The steering shaft keeps the steering gearbox and steering wheel connected. The universal joint or also called as u-joint at the end of the steering shaft connects to the steering gearbox which has another u-joint that connects to the steering wheel allows for the angles between them to be supported resulting to your vehicle wheels smooth and easy turning. The intermediate steering shaft is an important component of your vehicle. It is considered unsafe to drive with a bad steering shaft on your vehicle and may put other people's lives with you at risk as well. If you are experiencing strange sounds, loose steering wheel tilt, difficulty in turning or your steering wheel does not go back to the center after turning then you may have a problem with your intermediate steering shaft. The intermediate steering shaft can easily be located inside the engine bay connected to the steering column which is on the driver side of the vehicle.
