Hey Savesme$
What you've circled on your picture is just a fan that cools down the inducer motor behind it. It is positioned suprisingly close to the gas piping. Does any part of the inducer assy make contact with that piping?

Did this fan wobble before you adjusted it?

Noice from this inducer may indicate bearing problems that will require its replacement but this particular furnace inducer can also get noicy when anyone of the 3 main mounting screws that hold the whole assy loosen. This assembly is rubber dampened
Since you've had a 33 code it maybe an inducer failing but you can try seeing if any one of them feels a bit loose and is allowing the inducer assy to vibrate against the the furnace srructure. Either make small tightening adjustments and test or you can do it while the inducer is running. Often just pressing on the inducer body beside each mounting screw while the inducer is running will quieten it down and show you which one to tighten.
Tighten it too much and strip the thread where the mounting screws hold it or reposition it so the inside turbine binds against the inside casing and you are in for $$$.
