<h2><span style="font-size: 18px;">What is a steering knuckle assembly?</span></h2><p style="text-align: justify;"><span style="font-size: 14px;">A steering knuckle assembly is a key component of a vehicle's steering and suspension system. It is essentially a connection point between the wheel and the suspension, allowing the wheel to turn left and right while also supporting the weight of the vehicle. The steering knuckle assembly is located at the front of the vehicle, and it contains several important parts including the hub, spindle, bearings, and steering arm. When the driver turns the steering wheel, the steering system uses various mechanical linkages and hydraulic components to transfer that motion to the steering knuckle assembly, causing the wheels to turn accordingly. The steering knuckle assembly also helps <a href="https://a-premium.com/shock-absorber">absorb shock</a> and vibration from the road, providing a smoother ride for the driver and passengers.</span><strong><img style="display: block; margin-left: auto; margin-right: auto;" src="https://media.cdn.a-premium.com/2022/item/image/93a12585e3ec4b46b9852abaf8a8d172.gif" alt="steering knuckle assembly diagram" width="1000" height="375" /></strong></p><h2><span style="font-size: 18px;">Common reasons for steering knuckle assembly failure</span></h2><p><span style="font-size: 14px;">Steering knuckle assemblies can fail due to a variety of factors, including excessive wear and tear over time, lack of proper lubrication leading to increased friction, impact damage from driving over road hazards, corrosion from environmental exposure, improper installation or maintenance, manufacturing defects, overloading the vehicle beyond its capacity, and suspension modifications that place additional stresses on the system.&nbsp;</span></p><h2><span style="font-size: 16px;">A-Premium steering knuckle: Steering you to a smoother drive</span></h2><p style="text-align: justify;"><span style="font-size: 14px;">Engineered to high standards, A-Premium's steering knuckle assemblies deliver uncompromising durability, responsiveness, and safety to elevate your driving experience.
