Infiniti QX4 Flex Coupling-Steering Damper Replacement at your home or office.

What is the Flex Coupling-Steering Damper all about?

When you are driving, vibrations that result from wheel contact with the road moves through the suspension, steering components, and eventually the steering column. The flex coupling incorporates a rubber disc that absorbs excess vibrations that make your vehicle hard to handle or cause driver fatigue. Without the flex coupling, the vibrations you would feel in the steering wheel would make your hands and arms tired and sore after just a short time interval. In addition to vibration dampening, the flex coupling enables the steering column to turn freely even when it isn’t completely straight. A universal joint is designed into the flex coupling that allows your steering column to rotate freely while being at an angle due to suspension travel. If the steering damper is damaged or worn, you will feel more road vibration in the steering wheel. If the flex coupling portion comes loose, your steering will be less responsive to small side-to-side movements and feel jerky.
