Do you have sloppy steering in your Cavalier or Impala? The cause could be your Chevy steering rack. As the major component in the now ubiquitous rack and pinion steering system, the Chevy steering rack takes input from the steering wheel and turns it into side-to-side motion to move your front wheels. The name Chevy steering rack is a little misleading, too: The Chevy steering rack actually contains the pinion, the power control unit, and various other bits and pieces, especially if you have power steering. Not only does a power Chevy steering rack have to contain all the forces involved in turning your vehicle, but the power Chevy steering rack also has to contain hydraulic fluid under tremendous pressure. Combine that with about 80,000 miles and you frequently end up with a leaky, marginally effective Chevy steering rack. And if you think you'll just ignore your leaking Chevy steering rack, prepare to be surprised one day in the not too distant future. That fluid leaking from your Chevy steering rack is also the fluid that helps you turn the wheels with ease. As the Chevy steering rack leak grows worse and worse, less pressure is available to assist you in turning. Eventually, you get no pressure at all and your power Chevy steering rack instantly becomes a manual Chevy steering rack. The moral of this story is get your Chevy steering rack checked if you have a leak. Don't worry-many times it's simply a hose that's loosened up and you won't need a new Chevy steering rack. But even if you do need a new Chevy steering rack, the time to find out about it is while it's up on the rack at your favorite shop, not while you're doing 70 on the interstate.
