What Is A Power Steering Rack?

A power steering rack is an essential part of the rack and pinion mechanism of a vehicle. It describes what is essentially a metal bar with grooves on the side and a tie rod on the end. The metal bar sits parallel to the front axle and moves left and right as the steering wheel is turned. The tie rod connects to the kingpin, and movement from this kingpin directs the wheels when they turn. The steering rack’s grooves come into contact with the pinion gear, which is attached to the steering wheel via linkages. This pinion has small teeth that blend into the main rack shaft. The steering rack component transmits the steering wheel rotation inside of the car to the linear movement outside of the car. In tandem with the pinion, the rack rotates the wheels of the car as the driver turns the steering wheel.

The rack and pinion mechanism makes driving and directing your car much easier and allows you to have more control over the wheels’ direction when they turn. While this mechanism has fewer moving parts than larger conventional steering systems, it is nonetheless highly effective. The rack and pinion mechanism can operate with or without power steering, and it is the most common type of steering system found today. It exists in most cars and some small SUVs.

The power steering rack uses hydraulic pressure to allow quick and easy steering and wheel handling. If the steering wheel becomes difficult to turn, something is certainly wrong. Usually, this happens when the steering rack or gearbox builds up more heat than it should, or when there is a decrease in hydraulic pressure from the power steering unit. Sometimes, the solution to this issue is as simple as adding some fluid or making a minor adjustment. Other times, the mechanism needs replacing. Either way, it is best to get your car inspected immediately.

Driving with an overheated gearbox can have dangerous results, including fire. Therefore, it’s so important to pull over, stop the car and call a mechanic immediately after you notice this smell.
