Bad Vibration When Braking

I've started noticing a rather hard vibration when I try to come to a complete stop. My jeep will stop but the vibration keeps getting worse. I'm usually pretty good a figuring these things out but I'm at a loss. Thanks!

Could be warped rotors.

I've also never had drum brakes before so forgive my terminology when I try to explain this: the "cover" of the passenger side rear brakes almost wouldn't come off just now when I took my tire off. Now again I've never had drum brakes but I'm assuming it shouldn't be that tight.

You will have to release some of the adjustment. when you get it off you will notice a small ridge on the outside of the inner side of the drum. that is normal wear but will usually prevent the drum from coming off . If the shoe is compleately shot you should hear a grinding noise along with the viberation

I was able to wiggle the drum off but it won't go back on now. Should I just be able to adjust the shoe so it goes back on or would I be better off replacing it?

If the shoe looks ok back off some of the adjustment then re adjust when you get the drum on. Look for crack in drum this can cause viberation when applying the brakes.

I pulled the drums off and they aren't cracked. The vibration is still there and I'm not sure where else to turn at this point.

As mentioned, warped discs are the most common reason for braking vibration. One reason they warp is when you hit water when the discs are hot. My 93 GMC truck was the worst for this. About every 10K miles I had to chuck the pads and do a light turn on the discs. Problem solved.
