Restore your Tesla’s performance and reliability with Tesla Drive Unit and Large Drive Unit (LDU) rebuilds. We replace or rebuild Tesla drive units for Model S, Model 3, Model X, & Model Y, delivering performance that surpasses factory remanufactured units. Drivers across Santa Clara, San Jose and Fremont rely on us to get back on the road faster, with smoother acceleration and quieter drive units,
Is your Tesla suffering from internal coolant intrusion in the drive unit?
Tesla’s original Large Drive Unit (LDU) design routes liquid coolant through the rotor to manage heat, a clever idea in theory but a known weak point in practice. Over time, the rotor coolant seal can wear out, allowing coolant to leak into the motor.
For just $100, we manually inspect your Tesla’s drive unit for coolant leaks, giving you a clear assessment to make an informed repair decision.
Once compromised, coolant seeps into areas it should never reach causing:
It can strip bearing lubricant and corrode component
Lead to whining or grinding noises
Degrade stator insulation
Damage Inverter
Flash Drive System Error Codes
Does Your Tesla Have One of These Symptoms?
These warning signs may indicate internal coolant contamination in the drive unit, which can lead to early drive unit failure if left untreated:
Dashboard alerts related to propulsion or voltage issues
Damaged stator windings or internal shorts can cause unstable power delivery, making driving unpredictable.
Sudden power loss or hesitation during acceleration
Often an early indicator that coolant is leaking inside the drive unit, not externally. This can compromise the motor and reduce drivability.
Dashboard alerts related to propulsion or voltage issues
Damaged stator windings or internal shorts can cause unstable power delivery, making driving unpredictable.
High-pitched whining or “toy car” sounds during acceleration
Commonly caused by bearing wear or inverter faults inside the drive unit. Error codes may also appear, signaling internal drive unit problems.
Tesla Drive Unit Services
Tesla Model S
LDU Maintenance
$1,900 / 3,900
We can either prevent the coolant leak by blocking the coolant flow from the rotor only for $1900, following Tesla’s new design if your car is drivable. It requires dropping your subframe to properly access to flawed design area
Gearbox rebuild eliminates gearbox noise for $3900. This is also a preventative measure if the car is drivable, replacing worn bearings and all seals.
A $95 inspection is highly recommended to identify if coolant has already leaked, visually inspecting the encoder (speed sensor) and measuring the electric motor.
Tesla Model S
Full Drive Unit Rebuild
$4,900 Special
Our most popular option, this complete drive unit rebuild covers the mechanical components, stator, gearbox, and inverter.
We use OEM-quality parts, enhance electrical isolation, and perform a coolant delete to improve reliability beyond Tesla’s remanufactured standard.
WHY CHOOSE US FOR YOUR TESLA DRIVE UNIT REBUILD?
We offer multiple Tesla drive unit service options at a fraction of dealership pricing, with our most popular choice being a complete drive unit rebuild. Unlike shops that only replace gearbox bearings, we fully refurbish the entire drive unit, including the mechanical components, stator, gearbox, and inverter.
Our in-house refurbishment process uses OEM-quality parts from Tesla suppliers, while enhancing electrical isolation within the motor and performing a coolant delete exactly to Tesla’s specifications, improving performance and reliability beyond the factory standard.
We back our work with a warranty of up to 4 years, giving you confidence and peace of mind on the road.

What Customers Say About Us
Clarise Blanchard
“Hello, it is an absolute privilege to leave a review for this amazing auto shop! I’ve just spent close to an hour sharing information and possibilities with the owner of Prius and Tesla Auto, Adam, and he could not have been more insightful, creative, understanding and knowledgeable! And his prices are more than reasonable. It was absolutely beautiful to talk with someone who is knowledgeable, especially after our horrible experience at the dealership……. If you need support or help with a Prius or Tesla, please make sure you have a conversation with this auto shop. Thank you so very much, Adam, and you can be assured we will meet again. Chuck Blanchard!“
