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?
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.
