Rear sheep horn rubber sleeve

A Rear Sheep Horn Rubber Sleeve is a protective dust boot or cover designed for a specific suspension or drivetrain component in Tesla vehicles, often colloquially referred to as a "sheep horn" due to its shape. This sleeve is typically a flexible, durable rubber or polyurethane cover that shields a ball joint or linkage from dirt, moisture, and debris. Its primary function is to retain grease and prevent contamination, ensuring smooth operation and longevity of the joint it protects. Commonly found in multi-link rear suspensions, a torn or damaged sleeve can lead to premature wear, corrosion, and failure of the joint, resulting in noise, poor handling, or alignment issues.
