Levante 2017 — why does the rear knuckle suffer because of a single bushing?
Maserati Levante is the embodiment of Italian style — a premium SUV that combines luxury-class comfort with sporty dynamics. Its suspension is designed for high speeds and comfort, but even such a complex and reliable system has its own Achilles’ heel.
Sometimes owners begin to notice alarming symptoms: squeaks, knocks from the rear, slight play, or a feeling of instability during sharp maneuvers. Many assume this indicates a serious failure, but in most cases the culprit is just one single rear knuckle bushing.
This small component is critically important for stability and safety. Over time, it loses elasticity and no longer holds the knuckle in the optimal position, which leads to additional stress on neighboring components and premature wear of the entire suspension. The paradox is that a relatively inexpensive element can damage a costly and technologically advanced assembly.


What is this part and why is it so important?
Simply put, the rear knuckle (or steering knuckle) is the foundation of the rear suspension. The wheel, braking system, and all major control arms are attached to it. In the Maserati Levante, this component ensures that the wheels remain at the correct angle, allowing the vehicle to respond precisely even at high speeds.
The bushing in this system acts like a joint. It allows the suspension to move smoothly while absorbing road impacts. When this joint wears out, the knuckle loses rigid fixation. It resembles a dislocation: the wheel begins to behave unpredictably, wheel alignment is disturbed, and premium tires can wear out in just a few weeks.
That is why the condition of one small bushing is the key to ensuring the entire rear axle of your Maserati works like a Swiss watch.

Why can one part damage the rear knuckle?
Although the rear knuckle itself is a strong component, a worn or weak bushing can create excessive loads:
• increased play is transferred to the shaft journal;
• metal components begin to rub against each other, causing squeaks and knocks;
• incorrect positioning leads to uneven load on tires and suspension;
• prolonged driving with a worn suspension bushing accelerates wear of bearings, bolts, and other knuckle components.
Thus, even a single low-quality or worn bushing can significantly affect vehicle behavior and driver safety.
Symptoms of a worn bushing
When a Maserati Levante begins to lose its refined handling, it signals the owner through a series of characteristic symptoms. The first signs are usually unusual noises — squeaks and dull knocks that are uncharacteristic of a premium vehicle, even on minor road imperfections.
Over time, you may feel looseness in the rear of the car, as if it slightly sways or sinks during maneuvers. Uneven tire wear on the rear axle and less precise steering response are clear indicators that the bushing is no longer maintaining correct knuckle geometry.
Even slight vibrations during acceleration or braking indicate that the component is no longer absorbing loads effectively. Timely inspection allows you to stop suspension degradation early and protect the expensive knuckle from damage.



**PolyPro** bushing
That is where the solution from **PolyPro** comes in. Our polyurethane rear knuckle bushing **pp2831c – 670037242; 670037240** for the Maserati Levante 2017 is not just a replacement — it is an upgrade.
We combined high strength with durability. The material is resistant to abrasion, dirt, moisture, and extreme temperature changes. Unlike rubber, polyurethane does not deform over time and does not harden in cold weather. It constantly keeps the knuckle in the correct position, ensuring stable and predictable suspension operation.
Installing a polyurethane bushing allows you to:
• restore precise rear knuckle positioning;
• reduce play, knocks, and squeaks;
• improve handling and stability, especially in corners;
• extend the service life of bearings and suspension components.
Advantages of the **PolyPro** polyurethane bushing
When you choose polyurethane from **PolyPro**, you benefit from our 10 years of experience and confidence in every kilometer. This component is designed for drivers who do not spare their Maserati Levante — it withstands aggressive driving and poor road conditions.
The bushing works as a professional damper, effectively absorbing vibrations and reducing noise, while fitting perfectly into factory mounting points. It is a smart investment that helps avoid costly replacement of the knuckle or shock absorbers.
Key advantages:
• High durability;
• Stable and predictable suspension behavior;
• Increased comfort and reduced noise;
• Easy installation;
• Cost efficiency.
In summary, even such a small component as a rear knuckle bushing has a critical impact on vehicle behavior. Timely replacement with high-quality polyurethane improves safety, comfort, and stability while minimizing unexpected repair costs.
