I'm going to replace my front wheel bearings during my front brake job. Not sure if the bearings are shot, but it's better to have the parts and replace them vs having the van on a lift until the bearings are found.
I ordered genuine Toyota parts, but these same parts can be found for much, much less $$. Posting to save time & expense for my Van friends!

--Front 2WD outer bearing. Toyota part # 90368-19037 $25-30 each
actual part in box: NSK LM11949 & LM11910 easily found for about $10 each.

--Front 2WD inner bearing. Toyota part # 90368-31067 $25-30 each
actual part in box: Nachi LM67048 & LM67010 easily found for about $10 each.
