Fixing a bad connection

Hi all, thanks in advance for your guidance. I'm going to skip the back story and go straight to the situation at hand... The connection between my garbage disposal and the slip joint adapter (shown in the photo at Location 1) is misaligned. This means that it occasionally disconnects and I end up with a bunch of water in my cabinet. I think the easiest way to fix this problem is by cutting the drain pipe at Location 2 or Location 3, and then reconnecting the two ends using a flexible pvc coupling. I'm here to ask you all for advice on this plan... Is it a good idea? Bad idea? Thank you!

Is it misaligned or is it not the proper connection. Hard to see in the pic.

Also.... your dishwasher drain line is improperly installed. It needs to be looped up high before connecting to the disposer.

The high loop could be in corner cabinet if you did not want it in sink area. Rasie the inlet to cabinet for drain hose. Some places require a air gap installed

You need to get it aligned properly. I don't like those flex type fitting, but I suppose if all else fails...

Hard to tell from the picture, but is that a glued up trap? If so, the answer may be to cut it out and replace it with a slip trap into a trap adapter mounted just inside the cabinet. That would give you a lot more freedom to get things aligned properly because all the joints can be rotated and the length of the trap arm adjusted by sliding it in or out of the trap adapter.

I like Carbide Tipped's idea of changing over to a slip adapter when the pipe enters the cabinet. It will give you the flexibility to get everything aligned properly.

The rubber adapter you linked to isn't approved for interior use. If you want to use a rubber transition, you should use a shielded no-hub coupling:

Also, as an FYI, the connection into your 4" stack is incorrect. It should be a tee or wye... but other than knowing for the future, I wouldn't bother trying to change it out. It's close enough.
