Why Tesla Owners Replace Upper Control Arms

Tesla vehicles deliver instant torque, which puts additional stress on suspension components. Over time, the upper control arm ball joint can wear, causing noise and alignment issues.

Replacing worn arms helps:

• Restore quiet ride

• Protect tires from uneven wear
• Maintain safe suspension performance
