I have a 2002 Sable. When the front wheels are both raised off the ground by gripping the front and back of the front tires and moving in and out I get a very slight amount of play. The ball joints and tierod ends are not loose or showing any slack. The slack seems to be in the rack and pinion gearbox. my question is if there is a way to adjust the gearbox for slack as on lder vehicles? also are the tie rods removable from the gear box and replaceable without removing the gearbox? Oriellies has tie rods that show to screw on to the gearbox, with a balljoint at the end nearest the gear box. Is there a way to know if it is the tie rod ball joints gone bad, or the gear box itself? car has about 127,000 miles.
