do I need alignment after changing struts?

Hi, I just changed my struts. Do I need to take it for re-alignment?
thanks.

I want to know why you think no, but I think I agree, because there is no need to remove the tie rod arm. just undo the pinch bolt, hit the knuckle down, and undo the three at top.

O and undo the sway bar link. So I vote no too, unless your lowering?

Changing just the struts out you are correct in the fact that nothing alignment wise is typically disturbed assuming the upper strut mount is put back in in the same position it was before. Or if you are replacing the strut mount. If the old one was damage in any way and either replaced or put in in a different way than what it was the camber numbers can change. This is especially apparent if the bushing is torn.

Lowering is a different animal. Lowering the car will change your camber numbers which will in turn change the toe of the vehicle. You can adjust toe without affecting camber/caster but you cannot adjust camber or caster without affecting the toe. Thats why when doing an alignment toe is always adjusted last.

Hi, I want to thank jetrinka, forddorf, and Djzx3 for their replies.
I did not lower the car, just replaced the struts. But I replaced the whole assembly, so the mount may not be exactly the same? and thus needs re-alignment?
Thanks in advance

You shouldn't need an alignment for just swapping out the same strut/spring.

You will need an alignment, I know from experience.

As little of a change that you are doing to your suspension, the struts will not settle into the same exact position that they were in before.

You should not need an alignment. You are not changing anything that changes the setting. The struts do not hold the car up the spring do that job.

Some people get lucky on just a strut change. Some don't. It's really best to check with an alignment. I wasn't lucky and it cost me a new Michelin tire. Cost of the alignment I should have had done: $79.95. Cost of purchasing, mounting and balancing the new Michelin: $120.
