Some Lexus LS400 owners report experiencing clunking noises in the rear suspension, which can be attributed to completely worn out bushings in the carrier arms. These worn components can lead to looseness and excessive play, resulting in noticeable clunks when driving over bumps. Owners are advised to address this issue promptly, as worn bushings are crucial for maintaining the stability and alignment of the rear suspension system. Neglecting to replace them can lead to further damage to other suspension components and compromise the vehicle's overall handling and safety. To resolve the clunking noise, it is recommended that owners have a professional inspect the suspension system and replace any worn bushings as needed.
