Using these K - Tuned compliance bushings is straightforward. First, you need to remove the old, worn bushings from your car's suspension. Then, carefully install the new bushings in their place. Make sure to follow the proper alignment and torque specifications. When installing, it's a good idea to use a bit of lubricant to ease the process. As for maintenance, check the bushings regularly for signs of wear or damage. If you notice any cracking or excessive looseness, it might be time to replace them. Keep the bushings clean to prevent dirt and debris from causing premature wear. Also, avoid harsh chemicals when cleaning your car's undercarriage as they could damage the bushings.
