BMW X5 Control Arms and Parts
The BMW X5 is a mid-size luxury performance SUV that debuted in the U.S. in 1999. One of the main contributing factors to its smoothness is the BMW X5 control arms and parts, which lie on the underbody of the vehicle.What parts are used in BMW X5 control arms?
The control arm system generally uses three parts. These three BMW X5 parts will come in specialized kits, but you may be able to get individual parts separately if necessary. Here are the three BMW X5 parts used in control arms and what they do for your car.
- Control arm: The BMW arm itself is a large metal bar that serves as a secure connection between the suspension and body of the BMW X5. This piece of metal keeps the BMW's systems in place while still allowing for movement.
- Ball joint: The ball joint is a ball-and-socket design that allows each of the BMW's wheels to move up and down independently. It does this by fitting a ball inside of a slightly larger socket, which is then kept in place by a plastic or rubber casing.
- Bushings: Of course, neither the arm nor the ball joint would remain on the underbody of the BMW X5 without proper affixing. The bushings perform this task for the BMW, keeping all of the parts securely in place. Usually, each BMW control arm uses three individual bushings: one at the ball joint end and two at the other side. These parts are essential for proper arm functioning.
Control arms have three important tasks for all cars, which are described below.
- Movement: In the control arms are specialized ball joints. These parts are able to move vertically, which means that each system is able to move vertically independently. Rather than passing over a pothole and feeling a jolt in the interior of the X5, the BMW's wheels will move to grip the road at a different level. This enhances stability and keeps jolts to a minimum inside the BMW's body.
- Vibration dampening: While vertical movement helps with dampening the amount of vibration from the road, another aspect of the BMW control arms parts dampens vibration more. Since the arms act as connections between the cushioning system, wheels, and body of the BMW X5, these parts are also able to pass much of the vibration to the BMW's suspension rather than to the body. Therefore, most vibration, except in extreme cases, will only be felt in the BMW's suspension.
- Alignment: The final function of the control arms and their associated parts in the BMW X5, is to keep the body and wheels of the car in line. The thick metal control arm holds all of the X5's parts in place at the correct angle when moving over extreme terrain.
