"It's unfortunate that Toyota made this so confusing but hopefully the confusion is behind us. Here's a parts list for anybody doing this job:
(qty:2) 90364-30011 Bearing, Needle (goes into inner bushing bore)
(qty:2) 90381-32001 Bushing, Inner (acts more like a bearing retainer now)
(qty:2) 90381-30003 Bushing, Outer (still the same as original)"

I have ordered the above parts, along with some new snap rings - doing both sides. I'm pretty sure this is the issue - my axles are slopping around in the knuckle... BAD bushings, soon to be replaced with new bearings. Getting closer to a road-worthy van....
