2009 Patriot Rear Drum Brakes Help

Hey folks, I need a bit of advice from y'all. A couple months ago I took the Pat in to a local shop to have my brakes serviced. They replaced my rear drums and shoes. A few days later under light to medium braking I could hear a pulsating grind sound coming from the rear end.

I took it back to the shop and they could not find anything wrong with the drum system.

I finally got fed up with the noise and took the tires off myself yesterday to inspect. Aside from a good deal of brake dust, I did not see anything wrong. No shiny spots or anything. I said Fk it and went ahead and replaced the shoes and drums myself this time again.... Put it all back together and the pulsating grind sound is still there.... It does not grab anywhere when in the air and spinning by hand, but when you drive and give brake pedal pressure you can hear it clear as day..... I am at a total loss here..... I was thinking maybe new hardware kit, but it all looked fine....

Disc brakes pulse cause there warped. Look at the front for the hell of it. And it sounds like you rear drums might no be adjust right if they freely spin while the car is on jack stands. Should only get about a rotation to a rotation and a half when the drums are adjusted right.
