Lexus LS460 front control arm replacement issue on Lexus LS460

Some Lexus LS460 owners report experiencing frequent control arm failure and knocking noises, which are common issues that can affect vehicle performance. Additionally, some owners have noted popping noises when braking at slow speeds, leading to diagnoses of bad control arms that require replacement. The cost of control arm replacements can be quite high, with dealer quotes ranging from $5,000 to over $9,200. For those considering a DIY approach, owners highlight the need to assess their skill level, tolerance for downtime, and the importance of ensuring proper torque settings and locking pin replacements. While control arm issues seem more prevalent in earlier model years, it remains uncertain if Lexus has fully resolved these problems in later models. Some owners choose to replace only the problematic control arms, such as the front lower arm, particularly when dealing with custom air suspension setups. These insights underscore the significance of promptly addressing control arm issues to maintain the Lexus LS460's performance and safety.
