Hi My 1989 center console steering has become erratic and now attempts to tun hard left or right at the onset of each turn. We have the deck off and all is secure there. Inspection of the rack assy. at the helm also looks secure with about 8 degrees of backlash in the wheel. We also made a couple of attempts at tightening what looks like a friction control with no change in results. Our run yesterday found us limping back at idle. one would expect to find somthing loose or broken. Any ideas?
