Rack and pinion steering may sound daunting, so it might help to remember its basic purpose: when you turn your steering wheel, gears turn inside the power steering rack that then turn your front wheels left or right. When components in the rack wear out over time, your ability to safely steer could be negatively affected. The good news is that replacing your rack and pinion is a job any DIYer can tackle with some time and the right tools.
