I am looking for a word that doesn't sound as precise or intentional as 'adjusted', but doesn't have the accusative connotations as 'tampered'.
Example sentence:
The mechanic installed new struts on the car, but now the steering is out of alignment. I can't imagine why they would tamper with/adjust the steering.
I think 'adjust' in this sentence is wrong because it implies intentionally making something more exact, eg: 'I adjusted the temperature setting to make the room more comfortable'.
I think 'tamper' implies purposely, and perhaps nefariously, making something worse or dangerous, eg: 'The police found that the ATM had been tampered with'.
Is there a word in between these two?
