Power Steering Rack Parts
A feature that nearly any BMW owner cannot live without is power steering. If you have ever driven or owned a car without power steering, you know the amount of effort that when into turning at corners. Thanks to technology that has developed over the years, BMW has implemented several systems to make steering a car easier and more comfortable. And, nearly every BMW owner will agree that BMW has succeeded in every step of the way.
One feat of technological ingenuity is the BMW Active Steering system. In this system, the planetary gear set is integrated into the steering column. An electric motor located in the joint has the job of adjusting the front wheels’ steering angle in the proportion of the BMW’s traveling speed. When driving in conditions like traffic or a mountain road where a low speed has to be maintained, Active Steering increases the steering angle size. The front wheels show immediate response to small movements when the steering wheel is turned and enable the driver to maneuver through tight spaces.
Power Steering Rack
Two other types of power steering that are often found in BMWs are rack-and-pinion and recirculating ball. The rack-and-pinion system is found in many BMW models. This system needs two components to work including the BMW rack-and-pinion steering rack as well as a BMW power steering pump. The rack-and-pinion is a piece of metal tubing, situated perpendicular behind the wheels of the car. Inside the tube, you will find a flat piece of metal that has been altered to include teeth on its top.
In the center of the BMW rack-and-pinion, you will find a round seal that closes off either side of the rack, one at a time. Two-high pressure hoses that come from the steering mechanism, connect to both sides of the center seal. In one pressure hose, high-pressure hydraulic fuel is directed from the BMW Steering Pump to the steering mechanism while the other hose allows fluid to flow back to the pump. When the steering wheel turns left, the steering mechanism allows hydraulic fluid to pass to the left side of the track. It applies when turning right.
If you feel that your BMW power steering is not living up to the brand’s legendary performance, with signs such as needing more effort to turn the car, leaky steering fluid, or a steering wheel that vibrates tremendously when car is in idle, it is likely time for a new BMW steering pump. But, not to fret. We steer clear of the cheap replacements and provide you with only the highest quality to suite your BMW.
