Parts for your 2017 Lexus Is-Ball joints

Understanding Ball Joints on the 2017 Lexus IS

For those who own a 2017 Lexus IS or are simply curious about its suspension system, it's important to know about the role of ball joints. Ball joints are a crucial part of many modern vehicles' suspension and steering systems, and the 2017 Lexus IS is no exception. These small but mighty components help maintain the smooth and safe operation of the car, so understanding their purpose and when to replace or maintain them is key for keeping this luxury sedan in top shape.

So, what exactly are ball joints? They are spherical bearings that connect the control arms to the steering knuckles. This connection allows the wheels to move up and down with the suspension while also enabling them to turn left and right for steering. Think of ball joints like a smooth hinge that combines flexibility and strength, allowing the suspension to absorb bumps in the road and the steering to happen without a hitch.

On a 2017 Lexus IS, ball joints are fitted in the front suspension setup. The IS uses a double wishbone or multi-link suspension design in the front, depending on the specific model and trim, which commonly includes upper and lower control arms connected by ball joints. These components bear the weight of the vehicle and provide the necessary pivot points for steering control and suspension articulation. Without properly functioning ball joints, the handling of the car can feel loose or overly stiff, and there could be uneven tyre wear or even dangerous steering issues.

When it comes to maintenance, ball joints don't usually require constant attention but should be checked regularly during servicing or any suspension inspection. Over time, ball joints can wear out due to heat, dirt ingress, water, and general mechanical stress. When the protective rubber boots that cover the joints get damaged or cracked, grease can escape, and contaminants can get in, leading to a quicker deterioration of the joint.

Signs that ball joints might need replacement on the Lexus IS can include unusual noises like clunking or knocking, especially when turning or going over bumps. The steering might feel a bit loose, or there could be noticeable vibrations from the front end. Uneven or rapid tyre wear is another red flag since worn ball joints affect wheel alignment and camber angles.

Replacing ball joints isn't typically a DIY job for most car owners because it requires specialized tools and knowledge to safely remove and install the new joints without damaging the suspension components. It's best carried out by a professional mechanic who can also perform a wheel alignment afterward to ensure optimal handling and tyre life.

Regular check-ups as part of your 2017 Lexus IS servicing schedule will help spot any wear before it becomes a safety issue. For those driving in harsh conditions like off-road, rough or unsealed roads, or areas with a lot of moisture, ball joints can take a bigger beating and might need closer attention. Maintaining proper lubrication and replacing worn boots promptly can prolong the life of these parts.

Overall, ball joints form an essential link in the suspension and steering system of the 2017 Lexus IS. They play a vital role in the vehicle's smooth ride quality, precise steering response, and safety. Although they are designed to last many kilometres, wear and tear are inevitable, and keeping an eye on their condition is part of good vehicle care. Whether you're cruising on city streets or hitting the open road, healthy ball joints help ensure your Lexus IS remains a pleasure to drive.
