I could definitely be wrong but I don't think Sequoias have carrier bearings. I found that in some forum posts here (and on other sites) and immediately got excited about a relatively cheap bearing to replace. Surely that couldn't hurt anything, right? Turned out that I couldn't find a part number anywhere. Finally, I under the truck and look around. If memory serves, the drive shaft goes directly from the back of the transfer case to the rear axle, no carrier bearing. Now that I say that, maybe it is different for 4wd vs 2wd. I know that most of the references I found were for Tundras.
