The differential had to be replaced on my 2015 RRS SVR. I recognize it is almost 8 years old but it only has 78k kilometres on it. Cost was $6000. There were no recalls for the differential and no surprise Land Rover would not cover any of the cost because of the number of years out of warranty. Dealer said a differential replacement is unusual especially with such low mileage. This is what happens as I impatiently wait for the 2024 SVR to be launched.
