2006 X - T.O bearings replaced at 14k and again at 42k under warranty. They replaced the clutch and housing the second time around. Won't be too surprised if I have to do it again in another 10k. BTW - Toyota dealers do have a log of ALL of your services done in North America. I made the service guy print it out to show them that I've been to other dealers during separate occasions during the lifetime of this truck to get this problem checked out.
