Hello, 2013 Toyota Prius.
I hit a huge pothole on the highway passenger side, started hearing a whirring wheel bearing sound immediately afterwards. Bad when turning left, almost gone when turning right.
I assumed it was my passenger side front. However there is no play in any of the 4 wheels, no unusual sounds from any of the 4 wheels while spinning them, only hear sounds from 45-65mph, not above or below that.
It SOUNDED like it was coming from the front of the vehicle however I couldn't confirm which side.
Then the weirdest thing happens this morning. Days after the incident/noise began, I get a code and several warning lights for Rear Speed sensor LH circuit. I'm assuming that's my rear drivers side hub. This is the exact opposite of where I impacted the pothole (passenger side).
I jacked up the car and my rear driver's side wheel has no play, and all I can hear is brake rotor when I turn it.
This is very strange to me and I don't want to replace parts for no reason, these hub assemblies are $400 from toyota each. What should I do?
Your right front wheel bearing is bad.

So you think the code about rear speed sensor LH is just a huge coincidence?
Not necessarily, a big enough impact could have affected it. Typically wheel sensor problems are caused by the wiring and connectors due to constant flexing and if the car rocked around after the big hit that could have done it.
