remove upstream oxygen sensor

What is your question?

On a 1997 Dodge Stratus, when I try to get access to the upstream oxygen sensor from above or below, there is very little room to move a ratchet or breaker bar. Are there parts that must be removed to get enough access to remove it.(Such as axle, etc??)?? Also, is there a way to make the sensor looser. It is really hard to try to turn.
