Yeah I made this mistake the first time I rebuilt my suspension. Tightened the UCA and LCAs in the air and it squeaked like crazy a couple weeks later. Wound up having to redo all the most difficult parts of the suspension rebuild all over again.
I'm sure a lot of people don't pay that much attention to it. I know I didn't when I was using rubber bushings. I mean, I tightened everything on the ground as per the FSM but was the suspension fully settled? And I've definitely adjusted the ride height without changing the position the LCA pivots were torqued in.
Another reason to like Poly and Delrin LCA bushings. Tighten them wherever you want, doesn't make a difference.
