When it comes to vehicle maintenance, many drivers tend to focus on oil changes, brake inspections, and fluid levels. However, one of the most crucial aspects of maintaining your vehicle's performance and safety is often overlooked: tire rotations. This simple yet vital service can have a significant impact on the longevity of your tires and the overall performance of your vehicle. Understanding Tire Wear Tires experience different wear patterns based on various factors, including driving habits, the weight of the vehicle, and the road conditions. Typically, tires wear unevenly because the front tires are responsible for steering and bearing more weight during turns and stops. As a result, the front tires may wear down more quickly than the rear ones. Common Symptoms of Uneven Tire Wear Being aware of the signs that indicate your tires need rotation can save you from costly replacements and improve your driving experience. Here are some common ... read more

As the automotive industry rapidly evolves, one of the most significant advancements is the integration of Advanced Driver Assistance Systems (ADAS). These innovative technologies are transforming the way we drive, making vehicles safer and more efficient. By 2030, it’s projected that a staggering 90% of all vehicles sold worldwide will be equipped with some form of ADAS. This shift marks a significant change in how manufacturers approach vehicle safety, and it's reshaping the landscape of automotive repair and maintenance. What is ADAS? ADAS encompasses a wide range of technologies designed to enhance vehicle safety and facilitate easier driving. These systems include features like adaptive cruise control, lane departure warnings, automatic emergency braking, and parking assistance. Various automakers have developed their own terminologies for these systems; for instance, Honda refers to their suite of features as Intelligent Driver Assistance Systems (IDA ... read more

In the automotive repair world, the practice of turning rotors has long been a standard procedure. However, as vehicle technology advances, it’s becoming clear that this method is not only outdated but can also pose serious dangers to both drivers and their vehicles. At Hillside Auto Repair, where we specialize in brake services, we advocate for a modern approach that prioritizes safety, efficiency, and long-term cost-effectiveness. Understanding the Old Practice of Turning Rotors Turning rotors, or resurfacing, involves machining the rotor's surface to remove imperfections, such as grooves and warps, in order to restore smooth braking performance. This practice was once a common solution to prolonging rotor life, particularly when brake pads were replaced. Mechanics believed that resurfacing could extend the service life of rotors, allowing for better contact with the new pads. However, the reality is that this method has serious limitations and risks, es ... read more

When it comes to your vehicle's performance, many components work together harmoniously to ensure a smooth ride. One of the most crucial, yet often overlooked, parts is the universal joint, commonly known as the u-joint. In this blog post, we will delve into what a u-joint is, its components, how it functions within your vehicle, and the signs of a failing u-joint. What is a U-Joint? A universal joint is a flexible coupling that connects two rotating shafts, allowing for the transfer of torque and the accommodation of angular misalignment between the shafts. In vehicles, u-joints are primarily found in the driveshaft, which transmits power from the transmission to the rear axle (in rear-wheel-drive vehicles) or to the front wheels (in all-wheel-drive vehicles). Components of a U-Joint A typical u-joint consists of several key components: Cross: The central piece of the u-joint, usually made of steel, which has four trunnions protruding from i ... read more
