Prius Sounds Like It's Working Too Hard

this could be a wheel bearing

Thanks! I followed some tips on identifying wheel bearing issues - jacked car up, wiggled tire, etc. Couldn't perceive a clear indicator so I took it for diagnostics at a shop - they used a stethoscope and identified one totally shot front wheel bearing and the other front bearing about to die. Additionally, one of my three motor mounts had a crack, allowing for too much movement. Shop and Prius forums seen to indicate that the Prius has been know to have wheel bearing issues. Bonus fact, shop recommended that I not drive on highways (or at all, if I can help it) until fixing the bearings.

Thought so as this is typically the root cause of noise only when wheels are turning. This is an easy part to replace and relatively inexpensive. Both front hub assemblies run around $54.74 for the pair.... https://www.autoshack.com/Auto/Wheels-Tires-Parts/Wheel-Hubs-Bearings/HB613267PR?keywords=2007+Toyota+Prius&msclkid=82ec3976126d1592352864eb062ea452&utm_source=bing&utm_medium=cpc&utm_campaign=AutoShack%20-%20USA%20-%20Bing%20Shopping&utm_term=4576648434606044&utm_content=Ad%20group%20%231 and should take no more than 2 hours to remove and install. Just be sure to torque the bolts as recommended when installing.
