Tesla LDU bearing kit

We ordered this kit due to having a very loud growl in a 14 model S LDU. After installing the kit the LDU was completely quite again. This is a well put together kit and we will definitely reuse this company's kit in the future. Only have 1 recommendation and that would be to include an instruction manual mostly for the drain kit. I was able to talk with someone and they walked me thought it and sent me pictures. Great customer service, they answered the phone even during them moving their shop location. I would give more then 5 starts if I could. Thank you
