To install the K - Tuned Lower Ball Joint, first, make sure your car is on a stable and level surface. Jack up the car safely and remove the old ball joint carefully. Then, fit the new ball joint into place, making sure it's properly aligned. During use, be aware that these ball joints won't work with our roll center adjusters. For maintenance, check the ball joints regularly for any signs of wear or damage. If you notice any unusual noises or handling issues, it's a good idea to inspect them right away. Keep them clean to prevent dirt and debris from affecting their performance.
