Alignment Needed After New Lower Control Arm?

[StantonGTI]

Hi There,

I just replace the lower control arm on my 99 Carrera. All of the DIYs I read say I need an alignment after this is complete, but all of the DIYs are part of a larger suspension refresh (tie rods, end links, etc.) 

Since I just did the lower control arm, is an alignment necessary? I did not loosen or move any of the alignment points in replacing the control arm. In my mind (which I admit can be limited), If I did not adjust anything that can throw off the alignment, and none of the bolts I removed are used to adjust alignment (at least I don't think they are) could the alignment be off?

This is a track car, and I'm about to put 4 new tires on it, so I will most likely get the alignment done, just wondering what could cause it to change if I am not adjusting anything.

I just replaced both LCA's, with the left side having a bad/squeaky ball joint.  I found the camber (0.3 deg change) and toe had changed on the left side, but not on the right.  I would suggest the alignment.

Thanks. Already made the appointment, just in my head it makes no sense on why something would change, but I guess if some is in just a slightly different place,than what it was during last alignment, it could cause issues.
