Infiniti FX 2009–2013 – common steering rack problems and polyurethane solutions from PolyPro
The Infiniti FX 2009–2013 is a mid-size premium crossover known for its dynamic road behavior, powerful engines, and distinctive sporty design. This model is highly valued by drivers for its combination of reliability and a well-engineered safety system.
At the same time, components responsible for steering precision, particularly the steering rack and its mounting elements, are subject to significant loads during active operation. This is especially true for the bushings, which are constantly affected by uneven road surfaces, high lateral forces, and the vehicle’s weight. As a result, these components often wear out faster than originally intended by the manufacturer.
Ignoring wear leads to vibrations, abnormal noises, front-end instability, and reduced steering accuracy. In advanced cases, it can cause additional damage to other steering components, making vehicle operation less comfortable and potentially unsafe.
What is a steering rack bushing and its function?
A steering rack bushing is a component of the suspension or steering system consisting of a metal sleeve and an elastic material such as polyurethane. It acts as a damper by absorbing vibrations, compensating for impacts, and helping maintain the correct position of the steering rack, which controls wheel direction. Thanks to this element, the steering system operates more smoothly, and the vehicle responds to steering inputs in a stable and predictable manner even on uneven roads.
The steering rack bushing performs several key functions:
- eliminates play and ensures precise operation of the steering mechanism;
- reduces vibrations transmitted to the steering wheel, improving driving comfort;
- holds the steering rack in the correct position, preventing displacement and premature wear;
- reduces impact loads on other suspension and steering components.
Typical problems and signs of wear
Unserviced bushings can become a safety risk, as instability in the steering mechanism directly affects vehicle control and handling precision. Timely replacement or reconstruction restores steering stability, ensures safe operation, and extends the service life of all steering system components, reducing the risk of failures and accidents.

- steering wheel play;
- delayed or vague steering response;
- knocking or abnormal noises during maneuvers or driving over rough roads;
- increased vibrations felt through the steering wheel;
- accelerated wear of adjacent components.
Ignoring these symptoms leads to serious consequences, including reduced handling precision, steering rack damage, premature wear of suspension components, increased accident risk, and higher repair costs.
PolyPro components for Infiniti FX
PolyPro steering rack bushings are manufactured from three-component hot-cured polyurethane of French origin. This material combines optimal stiffness comparable to original rubber components with high resistance to wear, temperature fluctuations, oils, chemicals, and environmental factors.
The use of polyurethane ensures durability, stable steering rack operation, and more precise vehicle control while reducing vibrations and impact loads. Unlike rubber alternatives, polyurethane does not stretch, crack, or lose elasticity even under intensive use, significantly extending the service life of the steering mechanism.
Installing PolyPro polyurethane bushings improves steering system performance, making vehicle responses more stable, accurate, and predictable even under high loads and challenging road conditions. PolyPro products directly contribute to driving safety and comfort.
Most of our components are covered by a 1-year warranty with no mileage limitation, confirmed by a warranty certificate. The warranty applies to the polyurethane material itself: it will not sag, tear, or delaminate, ensuring long-term reliable operation of the steering system.
