What is a rack and pinion?

The rack and pinion steering gear is a newer and lighter steering gear, and may be hydraulically assisted, electrically assisted or unassisted. When the steering wheel is turned, the steering gear pushes or pulls the wheels in the requested direction.

How does rack-and-pinion work?

The steering rack is located between the front wheels, and attaches them to the steering wheel. The inner and outer tie rod ends link the ends of the steering rack to the steering knuckles, which is what the car's wheels attach to. When the steering wheel is turned, the steering rack forces all of these components out on one side, and pulls them in on the other side.

What are the symptoms related to a bad steering rack?

Rack-and-pinion problems typically come with the following symptoms:

  • Power steering fluid leaks
  • A whining or clunking noise when turning the steering wheel
  • Difficulty steering at low speeds, or a loose sensation when turning the wheel

Can I drive with a steering rack problem?

Small power steering leaks won't prevent the vehicle from driving, but when fluid cannot be added quickly enough to keep the pump full, a tow truck is recommended to avoid damaging the fuel pump and steering gear.

How often do steering racks need to be replaced?

As any system that carries high pressure will, the system will eventually fail from normal wear and tear, but this should be well into the serviceable life of the vehicle. For most vehicles, the power steering system will last well over 100,000 miles before any failures occur.

Keeping the power steering fluid fresh and the system free of contaminants is key to ensuring long power steering system life. That's why sticking to your regularly scheduled maintenance, detailed in your owner's manual, is so important.
