Steering Rack Chevrolet Traverse 3.6L 2009-2017 Location and Replacement

In this video, I show you the exact location and the complete step-by-step process to replace the power steering rack and pinion assembly on a 2009-2017 Chevrolet Traverse equipped with the 3.6L V6 engine.

The steering rack is responsible for converting your steering wheel’s rotation into the side-to-side movement of your front wheels. On this large Lambda-platform SUV, the steering rack is mounted low down at the back of the front subframe (cradle), positioned right behind the engine and transmission assembly. Because of the extremely tight clearances, this is a labor-intensive job that requires unbolting the rear subframe mounts, lowering the cradle slightly, and working around the exhaust and intermediate steering shaft. Knowing how to safely support the subframe, disconnect the hydraulic lines without stripping the fittings, and snake the rack out will save you hours of frustration.

Common Symptoms of a Failing Power Steering Rack:

• Severe power steering fluid leaks pooling under the center-rear area of the engine bay, often dripping from the torn rubber accordion boots
• A loud, persistent whining, groling, or squealing noise when turning the steering wheel, caused by air entering the hydraulic system
• “Stiff spots” or a sudden, complete loss of power steering assist, especially when turning at low speeds or when the vehicle is cold
• Excessive play or a loose feeling in the steering wheel, accompanied by a clunking or popping noise when driving over bumps or turning the wheel back and forth
• The vehicle constantly wanders or pulls to one side on the highway, making it difficult to keep the SUV traveling in a straight line

Safety First

Always prioritize safety before tackling a major suspension and steering overhaul. You will be working directly beneath a heavy vehicle and partially lowering the structural front subframe, meaning absolute stability is mandatory. Make sure the vehicle is parked on a flat, level surface, the emergency brake is securely engaged, and the front of the vehicle is safely supported on heavy-duty jack stands placed under stable frame points—never rely on a hydraulic floor jack alone. Chock the rear wheels securely.

Before disconnecting the intermediate steering shaft from inside the cabin or under the hood, you must lock the steering wheel securely in the straight-ahead position using a steering wheel holder or the seatbelt. If the steering wheel spins freely while the rack is disconnected, it will instantly snap the internal clockspring wire behind the airbag, destroying your horn, steering wheel controls, and SRS safety system. Protect your eyes from falling road grime and your skin from hydraulic fluid by wearing safety glasses and durable work gloves.
