Rear knuckle Tesla Model Y 2020: five silent blocks and engineering logic

Tesla Model Y 2020 is an innovative electric crossover that combines high efficiency of the electric drive, advanced technologies, and increased passenger safety. For stable operation and long service life of the vehicle, the rear knuckle plays an important role, as it relies on five key polyurethane silent blocks. These components determine suspension accuracy, wheel control, and overall driving stability.

A silent block is an elastic suspension element located between metal units and performing a damping function. It absorbs vibrations, reduces impacts, stabilizes the position of the knuckle and arms, and prevents premature wear of adjacent components. In Tesla Model Y 2020, engineers positioned five such elements to ensure optimal load on each unit and to maximize the system’s service life.

 

Signs of wear and causes

Elastic suspension bushings are subjected to constant mechanical loads from vehicle weight, acceleration, braking, and road irregularities. The main signs of wear include:

• the appearance of extraneous knocks and noises while driving;
• uneven or rapid tire wear;
• loss of steering precision and instability of the rear knuckle;
• vibrations and increased load on neighboring units and the body.

The causes of wear may vary: constant operating forces, exposure to road chemicals, temperature fluctuations, material aging, or impact damage.

Ignoring signs of wear can lead to rear knuckle instability, uneven tire wear, abnormal noises, and increased stress on the body and other components. Timely replacement or restoration of polyurethane silent blocks ensures safety, vehicle control, and driving comfort.
