Learn more about our GM Genuine Steering System Components, including the testing process
Our GM Genuine Steering System Components offer the added peace of mind that comes with knowing the parts in your vehicle have been thoroughly tested and rigorously validated and are engineered with years of development.  No company or parts brand knows your GM vehicle better than the company that designed and manufactured it from the ground up. That is especially true when it comes to a crucial safety component such as a steering system.

Your vehicle’s steering components – including gears, the intermediate shaft, tie rods and the steering column – help establish the ride and handling of a vehicle, as well as directional control and steering assist for the driver.  Because of this, hundreds of tests are performed on the vehicle's electronic power steering systems before installation, examining areas like durability, performance, corrosion, fatigue and temperature cycle. 

How do we test our steering systems? 
Our steering systems undergo a number of tests.  Each individual part is repeatedly heated and cooled to extreme temperatures in order to test all critical electrical connections, while at the same time vibrating violently to expose potential weakness. During testing, the steering gear not only undergoes salt-spray testing in a lab but also at a full vehicle level using accelerated corrosion exposure with salt spray, extreme heat and extreme humidity in a test booth. 

It goes through real-world corrosion tests by being exposed to actual road salt and road salt splash elements for months at a time. In addition, the components endure impact loading to test their strength and verify performance during normal everyday driving as well as those more unexpected events, like driving through a pothole. 

GM Genuine steering systems also include complicated mechanical, electrical and software components. The steering gear in particular is running its own diagnostic checks more than 1,000 times per second to make sure it’s functioning properly, alongside the thousands of similar checks the vehicle itself is doing.
