Here is how to fix the Noise Issue ,.you have two options:
option #1
Occasionally, an SM57 may develop an audible rattle when the microphone is shaken vigorously. The noise may be reduced or eliminated by inserting a small piece of acoustic foam (such as used in the 55SH Series II grill) between the SM57 grill housing and the black metal screen.
Use a bright light to locate one of the four flat areas beneath the screen. Carefully insert the foam piece between the grill frame and screen. Push it in until no longer visible. If necessary, repeat using one of the other flat areas.
The addition of this foam does not degrade the SM57 frequency response or polar pattern. Contact Shure Applications Engineering at 800-516-2525 or 847-600-8440 to obtain small squares of the acoustic foam.
Option #2
You will need a toothpick and Duco Cement (available from a hardware store). Locate the black metal screen that is 1.25" below the SM57 grill. This screen is right below the band that says "Shure" and "SM57". In a strong light, look carefully through the screen. You will see four bright areas that are just below the screen. Each of these areas is 90 degrees apart from the next area. These four areas are the glue targets.
Stand the microphone upside down on its grill. Put a small dab of cement (the size of a pin head) on the toothpick. Place the cement on the first area. Let the cement flow downward and get between the black screen and the rotating plastic grill. Repeat for the remaining three areas. Let the cement dry thoroughly, then break off the length of toothpick that is not required.
This technique should stop the rattling. Use the cement sparingly.
Never cover up this black screen with duct tape as this will destroy the SM57 directionality.

I have used medium CA glue to build 4 "bridges" from the grill to the base - and accelerator spray to cure it before it all wicks inside. But honestly, I like the idea of this foam solution better. It is safer for the mic, and probably better for handling noise as well.

@ Greg ,.
Yes,. I've used the foam on 4 SM57's an never had a problem ,..the grill will still rotate a Lil'
I've also used Option #2,.the Duco Cement (local ACE hardware)an is a more permanent fix
Nice thing about Duco Cement,. is it's thick enough that it does not wick a lot inside,. but will flow enough to get between the black screen and the rotating plastic grill.
The trick is a small dab of Duco cement (the size of a pin head) & breaking off the length of toothpick leaving it in place.
YA don't need to load it on.
