For DIY-instructions you can search for the "ECGS Bushing" or "Needlebearing replace" videos.
Because with the bushing installation it is recommended to replace this seal as well. It should be the same work steps, except not to replace the bearing but only the seal.
for example:

(removal of the axle before the seal time mark)
or further tips from the tacomas which should not be much different:

I'm not a car mechanic either, but i'm confident that i can replace the bearing and seal. I've already ordered the ECGS bushing AND a new seal, as a precaution because the axle on my 2019 TRD Offroad already has play.
