I'm planning to replace my front struts, (removing strut assembly with out disturbing control arms/tie rods/radius rod). Is it necessary to get an wheel alignment after removing and installing the struts?

 

Not really

 

So you're worried about the alignment changing, if you put a stock height car to stock height???
jk

It should be fine. If you're worried check your tires every oil change or 1.5k miles.

 

Thanks, good to know.
I replaced upper/lower control arms, outer tie rods and ball joints. And had the alignment done.
It would have been a perfect opportunity change out the struts while i had these parts out the car, but I didn't have the coin at the time.
