Alignmnet needed after front bushing replacement?

[Multibeemer]

Merry Christmas and Happy New Year, everyone.

I recently replaced bushings 7 and 11 in the diagram below, which took care of a few clunks I was hearing:

RealOEM.com * BMW E53 X5 4.4i Frnt axle support,wishbone/tension strut

I removed the arms that these bushings are inserted into, took them to a machine shop to have the old ones pressed out and the new ones pressed in, and put them back on the X5 (yes, I torqued the bolts with the weight of the vehicle on the tires). I don't see why an alignment would be necessary, because I didn't move anything that could shift the camber or toe, but I seem to remember hearing that an alignment is advisable after a bushing replacement. What's the consensus on this? If it's that an alignment is needed, why? Thanks in advance.
