Does loosening or dropping the rear crossmember require an alignment afterwards?

Technically, yes.

 

[sw20rules]

But in practice do people go and get an alignment? Changing the rear sway bar and replacing the b-pipe all require touching the crossmember.

it would only affect toe correct?

By practice i try to get an alignment whenever i touch the suspension. If your tires only last 5000-20000kms, its a good thing to make sure they are aligned properly

just a question to add to this. I pulled the tranny out of my car awhile ago. I took the crossmember off while doing it. Or lowered it a bunch, I cant remember now. Regardless, my alignment is jacked up now. Someone said my caster, or toe is messed up. The car wants to jolt to the right and wiggle when I speed up. Does this mean that maybe I didn't tighten the crossmember correctly?

The only adjustments in the rear are camber and toe. Lowering the crossmember would more likely disrupt toe than it would camber. Both can be affected though sometimes.

I removed my crossmember and then the engine. put it all back in and checked the alignment after. it was still right on. I tried to mark where the strut pinch flanges were with respect to the axle carriers beforehand to get the same camber afterwards. apparently in my case the toe was not affected as the crossmember must have positioned itself to the original position.
