Lexus LS400 passenger side rear air suspension not working, considering conversion kit or new suspension on Lexus LS400

Some 1991 Lexus LS400 owners report experiencing issues with the failing air ride system, particularly with the passenger side rear air suspension not functioning properly. These owners often face the dilemma of choosing between a conversion kit and new suspension components. Some owners find that opting for a conversion kit with a lifetime warranty can be a financially sound decision, offering a long-term solution that may save money compared to repeatedly replacing air ride components. Conversely, those who choose to purchase new suspension components may encounter ongoing maintenance costs and potential future issues with the air suspension system. Owners considering new components are advised to factor in the costs of maintenance and repairs against the upfront investment, as well as the reliability of sticking with the original air suspension. Ultimately, many owners emphasize the importance of evaluating the pros and cons of each option to make an informed decision that aligns with their needs and budget.
