Steering Parts and Help from AutoZone
What is a power steering rack?
The power steering system components are used to control the direction of a vehicle's motion. A power steering rack uses an engine-driven pump to supply high-pressure hydraulic fluid to the steering rack when the wheel is turned. This makes it easier to turn the steering wheel but it also requires complicated system of hoses, seals, and o-rings that contains the hydraulic fluid.
How can I tell if the power steering rack isn't working properly?
Typical problems in the steering system consist of hard steering, too much play in the steering wheel, or rattle or squeaking noises when turning the wheel. Not all problems mean there is a bad power steering rack, but if the problems are accompanied by leaking fluid, the rack may need to be replaced with a new or remanufactured unit with all new seals and gaskets.
