    Balances the whole wheel and hub as a unit. Always worked, my model Nissan was apparently notorious for being hard to balance with Cooper tyres.

    If the wheel was correctly balanced it means that the problem must be in the hub assembly, go figure. I never found out why, but it just worked.

    You may need to ask around a couple of places, it was not a tool they used eyery day.

    Yeah wow. I want to see that done!

    How many kms have the shocks done and how hard a life have they had? What's the wheel alignment like?

    Was the balance done using a finger balance or just the normal clamped against the face? Were the wheels removed from the balance m/c then remounted to check that they were still showing as in balance? Had that problem with my D4 when the tyre shop's machine was too worn.

    Good questions re the balancing procedure. I'll ask them.
    Hard to say re the work the shocks have done other than towing something heavy enough to need an electric trailer brake (second owner) but they'd be original with 188000 kms on them.

    I don't know how to post a YouTube link for sure.

    If that link doesn't work.

    Search "on car wheel balancing" although it's Yankee it is the same machine my shop used.

    Regards

    So I tried two different links and they both worked, can't believe my luck.

    Should your problem be in the suspension, this will not be a solution but it will be a cheap way of eliminating your rotating mass as the source of the problem.

    Used to get 'on car balancing' back in the 70's. It's nothing new.

    Basically it says there's something wrong somewhere!

    My guess is that the shocks are way past needing replacing so I would replace them then see if there's still a problem.

    Thanks and absolutely - as you and Ytt105 say, something's wrong and it'd be helpful in sorting it out. Obviously it'd have to be done every time there was a wheel rotation or the spare was put on (though I can't even track it to one corner at the moment!).

    Thanks too Graeme, the shocks are moving up the list

    Gotta love a maintenance catch up schedule that's starting to resemble a light restoration job!

    I haven't found anyone willing to do the on car balancing thing, most are very dismissive.

    I have had the rear struts and one of the front replaced with no change in the shuddering.

    Have the rims been swapped front to rear to check the effect? If a rim is out of round it may balance OK but hopefully the operator would have commented. However as the rims/tyres are quite wide, being only slightly out of round might be enough to cause the vibration on your vehicle.
