Well all the seals and everything internal except the ring and pinion are wasted. again its rear 411. after submitting the parts list to brp they said were just going to send you a whole new rear end. number 506 on the way. i sure hope this one is quieter. Now i have u joints amongst other things that are now bad in which my opinion are caused from the rear end but no one will claim it. so after talking with customer service they said pretty much KMA. great. so 1600 and some change for parts and labor and im on the hook for 500 and some change. I didnt want to get to nasty but i did assure them after being a 14 year buyer of honda products and never an issue this would be my first and last BRP product. 1300 miles. how shitty can you be. We will be saving our receipts because i believe theres a driveline or the rear end causing this stuff to go bad premature. All we can hope to see down the road is a class action. They know theres a problem with these rear ends thats why there fixing them all but wont claim it. so i will fix my u joints and all wearable items associated with the rear end and walk away smiling.
