I just got home from a 3 hour drive with a terrible low pitch howling sound and high pitch vibration coming thru floor. Tiny bit of vibration came thru steering. Sound only happened above 60 mph. It goes away when I turn steering or touch brakes. I was driving my 2014 jeep srt. I'm thinking C V joint or wheel bearing. I immediately put jeep on hoist, nothing was hot, no abnormal play or tightness. Vehicle only has 12000 miles on it. Just wondering if anyone has had similar sounds and what it was? Could brembo brakes do anything weird? They don't seem tight and were not excesively hot, though they do drag a bit.
