grabbed 2 and see what they are like. will start looking at the new knobs on the weekend.

    Brian, if I can get a revised knob sorted, happy to make an extra set for you to test

    Appreciate if you can post up a pic when you get them Bob. Hopefully they are an improvement on the originals.

    Work in progress

    Hi all
    Sorry for the delay, work was super crazy heading up to Christmas.

    Seals turned up from craddocks, I think they are new old stock. Given the design, I Cant see that the felt seal can stop oil transferring up to the hub.

    So off to the garage and came up with a new switch. Haven't bothered to put in the new axle seals as I want to see how the new switches perform. Only done 45 minutes but no leaks yet (touch wood)

    Regards
    Bob
