Your vehicle's steering system provides support for the weight of your vehicle, allows your foremost wheels to pivot while steering, and so much more. It also undergoes quite a beating while you're driving your vehicle, particularly from street pockets, hard impacts, and excessive road debris.

Your INFINITI's Steering Knuckle (Left), which is typically located behind your vehicle's front wheels, is essential to the overall function of your steering system. It provides an attachment point for other steering parts throughout your car such as the wheel bearings and struts.

To support each of these parts, your Steering Knuckle (Left) is created with sturdy steel material, making damaging or breaking it very challenging. However, an INFINITI's Steering Knuckle (Left) can stop functioning properly as a result of rusting, suspension impairment, aggressive driving and braking, and hard impacts from wrecks, potholes, and speed-bumps.

A damaged Steering Knuckle (Left) often impacts your steering. You might also notice vibrations in your steering wheel while on the road and various alignment problems. Much like an impaired grocery basket, your steering may pull to one side involuntarily while you’re on the road. Some other signs of an old Steering Knuckle (Left) include uneven tire wear and odd noises emanating from your car tires.

If your vehicle's Steering Knuckle (Left) has stopped working correctly, you should have it replaced as soon as possible by booking an appointment at an accredited INFINITI service center. It's not impossible to fix a damaged Steering Knuckle (Left) at home. But you run the risk of physical injury since doing so involves elevating your INFINITI and removing vital parts that, if not reinstalled the right way, could put you, your passengers, and other motorists at risk while driving.
