    My DB 990 serial number 990/A/449771 (1961 ) is leaking oil from the nearside rear wheel.
    Where is the oil seal ??????
    I have taken off the wheel, undone the six bolts that I thought held the hub in, but the hub will not come out, I have taken off the large back plate to reveal a large gear that is held in with a locknut and washer, but no seal.
    What next please ?????????????

  5. Yes large nut has to come off and the bull gear then hub and shaft will pull out
    When you get the new seal if there is a wear ring around the shaft you can either get a collar made or chop spring down slightly in the seal to nip it tighter
    Hopefully you should be ok not doing any of the above but just a thought
    And fill the hubs with a 140 oil
