Richard, You are correct, the steering column should not move around when the adjustment knob is tightened down. What I have seen a few times is under the dash, where the knob and bolt go thru the sliders, there are a couple of small rectangular type flat washers with tabs on them that run up and down inside the slots in the sliders. If someone has loosened the adjustment knob too far, these flat washers can slip out of place and the tabs can turn sideways. If this happens, when you tighten the knob back up the washers and tabs do not put the correct pressure on the steering column and sliders and the steering assembly will be loose and move around, just like yours is doing. Climb under the dash and take a look to see if these parts are out of place. If so, just realign and everything should work correctly again. Marty [Non-text portions of this message have been removed]
