Are you sure that your 698 isn't just needing a bit of adjustment? The 'table is suspended by the springs which are fixed to the subchassis using wingnuts. The wingnuts are used to level the 'table.
At any rate the springs are attached to their towers from the bottom of the plinth; you will have to remove the subchassis to replace any of them. Its been too many years since I serviced one of these but removing a spring should be fairly straightforward.
