Repair advice for Craftsman miter saw??

I’ve been given a Craftsman 10-inch compound miter saw model # 315.243130. When I got it I could not turn the table, so I took it apart and found a bit of shim wedged between the table edge and the frame. After reassembly I hear a grinding sound when I turn the table. The edge of the table rubs against the frame’s track that is right below it. I’ve checked the parts diagram in the manual, and don’t see any parts missing in that area of the saw.

option 1) grind down the edge of the table—don’t like that because both that edge and the track it’s rubbing on are milled to a shiny finish

option 2) put a washer on the pivot shaft to raise the table a tad—don’t like that because it will raise the table above the side supports of the frame, and I can’t see how that is good.

option 3) get used to the grinding noise—is this the best one? Maybe put some grease in that area to help catch dust.

I’m guessing that the table top should be as close as possible to level with the side supports for the workpiece; maybe a hair low, but not even a hair high.

comments and advice gratefully received I’ve never had a miter saw before, but you already know that by now.
