Hello

If you're confident that none of the pullies are wobbling on their bearings the next step is to use a straight edge across the front of all the pullies to ensure all of them are running in -line and are square and true

also check the condition of the main crank pulley looking at all the pulley grooves for sings of bent ribs or stones stuck in the ribs

If this all looks OK then I'd next use a dial test indicator ( DTI) to measure the run -out on the crank pulley
