3L V6 - replaced the front oil seal, timing belt - Belt noise

3L V6 - replaced the front oil seal, timing belt etc. After re-assemble per the Haynes repair, I continue to have what sounds like timing belt rubbing on pulleys or covers. disassembled to check correct timing, tentioner setting and deflection on the belt. Still have belt noise when test run. Checked with a straight edge along the front faces of the belt spockets to make sure tensioner is running true with the cam & crank sprockets. Have test run without timing belt cover & dampener to try & isolate were the belt noise is coming from. Any ideas or tips would be appreciated. Are there part(s) that should be replaced when doing this service? IE: tensioner bearing.
