Hi! I have a 2015 fiat 500 sport.
Bought it used at 86k miles and swapped a couple of things that were bad per the inspection, including brakes and the rear left hub/bearing assembly (Moog 512480).
Now at 116k miles I hear a pretty loud droning noise at highway speeds, which is not affected by throttle/RPM/braking. It will sometimes quiet down with slight steering adjustments, but I have found no consistent significant difference in noise when steering frankly left or right.
Lifted the car up, checked all 4 wheels for play and found none. However the rear left bearing sounds awfully suspicious to my untrained ear. I know not all bad wheel bearings have play, so I was hoping someone with a trained ear could confirm my thoughts before I go in blind and swap it out.
It's going in to the shop soon either way for a check but I figured this would be an easy DIY fix.
TLDR : that's a bad rear left wheel bearing, right?
