YES, it is necessary to have an alignment after replacing the lower control arm.
Let's face it, no two control arms are exactly alike (neither are the lower ball joint, which will be replaced as well).
So having the alignment will ensure that your tires are straight as you drive down the highway.
If you elect not to have the alignment, there is possibility of having your tires wear out sooner - this would void any tire warranty that you may have.
