Multiple bad hub assemblies

2011 Prius III with ~150k miles. I had to replace the passenger side rear hub assembly earlier this year because it went bad. Grinding noise when turning by hand, and LOUD cycling noise when driving. Loud enough to almost drown out the radio. Replaced it, everything was good. Then started hearing some very low "lub lub" noises when driving recently, and have been having a clicking noise coming from the driver side rear wheel. Removed the wheel and turned the hub, got a little grinding so I replaced that as well. The "lub lub" did not improve much when driving, so I checked the front wheels as well. I could not detect a problem turning the hubs with the wheels off, although it was a little stiffer on the driver side. But with the wheels on (so it takes less effort to turn them) I can hear a faint, but distinct grinding from the bearings when turning the front driver side. I think that one is bad as well.

I haven't had to replace any hub in previous cars, so I'm not sure if this is normal. The car does have 150-160k miles on it, mostly highway, and I have also been taking some long car trips this year (6, 8, 10, 14+hrs straight). Maybe I'm just straining the car, but though I'd ask just in case. Sometimes there are underlying problems that can cause parts to prematurely fail, so I do want to see if anyone has a differing opinion before I find myself replacing the hubs every few months.

I've never used "Dura Go", not sure if I've heard of them. I have used Duralast parts before, but I don't think I'd trust it in a critical part like this. I ordered Moogs for both the rear hub, and the front I'm going to be replacing. AutoZone accidentally sent me a Timken hub on my last order, which I think is just as good even though it has a shorter warranty.
