Detailed Description

On Tesla Model X SUVs, the front upper left control arm can crack and separate from the steering knuckle, creating a sudden steering concern. The original plastic cap design can also trap moisture around the ball joint, which contributes to creaking noises and accelerated wear. Dorman 527-511 addresses both issues with a stronger steel-based construction and a sealed joint design. This part cross-references Mevotech Supreme CMS95136 for the same application.
