Are the front wheel bearing replacement prices I'm getting reasonable? on 2006 Toyota Sienna

We've been told we need to have our front-right wheel bearing replaced. The noise I am hearing is consistent with this. RepairPal is telling me the cost should run between $244 - $325. The quotes I've gotten have been for $415 and $455. What would be valid reasons for this difference?

Is your Sienna 2WD or AWD? Did the bearing fail possibly due to hitting a pothole 20K miles ago? ---they may be including alignment in their est. ------Get specifics on what is being done , and related warranty coverage for those items. But , yeah $20.00 is about right.
Sounds reasonably high...their valid reasons may markup...padded labor time...very busy schedule...possibly misunderstood and quoted you for BOTH wheel bearings.
