This is an hour glass steering box I assume, have you checked the thrust bearings and end float in both the column and the drop arm, is the plain bearing on the drop arm in good shape? Are you over meshing the worm, if you slightly release the adjustment do you solve the problem? Stationary and under the weight of the car any steering box will be a little heavy but even just rolling along this should largely disappear.
