Hard to turn when frontend on ground only and turns like power steering when raised up on jack. Whether frontend raised up on jack or down on the ground: have 1/8-1/4 steering wheel turn play before sector shafts start to engage; sector shafts/pitman arms/drag links/tie rods/spindles all connected together without looseness and movement is smooth. Replaced upper steering shaft bearing 9 years ago because steering shaft was moving up/down in column tube when turned. The play seems to be between the double sector shaft and ballnut and/or inside the ballnut. Has anyone got different ideas on something like this or how to isolate what the problem source is? Any help would be appreciated.
