    Mate it ain't hard to replace seals.

    Trouble is getting that rear bearing carrier off.
    Probably coroded solid, easy does it removing those bolts, I busted one once, took several hours to drill the old one out and tap another thread

    Putting S/S bolts on the leg is a big mistake, Good one Suzuki.

    Remove the prop and the leg. Ok, thats the easy bit. Now put the leg in the boot of the car and head off to a bloody good o/b mechanic, he can fit the seals and pressure and vacume test it in about 1hr tops. I have done them a couple of times and this is by far the less stressful way. The guy I use has all the pullers to make seal removal easy and all the tools for replaceing them but most inportant is that he has the tools to PRESSURE check it and also VACUME test it. These tests confirm oil cant get out (unusual) and more common water getting in. In the past I have had the gear to pressure check but that will only confirm oil cant get out and I have had brand new seals fail the vacume test. When all test ok, take it home and refit
    cheers

    Never thought of that Blaze, thought them seals were stepped from the inside.

    Cool if there not, just wack a couple of self tappers in the old seal and pry it out.

    But your right all the same pressure, and Vac, test is the way to go and paying for around an Hours work, is good peace of mind.
