Hell, I even had to replace the transmission fluid on my 120 after the last trip!Which is what most people do and which is why I am in business!
In all seriousness, Toyota considers wheel bearings "life of vehicle" parts if maintained according to maintenance standards:
On the old solid axle trucks:
Bearing repack: every 30k miles or after significant water crossings.
Front axle rebuild every 60k miles.
Grease in knuckle through inspection hole every 15k miles.
For IFS trucks, Toyota mandates a bearing repack every 30k miles and CV inspection at every oil change interval.
