What is the power steering rack?

The steering rack is composed of a rack enclosed with a steering pinion. It's connected to the steering wheel through the set of shafts and U-joints. As the steering wheel is turned, the pinion moves and pushes the steering rack either to the left or right. The ends of the steering rack are connected to the front wheels so the steering rack inputs and turns them to the left or the right as well. 

- Common Symptoms

A failing steering rack may clunk when turning or when going over bumps.

Turning easily in one direction, but with difficulty in the other, is an indication of a problem with the steering rack.

- Common Misdiagnoses

Problems with the power steering control module (where applicable) can imitate problems with the steering rack. Be sure that the problem has been properly diagnosed before replacing an expensive steering rack.

If the power steering rack wears out badly, it will start to leak. The absence of the hydraulic fluid will result to a hard, difficult steering. This is the right time to replace a new or re-conditioned replacement steering rack. 

When the Steering Rack starts to make clunking noise each time you corner or drive over bumps, then it's time to replace this component.
