Hi all, Long story short: for nearly 2 years we've had a low rumble developing in our 2012 RAV4 (Sport) and changing character over time from hard to hear to now very obvious (and grinding noise). Definite related to drive train as it changes speed with vehicle speed. It has become more pronounced through brake pad change and rotor resurfacing, tire change/balancing, and an alignment. I've asked the dealer to look for the source during regular service with nothing flagged. Finally paid...
