Dryers squeaks differently after repair

I recently replaced 2 drum support rollers, 2 front tumbler bearings, 2 dryer drum roller axles a belt and the belt tension pulley and the dryer due to a horribly locked up roller and screeching that was insane.

I put it all back together and now there’s a slight "tumble" sound as well as an intermittent squeaking.

Any ideas as to what I should attack next?

Thanks.
