Using your K - Tuned Inner Tie Rod is easy. First, make sure your car is on a flat and stable surface. To adjust the tie rod, simply turn the center bar. You can thread it in or out on both sides at the same time to get the right alignment. When lowering your car, this two - point adjustment feature will help you align it properly. As for the bushings, if you choose rubber bushings, they'll last longer than OEM ones and give you better handling. Spherical bushings are great for race cars. When installing or replacing the tie rod or bushings, always wear safety gloves. After installation, take your car for a short test drive to check the handling. For maintenance, regularly check the tie rod for any signs of wear or damage. Clean the tie rod and bushings occasionally to keep them in good condition. If you notice any unusual noises or handling issues, have the tie rod inspected right away.
