Narrative:
On about 3 different occasions an emb aircraft coming out of a check; the upper rudder bearing was changed without the rudder being removed. Bearing (in its housing) was replaced along with most of the hardware during these events. Manual calls for the rudder to be removed. The upper and lower bearing can be changed without rudder removed. The maintenance manual gives us the leeway to short a task. The bearing can be removed and replaced with no forcing or problems. After viewing the emb disposition about not removing the rudder for the upper and lower bearing but doing operations checks after. Have changed none since. Next time operations checks will be complied with.
