    Default GS driveshaft removal and replacement

    I recently became the second owner of a 1974 GS (sedan) and Iím currently tidying up a few bits and pieces prior to taking it for a decent run.

    The query that prompts this post is removal and refitting the driveshafts, as all but one driveshaft boot has seen better days. I suspect the inner boots are originals.

    I have actually removed both driveshafts and am contemplating refitting. When I removed the shafts, each triax joint came apart as I manoeuvred the inner section through the opening in the front subframe.

    My question is: should it be possible to fit the diff end of the reassembled shaft through the opening in the front subframe? I have, of course, depressurised the hydraulic system, temporarily reassembled the hub to the upper and lower suspension arms and jacked up the outer end of the lower arm. The challenge is to maximise the upward movement of the upper suspension arm to maximise the effective opening through the front subframe.

    Amongst the parts Iím waiting on is a new set of suspension bump stops. Theoretically, if I remove the lower bump stop prior to reinstalling each driveshaft it should allow a bit more upward movement of the front suspension arms, but in doing so can I put undue pressure on any part of the suspension cylinder?

    Needless to say, I hope replacement of the reassembled driveshaft doesnít necessitate removal of the upper suspension arm pivot pin!

    Iíd welcome relevant advice.

    Chris, it's not easy, but it's doable! Persevere. I've just been down this road over the past six months or so.

    I found that removing the bump stops on both sides gave me just enough room to weasel the inner joint through the hole provided. (While holding the inner joint from behind to prevent discombobulation)

    I jacked the opposite side to the one I was removing and relied on the anti roll bar to lift the upper arm of the operating side up as far as it could go. I can't see that this will cause any grief to the suspension cylinders.

    Bonne Chance, Pottsy.

    Thank you, Pottsy and Ken.

    I shall also add the GS Driveshaft questions thread to my collection of GS resources.

    So good to see that Mum's old car has now come full circle back to its original owner! I hope Michael enjoys it for many more years!

    I too spotted that article a couple of weeks ago - following which I enjoyed a brief email exchange with the author.

    My 'new' GS was also delivered to its former owner overseas - in Paris - and after spending some time in Europe and the UK, was brought back to Adelaide. Its owner worked near the university campus where I was a post-graduate student in the mid-70s and I admired it almost on a daily basis.

    Fast forward some 45 years and I've been fortunate enough to purchase the car and have thoroughly enjoyed my brief experience with it to date. 'It' doesn't sound quite right alongside Pottsy's GiSelle; perhaps I'll be inspired to call mine something more endearing in due course!

    Yes, the story of Michael's car going full circle is heart warming to say the least.
    Gerry and his parents were obviously excellent custodians.
    As an aside, I purchased the Stash of parts from Michael and many of them have assisted GiSelle to be as good as she can be.

    Cheers, Pottsy.

    There was an excellent motor in that stash!

    And it's securely squirrelled away against the day when I may need it!

    Michael took some of the stuff North with the car, I bought the remainder. That was one hell of a load for the C5 wagon, but it all fitted!

    Cheers, Pottsy

    I see a front panel badge has either been moved across or doubled up. No surprises there being many connections with his car here!

    sorry for sending this thread sideways.

    Well spotted! Those '1220 Club' badges were always on the car when Mum owned it!

    Well spotted! Those '1220 Club' badges were always on it when Mum owned it. But here is a pic of the first time we saw it at a Cit do held at Caulfield Race Course. 'Voila' no badges except on the rear. One can only conclude that they were fitted by A.O. Duttons before we collected the car.
    Cheers Gerry
