squeeky & grinding sound while turning

I tried replacing just bearing slides previously, but because I ignored the squeel too long, the drum wore through the bearing and new slides wouldn't stay in place, so I did this job twice. Open door, two Philips screws hold front edge of top to front panel (not clips to pry like somemodels). Lift top panel up to maneuver the tabs from control panel slots. Set top panel aside. Two more screws accessed from inside hold front panel top to side panels. Once they're out, lean front panel against something to keep wires from pulling. Pop bearing collar out with your fingers or a flat screw driver, top edge out first. Put new one in, replace tabs (4 of them) while your at it. Assemble in reverse order. Lesson learns...check those sacrificial slides after 8 years, spend te bucks to replace, and don't ignore the squeek sound or you'll have to replace the bearing as well.
