Those who tell you they clean the stator with alcohol have no idea what they are doing. Our process does not use alcohol, which is only a temporary fix as it does not remove the crystallized coolant from deep within the stator coils - it just dries them out, plus it can damage the thin insulation layer on the stator windings. Those crystals will re-absorb moisture, which will leave you back where you started with a failed LDU. We REMOVE the dried coolant, thoroughly check the rest of the LDU for other issues, then install new rotor bearings and seals. Once all done, we install a weep hole to prevent future build up of coolant.
Also, we do not believe in the coolant delete, which removes cooling from the rotor. We have seen MELTED rotors from "deleted" LDU's. But you say 'Tesla deletes them' - Yes, and they also reprogram the LDU with stricter thermal limits - reducing overall power output and regeneration. Those who do aftermarket deletes cannot reprogram them. Thus you have a car that thinks it's rotor is being cooled when it is not - a recipe for disaster.
The truth is, the seal in question typically does not suddenly fail - it leaks ONE drop every 20-50 miles from new. This is not a failure but normal for such a seal. The issue is the leaked coolant has no place to go, and at some point your LDU drowns. What about those droplets on the sensor? Since this seal leaks from day one, this is a convenient sales tactic as a brand new motor with 1k miles will have drops on the sensor. This is where our weep hole comes into play. We have numerous LDU's going strong well over the 200k mile mark and countless over 100k miles. LDU Rebuild #1, which in our own Model S, as of this writing, has over 270k miles post rebuild and still going strong - and we tow heavily with this car.
Thus, reach out to us using the contact form on the left. We can discuss what you car needs. We also offer rebuild services for shops too!
