Technically after you do any wheel/steering/subframe work you "should" get an alignment. However it'* pretty commonly accepted that swapping fixed items like bearings are close enough that the change in alignment will be little to nothing and the money is better spent in other places.

I changed a strut mount and there was no change. Thanks free 6 month alignment.

My bearing search is over I found 1 for $65 new made by WBS or WSB. Hopefully its relaible
