I just put one in after a Lexus bearing failed...I think the hub wasn't pressed in correctly causing the failure. I see 3 grades from YB&H, I got the mid grade ($168) which was cheaper than the Lexus bearing alone (nonhub). Not longevity or mileage report but it's an NSK in mineAnyone here use the front bearing assmbly from Yota Bearings and Hubs? They are significantly cheaper than other though they aren't made with a Koyo bearing.
