Whether you’re commuting from Katy on I-10, navigating the busy streets of the Houston Galleria, or heading home to Sugar Land, your Tesla’s drive unit is the silent powerhouse that makes your drive possible. However, the extreme Texas heat and high-mileage commutes can take a toll on these complex assemblies. We specialize in diagnosing and repairing the most notorious Tesla drive unit issues—from the “milling machine” sound of worn rotor bearings to the critical Large Drive Unit (LDU) internal coolant leaks that can lead to catastrophic isolation faults. While the dealership often suggests a full, high-cost unit replacement, our technicians provide a precision alternative. We focus on component-level repairs, including coolant delete retrofits and high-grade ceramic bearing replacements, ensuring your Model S, 3, X, or Y remains as quiet and efficient as the day you took delivery.

Specialized Tesla Drive Unit Services

Tesla drive units combine the motor, inverter, and gearbox into one system. We offer targeted solutions for each:

• LDU Coolant Manifold Upgrade: A permanent fix for the common internal rotor seal leak in older Model S and X units, preventing coolant from entering the motor windings.

• Precision Bearing Replacement: Swapping out worn factory bearings with high-performance SKF ceramic bearings to eliminate humming and high-pitched whining.

• Reduction Gear Oil Service: Much like a traditional differential, your Tesla gearbox needs fresh lubrication. We recommend a flush every 50,000–100,000 miles to prevent gear pitting.

• Inverter & Isolation Fault Diagnostics: Using advanced software to pinpoint “Reduced Power” alerts and BMS isolation codes (like BMS_w158) caused by moisture or internal shorts.
